Randoop Manual

+ +

+This is the manual for Randoop version 4.3.4, released June 6, 2025. +The Randoop homepage is +https://randoop.github.io/randoop/. +

+ +

Contents:

+ + + + +

+Randoop.NET is a version of Randoop that works with Microsoft's .NET platform, such as the C# programming language. +

+ +

+There is a separate Randoop Developer's Manual. +

+ + +

Introduction

+ +

Writing tests is important, but difficult and time-consuming. Randoop +automatically generates unit tests for Java classes. +Randoop has had many +successful applications, especially with library classes (such as +java.util). Randoop is used at companies like ABB and Microsoft, and +on open-source +projects. +

+ +

+Here +is a JUnit test case +generated by Randoop that reveals an error in OpenJDK (comments +added by hand):

+ +
+
+  // This test shows that the JDK collection classes
+  // can create an object that is not equal to itself.
+  @Test
+  public static void test1() {
+
+    LinkedList list = new LinkedList();
+    Object o1 = new Object();
+    list.addFirst(o1);
+
+    // A TreeSet is an ordered collection. According to the API
+    // documentation, this constructor call should throw a
+    // ClassCastException because the list element is not Comparable. But
+    // the constructor silently (and problematically) accepts the list.
+    TreeSet t1 = new TreeSet(list);
+
+    Set s1 = Collections.synchronizedSet(t1);
+
+    // At this point, we have successfully created a set (s1)
+    // that violations reflexivity of equality: it is not equal
+    // to itself! This assertion fails at run time on OpenJDK.
+    org.junit.Assert.assertEquals(s1, s1);
+  }
+
+ +

+ Randoop outputs two kinds of tests: +

+
    +
  • + error-revealing tests that detect bugs in your current code, and +
    • +
  • + regression tests that can be used to detect future bugs. +
    • +
+ + +

Typical use of Randoop

+ +

+Here is a typical way to use Randoop: +

+ +
    +
  1. + If Randoop outputs any error-revealing tests, fix the underlying + defects, then re-run Randoop and repeat until Randoop outputs no + error-revealing tests. +
    2. +
  2. + Add the regression tests to your project's test suite. +
    3. +
  3. Run the regression tests + whenever you change your project. These tests will notify you of + changes to the behavior of your program. +
    4. +
  4. + If any test fails, minimize the test case + and then investigate the failure. +
      +
    • + If a test failure indicates you have introduced a code defect, fix + the defect. +
      • +
    • + If a test failure indicates that the test was overly brittle or + specific (for example, a method's output value has changed, but the + new value is as acceptable as the old value), then disregard the + test. +
      • +
    + If you disregarded any test (or if you added new code that you would + like to test), then re-run Randoop to generate a new regression test + suite that replaces the old one. +
    5. +
+ +

+The paper "Scaling up automated test generation: Automatically generating maintainable regression unit tests for programs" gives additional tips for how to use Randoop-generated tests over the lifetime of a project. +

+ +

+A typical +programmer will only ever examine very few Randoop tests — when they +fail and reveal a bug or a regression failure — and then only +minimized versions of them. A typical programmer will +never modify Randoop tests by hand. +

+ + +

Installing Randoop

+ +

+Randoop runs on a Java 8 or later JVM. +

+ +

+ Download and unzip the file + randoop-4.3.4.zip. + + + This manual uses ${RANDOOP_PATH} to refer to + the path of the unzipped archive, + and ${RANDOOP_JAR} to refer to + the location of randoop-all-4.3.4.jar + within the unzipped archive. +

+ +

+ Alternately, if you want to view or work with the source code, follow the instructions in + the Getting Started + section of the Randoop Developer's Manual. +

+ +

+ You may wish to join the randoop-discuss@googlegroups.com mailing list so that you are notified of new releases. +

+ + +

Running Randoop

+ +

+Run Randoop by invoking its main class randoop.main.Main: +

+ +
+java randoop.main.Main command args...
+
+ +

+Randoop supports three commands: +

+ +
    +
  • gentests generates unit tests. For details, +see Generating Tests. Example use: + +
    +java -Xmx3000m -classpath myclasspath:${RANDOOP_JAR} randoop.main.Main gentests --testclass=java.util.TreeSet --output-limit=100
+
    + +(However, note that it is extremely unusual to use the --testclass command-line argument to specify just one class under test.) +
    • + +
  • minimize minimizes a failing JUnit test suite. For details, +see Minimizing a failing JUnit test suite. +Example use: + +
    +java -cp ${RANDOOP_JAR} randoop.main.Main minimize --suitepath=ErrorTest0.java --suiteclasspath=myclasspath
+
    +
    • + +
  • help prints out a usage message. +For details, see Getting Help. +Example uses: + +
    +java -classpath ${RANDOOP_JAR} randoop.main.Main help
+java -classpath ${RANDOOP_JAR} randoop.main.Main help gentests
+java -classpath ${RANDOOP_JAR} randoop.main.Main help minimize
+
    +
    • + +
+ +

+(On Windows, adjust the classpath, such as using semicolon instead of colon +as the separator.) +

+ + + + + + + + + + + + +

Generating tests

+ +

By default, Randoop generates and then outputs two kinds of unit + tests, written to separate files. +

+
    +
  • Error-revealing tests + are tests that fail when executed, + indicating a potential error in one or more classes under test. +
    • +
  • + Regression tests + are tests that pass when executed, and + can be used to augment a regression test suite. +
    • +
+Other generated tests, classified as invalid, are discarded. + +

+This section of the manual gives an +example of how to run Randoop, then +describes +test classification, +error-revealing tests, and +regression tests, +and finally lists Randoop's command-line options.

+ + +

Example: Generating tests for java.util.Collections

+ +

Imagine we want to generate tests for the +class java.util.Collections. +(This example is a bit unrealistic! More likely you would want to generate +tests for all of the JDK, or for parts of it like java.lang +and java.util.) +

+ +

Randoop's tests only use + classes you specify. In order +to effectively test Collections, you should probably also specify some +helper classes, including classes that generate collections. For this +example, we will add java.util.TreeSet to the mix.

+ +

Create a file myclasses.txt that lists the names of the classes under test: +

+
java.util.Collections
+java.util.TreeSet
+

+and invoke Randoop as follows:

+ +
java -classpath ${RANDOOP_JAR} randoop.main.Main gentests --classlist=myclasses.txt --time-limit=60
+ + +

After 60 seconds, Randoop stops generating tests. The last thing Randoop prints out is the name of the JUnit files containing the tests it generated. You should see a message similar to the following:

+ +
Created file: my/home/directory/RegressionTest0.java
+Created file: my/home/directory/RegressionTest.java
+Created file: my/home/directory/ErrorTest0.java
+Created file: my/home/directory/ErrorTest.java
+done.
+

+Randoop creates two different test suites, in classes +ErrorTest and RegressionTest. Compile and run the tests. +(The classpath should include the code under test, the generated tests, and +JUnit files junit.jar and hamcrest-core.jar. +Classes in java.util.* are always on the Java classpath, so the +myclasspath part is not needed in this particular example, but it is +shown because you will usually need to supply it.) +

+ +
export JUNITPATH=.../junit.jar:.../hamcrest-core.jar
+javac -classpath .:$JUNITPATH ErrorTest*.java RegressionTest*.java -sourcepath .:path/to/files/under/test/
+java -classpath .:$JUNITPATH:myclasspath org.junit.runner.JUnitCore ErrorTest
+java -classpath .:$JUNITPATH:myclasspath org.junit.runner.JUnitCore RegressionTest
+ +

+All of the tests in ErrorTest will fail, and all of the tests in +RegressionTest will pass. +

+ +

+ You also might want to minimize + the error-revealing tests before running them: +

+ +
+java -cp .:junit.jar:myclasspath:.../randoop/build/libs/randoop-all-4.3.4.jar \
+  randoop.main.Main minimize --suitepath=ErrorTest0.java --suiteclasspath=.:junit-4.12.jar:myclasspath
+
+ + +

Specifying methods, constructors, and fields that may appear in a test

+ +

+ You need to tell Randoop what code it may call. In the common case of + running Randoop on an entire program or library, it is usually enough to run + Randoop on the .jar file. + If you want to generate tests for only specific classes, then you need to do more work. +

+ +

+ Suppose you want to + test method A.m. You should direct Randoop to call not just + A.m, but also methods that create A.m's inputs. + More concretely, if A.m's parameter type is B, + then you should tell Randoop to also call methods or constructors that + create objects of type B. When a test calls + A.m, all of the methods that set up state or create + argument values are also being implicitly tested. +

+ +

+This command gives you an over-estimate (because it includes method call +types as well as method argument types): +

+ +
+  jdeps -apionly -v -R -cp myclasspath MyClass.class \
+    | grep -v '^[A-Za-z]' | sed -E 's/^.* -> ([^ ]+) .*$/\1/' | sort | uniq
+
+ +

+You may want to adjust the command-line arguments. For example, you can +pass a .jar file instead of a .class file. Or, +you could remove -R (and possibly run it twice to get depth-2 +instead of depth-1). +You may want to remove -apionly if you wish to see all +the Java runtime methods that are referenced. +

+ +

+It is unusual to specify just one or a few classes under test. +Usually, you want to test an entire application or library. +Specifying too few classes under test can prevent Randoop from achieving good coverage. +

+ + +

Which methods Randoop will call

+ +

+Randoop only invokes a method or constructor M if all of the following are true: +

+ +
    +
  1. M is declared in a class that is named by + --testjar, + --classlist, or + --testclass, + or M is a + member named by --methodlist. +
    2. +
  2. M does not match any of the patterns given + via --omit-methods + or + --omit-methods-file. +
    3. +
  3. All of the following are accessible from the package of the tests + (set with --junit-package-name): + M's class, M, and M's parameter types and + return type. +
    4. +
+ +

+A method or constructor M that satisfies the above conditions is called +a "method under test". +Randoop only calls methods under test; that is, these are the only +methods that will appear in a test case. +

+ +

+ Use raw type names such as List, not parameterized types such + as List<String>, when specifying classes or methods. +

+ +

+ Do not include methods that side-effect global state, for two reasons. + (Methods that side-effect the state of their receiver or other arguments are fine.) +

+
    +
  • Such methods create dependent tests that cannot be run + in isolation or reordered. + For example, if test A side-effects global state and test B reads global + state, then whether test B passes depends on whether test A is run before + test B. +
    • +
  • If you ask Randoop to test code that modifies your file system (such as + File.delete()), + then Randoop will generate tests that modify your file system! + Be careful when choosing classes and methods to test. +
    • +
+ +

+Note that you may include members of the Java runtime libraries in your list of +classes to test. Randoop will generate tests to exercise these methods. +However, you cannot use Jacoco to check for coverage of JDK classes or methods, +because the Jacoco coverage tool cannot collect any data from the Java runtime +libraries. +

+ + +

Classifying tests

+ +

+Randoop generates many tests internally, and it classifies each generated test as +error-revealing, expected behavior, or invalid. The classification depends +primarily on whether the last statement throws an exception or +violates a contract. +You can also provide specifications of the methods under test to further help +Randoop classify tests; see section +"Specifying expected code behavior". +

+ +

+You can use command-line arguments to customize Randoop's rules for +classifying a test that throws an exception. +

+
    +
  • Checked exceptions: By default, Randoop classifies a test that throws + a checked exception as expected behavior. You can override this default + with the --checked-exception + command-line option; specify + --checked-exception=error, + --checked-exception=expected, or + --checked-exception=invalid. +
    • +
  • OutOfMemoryError or StackOverflowError. Options: +--oom-exception +and --sof-exception; +default invalid
    • +
  • NullPointerException when null is passed as + an argument to any method in the test. +Option: --npe-on-null-input; default expected +
    • +
  • NullPointerException when only non-null + values are provided as an argument. +Option: --npe-on-non-null-input; default invalid
    • +
  • Unchecked exceptions other than OutOfMemoryError +and NullPointerException, +including AssertionError. +Option: +--unchecked-exception; default expected
    • +
+ +

+By default, a thrown exception is not considered to indicate an +error in the code under test. (Equivalently, none of the above +command-line arguments defaults to ERROR.) This is because a +method may have a precondition that is unknown to Randoop. For example, a +binary search implementation might require that its input is sorted. +Randoop should not mark the method as buggy just because it throws an +exception when Randoop passes it an ill-formed unsorted array. Another +example is passing null to a method that requires a non-null +argument, which might result in a NullPointerException, AssertionError, or +other exception. Randoop has no way of knowing each method's precondition. +In order to avoid outputting an "error-revealing test" that doesn't reveal +an error but merely misuses the software under test, by default Randoop +assumes that any exception thrown by a method is correct behavior in +response to the values that it was passed. +

+ + +

Error-revealing tests

+ +

+When Randoop includes a error-revealing test in file ErrorTest.java, +the test shows that the code +violates its specification or contract. For example, the test shown in +the Introduction +creates a TreeSet that +violates reflexivity of equality: namely, for every +object o, o.equals(o) should +return true. +The test reveals an error in the TreeSet constructor, which does +not properly check its arguments (and possibly a second error in the +TreeSet.equals method, which should always check if its argument +is the same object as itself and return true in such a case). +

+ +

+The test in the Introduction is nicely +succinct: it shows a small number of method calls leading up to the +assertion violation. Because Randoop's generation is pseudo-random, the actual +test revealing the error can be significantly longer, and contain many +irrelevant calls that are not necessary to reveal the contract violation. +You may wish to minimize the test +case to ease debugging. +

+ + +

What kinds of errors does Randoop check for?

+ +

+ When Randoop calls a method that creates an object, Randoop verifies that + the object is well-formed. + Currently, Randoop checks for the following contracts:

+ +
    +
  • Contracts over Object.equals(): +
      +
    • Reflexivity: o.equals(o) == true
      • +
    • Symmetry: o1.equals(o2) == o2.equals(o1)
      • +
    • Transitivity: o1.equals(o2) && o2.equals(o3) ⇒ o1.equals(o3)
      • +
    • Equals to null: o.equals(null) == false
      • +
    • it does not throw an exception
      • +
    +
    • +
  • Contracts over Object.hashCode(): +
      +
    • Equals and hashcode are consistent: If o1.equals(o2)==true, then o1.hashCode() == o2.hashCode()
      • +
    • it does not throw an exception
      • +
    +
    • +
  • Contracts over Object.clone(): +
      +
    • it does not throw an exception, including CloneNotSupportedException
      • +
    +
    • +
  • Contracts over Object.toString(): +
      +
    • it does not throw an exception
      • +
    • it does not return null
      • +
    +
    • +
  • Contracts over Comparable.compareTo() and Comparator.compare(): +
      +
    • Reflexivity: o.compareTo(o) == 0 (implied by anti-symmetry)
      • +
    • Anti-symmetry: sgn(o1.compareTo(o2)) == -sgn(o2.compareTo(o1))
      • +
    • Transitivity: o1.compareTo(o2)>0 && o2.compareTo(o3)>0 ⇒ o1.compareTo(o3)>0
      • +
    • Substitutability of equals: x.compareTo(y)==0 ⇒ sgn(x.compareTo(z)) == sgn(y.compareTo(z))
      • +
    • Consistency with equals(): (x.compareTo(y)==0) == x.equals(y) (this contract can be disabled)
      • +
    • it does not throw an exception
      • +
    +
    • +
  • Contracts over checkRep() (that is, any nullary method annotated with @CheckRep): +
      +
    • it does not throw an exception
      • +
    • if its return type is boolean, it returns true
      • +
    +
    • +
+ +

+Violation of any of these contracts is highly likely to indicate an error. +

+ +

+You can add additional contracts to Randoop, that will be checked for every object Randoop creates. +Define a contract in directory +randoop/src/main/java/randoop/contract/, +and reference it in the constructor for OperationModel. +You can also provide specifications of methods in the tested code to help +Randoop classify tests; see section +"Specifying expected code behavior". +

+ + +

Regression tests

+ +

+The tests in the RegressionTest*.java files assert the current behavior +of the code under test: values returned or exceptions thrown. After you change your +code, you can run these regression tests, which will alert you if your +code changes affect the external behavior of the classes. +

+ +

+Here is an example of a regression test for +the TreeSet class:

+ +
// This test passes when executed
+@Test
+public void test10() throws Throwable {
+
+  java.util.TreeSet var0 = new java.util.TreeSet();
+  java.lang.Short var1 = new java.lang.Short((short)100);
+  boolean var2 = var0.contains(var1);
+
+  // Regression assertion (captures the current behavior of the code)
+  org.junit.Assert.assertEquals(false, var2);
+}
+ +

This test would fail if you introduced an error that caused contains to return true on an empty set.

+ +

+A regression test can also assert what exception is currently thrown, +and it will fail if the code is changed to no longer throw that exception. +

+ + +

Regression test failures

+ +

+If a regression test fails even though you have not changed your program, +then the test is flaky. +

+ +

+If a regression test fails after you change your program, there are three +possible causes. You need to debug the test failure to determine which is +the cause, and then take the appropriate action. +

+
    +
  • + You have introduced an error — your code changes are incorrect.
    + In this case, you should correct your mistake and re-run the test suite. +
    • +
  • + You have intentionally changed the visible behavior of your program. The + regression test has corroborated the change.
    + In this case, you need to update the tests. Most commonly, you will just + discard them and generate new ones. +
    • +
  • + The tests are too sensitive, and they have failed even though you made + an inconsequential change. For example, maybe + the tests depend on the order of elements in a hash + table.
    + In this case, you need to re-run + Randoop, informing it + not to depend on observations that may vary from run to run. + You can also see the techniques suggested in the paper + Scaling + Up Automated Test Generation. +
    • +
+ +

+Usually, a change to your program causes many test failures, not just one. +This is because Randoop generates many tests for each part of your +program's functionality. Don't panic! In most cases, all of the failures +have the same cause. +

+ + +

Verifying the cause of regression test failures

+ +

+You may wish to verify the cause of the failures. A way to do this is to +change the part of the program, that you suspect is the cause, back to its +previous behavior. Once you are satisfied that you understand the +failures, you can discard the tests and have Randoop generate new ones. +For example, suppose that you believe that all the test failures are caused +by a change to method m. You can change m back to its +previous implementation and run the tests. If they all succeed, you can +change m back to its new implementation and re-generate the tests. +(As an alternative to making a temporary change to your source code, you +can use +the replacecall feature of the Randoop +agent to replace the new functionality by the old functionality.) +

+ + +

Stages of test generation, and limiting test generation

+ +

+Here is how Randoop attempts to generate a test: +

+ +
    +
  1. + Randoop selects a method to call. (This is called a "step".) The + selected method will be the last method call in the new test. +
    2. +
  2. + Randoop chooses arguments to the method call, from among values that + have been computed by previous tests.
    + If Randoop cannot find values + that are different from those in every previous call to the method, then + Randoop starts over choosing arguments.
    + Otherwise, Randoop + has created a test candidate — a new, unique sequence of operations that + ends with the selected method. + The candidate's code is the concatenation of the code to produce the + arguments (except that for primitives, just the value itself is used), + followed by the method call. +
    3. +
  3. + Randoop executes the test candidate + and classifies its behavior. If its + behavior is invalid, then Randoop discards it and starts over. +
    4. +
  4. + Randoop outputs error-revealing and regression tests, in separate suites. +
    5. +
+ +

+ The user can provide limits on any part of the test generation process, or on + Randoop's run time. Test generation stops when any of the following occurs + (this is controlled by method AbstractGenerator.shouldStop): +

+
    +
  • + The time limit (--time-limit) + is reached. +
    • +
  • + The number of attempts to generate a sequence reaches the step limit + (--attempted-limit). +
    • +
  • + The number of generated sequences reaches the input limit + (--generated-limit). +
    • +
  • + The number of error-revealing and regression tests reaches the output + limit (--output-limit). +
    • +
  • + One error-revealing test is generated, and + --stop-on-error-test=true + was supplied. +
    • +
  • + A custom Stopper was provided and indicates that + generation should stop (see the Randoop code). +
    • +
+ +

+ Randoop does not optimize to generate the best suite within these limits. + Rather, Randoop just halts when a limit is reached. +

+ +

+Furthermore, see the command-line options +for threading for additional per-test time limits. +

+ + +

Minimizing a failing JUnit test suite

+ +

+Minimized test cases are usually easier to diagnose. +Randoop includes a minimizer that, given a JUnit test suite, +minimizes each failing test case. +Each minimized test fails in the same way as the original, having the +same failing assertions with the same stack trace. +The minimizer works by removing and simplifying methods and statements in its +input file, without changing the test suite's failure behavior. +

+ +

+ There are two ways to use the minimizer: +

+
    +
  • + Supply --minimize-error-test, + and Randoop minimizes each error-revealing test before outputting it. +
    • +
  • + Use Randoop's minimize command. + The minimizer can be used with any JUnit test suite: it can + minimize failing tests that Randoop did not create. +
    • +
+ +

+ For both ways to use the minimizer, see the documentation for the + command-line + options for failing test suite minimization. +

+ +

+ The rest of this section discusses Randoop's minimize command. +

+ +

+To minimize all failing tests in ErrorTest1.java, run +Randoop as follows: +

+
+java -cp randoop-all-4.3.4.jar randoop.main.Main minimize \
+  --suitepath=ErrorTest0.java --suiteclasspath=junit.jar:commons-lang.jar --testsuitetimeout=30
+
+ +

+The minimizer produces a Java file +named InputTestSuiteMinimized.java +where InputTestSuite.java is the file +being minimized. + +

+ +

+ The minimizer creates a new output file, rather than modifying the + original test suite in place, because sometimes the minimization loses + important information. For example, when a test case fails due to a + NullPointerException, the minimizer might replace the right + hand side of an expression with the value null. +

+ + + +

Customizing Randoop's behavior to your application

+ +

+If you run Randoop without any command-line arguments or customizations to +your environment, it will produce helpful tests. However, Randoop will +produce much more helpful tests if you spend a little bit of time to tell +Randoop about your application, and that is how we recommend using Randoop. +

+ + +

Command-line options

+ + +
    +
  • Code under test: which classes and members may be used by a test +
      +
    • --testjar=filename [+]. + Treat every class in the given jar file as a class to test. The jarfile must be on the + classpath. + +

      See the notes about specifying methods that may + appear in a test. +

    • --test-package=string [+]. + Package to test. All classes on the classpath within the package are classes to test. Does not + include classes in sub-packages. + +

      The classes in the package are tested in addition to any specified using --testjar, + --testclass, and --classlist +

    • --classlist=filename. + File that lists classes to test. All of their methods are methods under test. + +

      In the file, each class under test is specified by its binary name on a separate line. See + an example. + These classes are tested in addition to any specified using --testjar, + --test-package, and --testclass. + +

      Using --classlist is less common than --testjar. See the notes about specifying methods that may + appear in a test. +

    • --testclass=string [+]. + The fully-qualified raw name of a class to test; for example, + --testclass=java.util.TreeSet. All of its methods are methods under test. This class is tested + in addition to any specified using --testjar, --test-package, and + --classlist. + +

      It is unusual to specify just one or a few classes to test. See the notes about specifying methods that may + appear in a test. +

    • --methodlist=filename. + A file containing a list of methods and constructors to call in tests, each given as a fully-qualified + signature on a separate line. + +

      These methods augment any methods from classes given by the --testjar, + --classlist, and --testclass options. + +

      See an example + file. + +

      Using --methodlist is less common, and more error-prone, than --testjar, + --test-package, --classlist, or --testclass. See the notes about specifying methods that may + appear in a test. +

    • --omit-classes=regex [+]. + A regex that indicates classes that should not be used in tests, even if included by some other + command-line option. The regex is matched against fully-qualified class names. If the regular + expression contains anchors "^" or "$", they refer to the beginning and the end + of the class name. +
    • --omit-classes-file=filename [+]. + A file containing a list of regular expressions that indicate classes not to call in a test. + These patterns are used along with those provided with --omit-classes. +
    • --omit-methods=regex [+]. + A regex that indicates methods that should not be called directly in generated tests. This does + not prevent indirect calls to such methods from other, allowed methods; to prevent them, see + the + replacecall agent. + +

      Randoop will not directly call a method whose fully-qualified + signature matches the regular expression, or a method inherited from a superclass or + interface whose signature matches the regular expression. + +

      If the regular expression contains anchors "^" or "$", they refer to the + beginning and the end of the signature string. + +

      Methods replaced by the replacecall + agent are also automatically omitted. +

    • --omit-methods-file=filename [+]. + A file containing a list of regular expressions that indicate methods that should not be + included in generated tests. These patterns are used along with those provided with + --omit-methods, and the default omissions. +
    • --omit-field=string [+]. + A fully-qualified field name of a field to be excluded from test generation. An accessible + field is used unless it is omitted by this or the --omit-field-file option. +
    • --omit-field-file=filename. + File that contains fully-qualified field names to be excluded from test generation. An + accessible field is used unless it is omitted by this or the --omit-field option. +
    • --only-test-public-members=boolean. + Restrict tests to only call public members of classes. + +

      When this is false, the setting of --junit-package-name and package accessibility is + used to determine which members will be used in tests. [default: false] +

    • --silently-ignore-bad-class-names=boolean. + Ignore class names specified by user that cannot be found [default: false] +
    • --flaky-test-behavior=enum. + What to do if Randoop generates a flaky test. A flaky test is one that behaves differently on + different executions. + +

      Flaky tests are usually due to calling Randoop on side-effecting or nondeterministic + methods, and ultimately, the solution is not to call Randoop on such methods; see section Nondeterminism in + the Randoop manual. [default: OUTPUT] +

        +
      • HALT Randoop halts with a diagnostic message. You can determine the responsible methods, fix or + exclude them, and re-run Randoop. +
      • DISCARD Discard the flaky test. This option should be a last resort. It is inefficient and + unproductive for Randoop to produce and discard a lot of flaky tests. +
      • OUTPUT Output the flaky test, but with flaky assertions commented out. When the value is + OUTPUT, Randoop also suggests methods under test that might have caused the flakiness. You + should investigate + them, fix or exclude them, then re-run Randoop. +
      + +
    • --nondeterministic-methods-to-output=int. + How many suspected side-effecting or nondeterministic methods (from the program under test) to + print. [default: 10] +
    +
  • Which tests to output +
      +
    • --no-error-revealing-tests=boolean. + Whether to output error-revealing tests. Disables all output when used with + --no-regression-tests. Restricting output can result in long runs if the default values of + --generated-limit and --time-limit are used. [default: false] +
    • --no-regression-tests=boolean. + Whether to output regression tests. Disables all output when used with + --no-error-revealing-tests. Restricting output can result in long runs if the default values + of --generated-limit and --time-limit are used. [default: false] +
    • --no-regression-assertions=boolean. + Whether to include assertions in regression tests. If false, then the regression tests contain + no assertions (except that if the test throws an exception, it should continue to throw an + exception of the same type). Tests without assertions can be used to exercise the code, but + they do not enforce any particular behavior, such as values returned. [default: false] +
    • --check-compilable=boolean. + Whether to check that generated sequences can be compiled. If true, the code for each generated + sequence is compiled, and the sequence is only kept if the compilation succeeds without error. + This check is useful because the assumptions in Randoop generation heuristics are sometimes + violated by input methods, and, as a result, a generated test may not compile. This check does + increases the runtime by approximately 50%. [default: true] +
    • --require-classname-in-test=regex. + Classes that must occur in a test. Randoop will only output tests whose source code has at + least one use of a member of a class whose name matches the regular expression. +
    • --require-covered-classes=filename. + File containing binary names of classes that the tests must use, directly or indirectly. This + option only works if Randoop is run using the covered-class + javaagent to instrument the classes. A test is output only if it uses at least one of the + class names in the file. A test uses a class if it invokes any constructor or method of the + class, directly or indirectly (the constructor or method might not appear in the source code of + the test). Included classes may be abstract. +
    • --minimize-error-test=boolean. + If true, Randoop outputs both original error-revealing tests and a minimized version. Setting + this option may cause long Randoop run times if Randoop outputs and minimizes more than about + 100 error-revealing tests; consider using + --stop-on-error-test=true. Also see the test + case minimization options. [default: false] +
    +
  • Test classification +
      +
    • --checked-exception=enum. + If a test throws a checked exception, should it be included in the error-revealing test suite + (value: ERROR), regression test suite (value: EXPECTED), or should it be discarded (value: + INVALID)? [default: EXPECTED] +
        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +
      + +
    • --unchecked-exception=enum. + If a test throws an unchecked exception other than ConcurrentModificationException, + NoClassDefFoundError, NullPointerException, OutOfMemoryError, and + StackOverflowError, should the test be included in the error-revealing test suite + (value: ERROR), regression test suite (value: EXPECTED), or should it be discarded (value: + INVALID)? + +

      The arguments --cm-exception, --ncdf-exception, --npe-on-null-input, + --npe-on-non-null-input, --oom-exception, and --sof-exception handle + special cases of unchecked exceptions. [default: EXPECTED] +

        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +
      + +
    • --cm-exception=enum. + If a test throws a ConcurrentModificationException exception, should it be included in + the error-revealing test suite (value: ERROR), regression test suite (value: EXPECTED), or + should it be discarded (value: INVALID)? [default: INVALID] +
        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +

    • --npe-on-null-input=enum. + If a test that passes null as an argument throws a NullPointerException, should + the test be be included in the error-revealing test suite (value: ERROR), regression test suite + (value: EXPECTED), or should it be discarded (value: INVALID)? [default: EXPECTED] +
        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +
      + +
    • --npe-on-non-null-input=enum. + If a test that never passes null as an argument throws a NullPointerException, + should the test be included in the error-revealing test suite (value: ERROR), regression test + suite (value: EXPECTED), or should it be discarded (value: INVALID)? [default: ERROR] +
        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +
      + +
    • --oom-exception=enum. + If a test throws an OutOfMemoryError exception, should it be included in the + error-revealing test suite (value: ERROR), regression test suite (value: EXPECTED), or should + it be discarded (value: INVALID)? [default: INVALID] +
        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +
      + +
    • --sof-exception=enum. + If a test throws a StackOverflowError exception, should it be included in the + error-revealing test suite (value: ERROR), regression test suite (value: EXPECTED), or should + it be discarded (value: INVALID)? [default: INVALID] +
        +
      • ERROR Occurrence of exception reveals an error. +
      • EXPECTED Occurrence of exception is expected behavior. +
      • INVALID Occurrence of exception indicates an invalid test. +
      + +
    +
  • Specifications for methods/constructors +
      +
    • --specifications=filename [+]. + Read file of specifications; see manual section "Specifying + expected code behavior". +
    • --use-jdk-specifications=boolean. + Use built-in specifications for JDK classes and for classes that inherit from them, as if they + had been supplied using the --specifications command-line argument. [default: true] +
    • --ignore-condition-compilation-error=boolean. + Make Randoop proceed, instead of failing, if the Java condition text of a specification cannot + be compiled. [default: false] +
    • --ignore-condition-exception=boolean. + Make Randoop treat a specification whose execution throws an exception as returning + false. If true, Randoop treats x.f == 22 equivalently to the wordier x != null + && x.f == 22. If false, Randoop halts when a specification throws an exception. [default: false] +
    +
  • Side-effect-free methods +
      +
    • --side-effect-free-methods=filename. + File containing side-effect-free methods (also known as "pure methods"), each given as a fully-qualified + signature on a separate line. Specifying side-effect-free methods has two benefits: it + makes regression tests stronger, and it helps Randoop create smaller tests. +
    +
  • Limiting test generation +
      +
    • --time-limit=int. + Maximum number of seconds to spend generating tests. Zero means no limit. If nonzero, Randoop + is nondeterministic: it may generate different test suites on different runs. + +

      This is the overall limit, not the limit per class under test. The default value is too + small to be effective for generating tests for an entire project. If you are testing multiple + classes, you may wish to multiply the default value by the number of classes under test. + +

      Randoop may run for longer than this because of a long-running test. The elapsed time is + checked after each test, not during a test's execution. [default: 100] +

    • --attempted-limit=int. + Maximum number of attempts to generate a test method candidate. [default: 100000000] +
    • --generated-limit=int. + Maximum number of test method candidates generated internally. [default: 100000000] +
    • --output-limit=int. + The maximum number of regression and error-revealing tests to output. If there is no output, + this limit has no effect. There is no output when using either --dont-output-tests or + --no-error-revealing-tests together with --no-regression-tests. + +

      In the current implementation, the number of tests in the output can be substantially + smaller than this limit. One reason is that Randoop does not output subsumed tests, which + appear as a subsequence of some longer test. [default: 100000000] +

    • --maxsize=int. + Do not generate tests with more than this many statements. [default: 100] +
    • --stop-on-error-test=boolean. + Stop generation as soon as one error-revealing test has been generated. Implies + --minimize-error-test. [default: false] +
    +
  • Values used in tests +
      +
    • --null-ratio=double. + Use null with the given frequency as an argument to method calls. + +

      For example, a null ratio of 0.05 directs Randoop to use null as an input 5 percent + of the time when a non-null value of the appropriate type is available. + +

      Unless --forbid_null is supplied, a null value will still be used if no + other value can be passed as an argument even if --null-ratio=0. + +

      Randoop never uses null for receiver values. [default: 0.05] +

    • --forbid-null=boolean. + Do not use null as input to methods or constructors, even when no other argument value + can be generated. + +

      If true, Randoop will not generate a test when unable to find a non-null value of + appropriate type as an input. This could result in certain class members being untested. [default: false] +

    • --literals-file=string [+]. + A file containing literal values to be used as inputs to methods under test, or "CLASSES". + +

      Literals in these files are used in addition to all other constants in the pool. For the + format of this file, see documentation in class randoop.reflection.LiteralFileReader. + The special value "CLASSES" (with no quotes) means to read literals from all classes under + test. +

    • --literals-level=enum. + How to use literal values that are specified via the --literals-file command-line + option. [default: CLASS] +
        +
      • NONE Do not use literals specified in a literals file. +
      • CLASS A literal for a given class is used as input only to methods of that class. +
      • PACKAGE A literal is used as input to methods of any classes in the same package. +
      • ALL Each literal is used as input to any method under test. +
      + +
    • --method-selection=enum. + Randoop generates new tests by choosing from a set of methods under test. This controls how the + next method is chosen, from among all methods under test. [default: UNIFORM] +
        +
      • UNIFORM Select methods randomly with uniform probability. +
      • BLOODHOUND The "Bloodhound" technique from the GRT paper prioritizes methods with lower branch coverage. + It weights each method under test based on the method's branch coverage and the number of + times the method is chosen for a new sequence. It requires the Jacoco code coverage tool; run + Randoop with -Xbootclasspath/a:/path/to/jacocoagent.jar + -javaagent:/path/to/jacocoagent.jar. Note that the Jacoco coverage tool cannot collect any + data from the Java runtime libraries, e.g., java.lang; thus they are not useful + candidates for the Bloodhound technique. +
      + +
    • --string-maxlen=int. + Maximum length of strings in generated tests, including in assertions. Strings longer than 65KB + (or about 10,000 characters) may be rejected by the Java compiler, according to the Java + Virtual Machine specification. [default: 1000] +
    +
  • Varying the nature of generated tests +
      +
    • --alias-ratio=double. + Try to reuse values from a sequence with the given frequency. If an alias ratio is given, it + should be between 0 and 1. + +

      A ratio of 0 results in tests where each value created within a test input is typically used + at most once as an argument in a method call. A ratio of 1 tries to maximize the number of + times values are used as inputs to parameters within a test. [default: 0.0] +

    • --input-selection=enum. + Randoop generates new tests by combining old previously-generated tests. This controls how the + old tests are chosen, from among all existing tests. [default: UNIFORM] +
        +
      • ORIENTEERING Favor sequences with lower number of method calls and cumulative execution time. +
      • SMALL_TESTS Favor shorter sequences. This makes Randoop produce smaller JUnit tests. +
      • UNIFORM Select sequences uniformly at random. +
      + +
    • --clear=int. + Clear the component set each time it contains the given number of inputs. + +

      Randoop stores previously-generated tests in a "component" set, and uses them to generate + new tests. Setting this variable to a small number can sometimes result in a greater variety of + tests generated during a single run. [default: 100000000] +

    • --clear-memory=long. + Clear the component set each time Randoop uses this much memory. + +

      Setting this variable to a smaller number may prevent an out-of-memory exception or a run + that is slow due to thrashing and garbage collection. [default: 4000000000] +

    +
  • Outputting the JUnit tests +
      +
    • --testsperfile=int. + Maximum number of tests to write to each JUnit file. [default: 500] +
    • --error-test-basename=string. + Base name (no ".java" suffix) of the JUnit file containing error-revealing tests [default: ErrorTest] +
    • --regression-test-basename=string. + Class name for the JUnit regression tests. Equivalently, the base name (no ".java" suffix) of + the JUnit file containing regression tests [default: RegressionTest] +
    • --junit-package-name=string. + Name of the package for the generated JUnit files. Enables testing non-public members. Tests + can be restricted to public members only by also using the option + --only-test-public-members. +
    • --junit-before-each=string. + Name of file containing code text to be added to the @Before-annotated + method of each generated test class. Code is uninterpreted, and, so, is not run during + generation. Intended for use when run-time behavior of classes under test requires setup + behavior that is not needed for execution by reflection. (The annotation @Before is + JUnit 4, and @BeforeEach is JUnit 5.) +
    • --junit-after-each=string. + Name of file containing code text to be added to the @After -annotated + method of each generated test class. Intended for use when run-time behavior of classes under + test requires tear-down behavior that is not needed for execution by reflection. Code is + uninterpreted, and, so, is not run during generation. (The annotation @After is JUnit + 4, and @AfterEach is JUnit 5.) +
    • --junit-before-all=string. + Name of file containing code text to be added to the @BeforeClass-annotated + method of each generated test class. Intended for use when run-time behavior of classes under + test requires setup behavior that is not needed for execution by reflection. Code is + uninterpreted, and, so, is not run during generation. (The annotation @BeforeClass is + JUnit 4, and @BeforeAll is JUnit 5.) +
    • --junit-after-all=string. + Name of file containing code text to be added to the @AfterClass-annotated + method of each generated test class. Intended for use when run-time behavior of classes under + test requires tear-down behavior that is not needed for execution by reflection. Code is + uninterpreted, and, so, is not run during generation. (The annotation @AfterClass is + JUnit 4, and @AfterAll is JUnit 5.) +
    • --junit-output-dir=string. + Name of the directory in which JUnit files should be written. +
    • --dont-output-tests=boolean. + Run test generation without output. May be desirable when running with a visitor. + +

      NOTE: Because there is no output, the value of --output-limit will never be met, so + be sure to set --generated-limit or --time-limit to a reasonable value when + using this option. [default: false] +

    • --junit-reflection-allowed=boolean. + Whether to use JUnit's standard reflective mechanisms for invoking tests. JUnit's reflective + invocations can interfere with code instrumentation, such as by the DynComp tool. If that is a + problem, then set this to false and Randoop will output tests that use direct method calls + instead of reflection. The tests will include a main method and will execute methods + and assertions, but won't be JUnit suites. [default: true] +
    +
  • Runtime environment +
      +
    • -D --system-props=string [+]. + System properties that Randoop will set similarly to java -D, of the form "x=y". +
    • --jvm-max-memory=string. + How much memory Randoop should use when starting new JVMs. This only affects new JVMs; you + still need to supply -Xmx... when starting Randoop itself. [default: 3000m] +
    +
  • Controlling randomness +
      +
    • --randomseed=int. + The random seed to use in the generation process. You do not need to provide this option to + make Randoop deterministic, because Randoop is deterministic by default. It is recommended to + run Randoop multiple times with a different random seed, in order to produce multiple different + test suites. [default: 0] +
    • --deterministic=boolean. + By default, Randoop is deterministic: running Randoop twice with the same arguments will + produce the same test suite, so long as the program under test is deterministic. (To produce + multiple different test suites, use the --randomseed command-line option.) However, + there are command-line arguments that make Randoop non-deterministic. Passing + --deterministic makes Randoop fail if one of the non-deterministic command-line arguments is + also passed; that is, passing --deterministic is a way to ensure you are not invoking + Randoop in a way that may lead to non-deterministic output. The --deterministic command + line argument doesn't itself do anything except check other command-line arguments. [default: false] +
    +
  • Logging, notifications, and troubleshooting Randoop +
      +
    • --progressdisplay=boolean. + Run noisily: display information such as progress updates. [default: true] +
    • --progressintervalmillis=long. + Display a progress message every <int> milliseconds; -1 means no display. [default: 60000] +
    • --progressintervalsteps=long. + Display a progress message every <int> attempts to create a test; -1 means none. [default: 1000] +
    • --debug-checks=boolean. + Perform expensive internal checks (for Randoop debugging). [default: false] +
    • --all-logs=boolean. + Turns on all the logs. [default: false] +
    • --log=filename. + A file to which to log lots of information. If not specified, no logging is done. Enabling the + logs slows down Randoop. +
    • --selection-log=filename. + A file to which to log selections; helps find sources of non-determinism (randomness). If not + specified, no logging is done. +
    • --operation-history-log=filename. + A file to which to write operation usage, when Randoop exits. +
    • --print-non-compiling-file=boolean. + True if Randoop should print generated tests that do not compile, which indicate Randoop bugs. [default: false] +
    +
  • Advanced extension points +
      +
    • --visitor=string [+]. + Install the given runtime visitor. See class randoop.ExecutionVisitor. +
    +
  • Test case minimization +
      +
    • --suitepath=string. + The Java file whose failing tests will be minimized. +
    • --suiteclasspath=string. + Classpath that includes dependencies needed to compile and run the JUnit test suite being + minimized. +
    • --minimizetimeout=int. + The maximum number of seconds allowed for the entire minimization process. [default: 600] +
    • --testsuitetimeout=int. + The maximum number of seconds allowed for the entire test suite to run. [default: 30] +
    • --verboseminimizer=boolean. + Produce verbose diagnostics to standard output if true. [default: false] +
    +
  • Threading +
      +
    • --usethreads=boolean. + If true, Randoop executes each test in a separate thread and kills tests that take too long to + finish, as determined by the --call-timeout-millis command-line argument. Tests killed + in this manner are not reported to the user, but are recorded in Randoop's log. Use the + --log command-line option to make Randoop produce the log. + +

      Use this option if Randoop does not terminate, which is usually due to execution of code + under test that results in an infinite loop or that waits for user input. The downside of this + option is a BIG (order-of-magnitude) decrease in generation speed. The tests are run in + parallel, but not in isolation. [default: false] +

    • --timed-out-tests=filename. + If specified, Randoop logs timed-out tests to the specified file. Has no effect unless the + --usethreads command-line option is given. +
    • --call-timeout-millis=int. + After this many milliseconds, a non-returning method call, and its associated test, are stopped + forcefully. Only meaningful if --usethreads is also specified. [default: 5000] +
    +
+ +[+] means option can be specified multiple times + + +

+A "binary name" +is like a fully-qualified name, but uses "$" to separate nested classes from +their containing classes, rather than ".". +
+A Randoop "fully-qualified signature" is +

+
    +
  • package-name.classname.method-name(argument-list) for a method, or +
  • package-name.classname(argument-list) for a constructor +
+ +

+where package-name is a period-separated list of identifiers, +and argument-list is a comma-separated list of fully-qualified +Java raw types, without spaces. Recall that a raw type does not contain +type parameters. Compared to a regular type, it removes type parameter +declarations such as <T>, and it and replaces any +use of a type parameter by its upper bound. +

+ + +

Avoiding calls to specific methods: the replacecall agent

+ +

+The code under test might make calls to methods that you do not want executed. +Here are some examples. +

+
    +
  • System.exit will terminate Randoop if called during test generation.
    • +
  • JOptionPane.showConfirmDialog opens a modal dialog box requiring user interaction, which interferes with automated testing.
    • +
  • The no-argument Random() constructor uses a randomly-chosen seed, so tests might behave differently on each execution.
    • +
+

+It is not enough to use --omit-methods to +prevent direct calls to these methods, because the methods may still be called indirectly. +To prevent all calls to these methods (including direct calls), use the replacecall agent. +

+ +

+The Randoop replacecall agent transforms the code under test, replacing +each call to an undesired method by a call to some other method. +To use it: +

+
    +
  • When running Randoop, pass the following command-line options to java: +
    +-Xbootclasspath/a:${RANDOOP_PATH}/replacecall-4.3.4.jar -javaagent:${RANDOOP_PATH}/replacecall-4.3.4.jar
+
    +
    • +
  • When running the generated tests, add the file replacecall-4.3.4.jar to the boot class path, + and pass the same command-line options to java: +
    +-Xbootclasspath/a:${RANDOOP_PATH}/replacecall-4.3.4.jar -javaagent:${RANDOOP_PATH}/replacecall-4.3.4.jar
+
    +
    • +
+ +

+Randoop uses a +default set of replacements. +You can define additional replacements. + + +

Replacement exclusions

+ +

+There are some classes that the replacecall agent should not transform. +Suppose you are using Gradle to run Randoop or the generated tests. +Randoop's replacement of System.exit +will affect the behavior of the build. +

+ +

+The replacecall agent never modifies +

+
    +
  • Randoop, including the agent
    • +
  • JUnit and Hamcrest
    • +
  • Gradle
    • +
  • Classes in rt.jar, except in packages java.awt and javax.swing
    • +
+

+(The exact rules appear in the Randoop source code in class CoveredClassTransformer.) +

+ +

+You can exclude additional packages from being transformed. +Create an exclusion file replacecall-exclusions.txt containing, for example: +

+
+mypackage.mysubpackage.
+org.something.library.
+
+

+and run the agent with the --dont-transform=filename command-line option: +

+
+-javaagent:${RANDOOP_PATH}/replacecall-4.3.4.jar=--dont-transform=replacecall-exclusions.txt
+
+ +

+The exclusion file is a list of package names, one package per line. +(Blank lines and //-style comments are ignored.) +If a package name does not end with a period, one will be added. +The package name is used to match the prefix of the fully-qualified classname. +

+ +

+For diagnostic output (such as to see what classes are being transformed), +run the agent with the --debug flag +

+
+-javaagent:${RANDOOP_PATH}/replacecall-4.3.4.jar=--debug
+
+ + + +

Defining replacements

+ +

+To define your own method replacements, you will write mock implementations (example) +and you will specify the replacements in a replacement file (example). +

+ +

+Each line of a replacement file is whitespace-separated package names +(replace all calls in all methods of all classes in the package and its +subpackages), or whitespace-separated class names (replace all methods in +the class), or whitespace-separated method signatures without return +types (replace the first method by the second). +

+ +

+Give the replacement file to the replacecall agent using the --replacement-file argument: +

+
+-javaagent:${RANDOOP_PATH}/replacecall-4.3.4.jar=--replacement-file=replacecall-replacements.txt
+
+ +

+ A replacement method must be static and non-private. + (Therefore, replacement classes don't need to be instantiated.) +

+
    +
  • If the original method is static, the replacement method should have the + identical signature.
    • +
  • If the original method is non-static, then the replacement method should +have an additional first parameter whose type is the containing +class of the original method. +For instance, a call to java.awt.Component.show() would be replaced +by a call to a method with the signature show(java.awt.Component). +An example mock class is +randoop.mock.java.awt.Component.
    • +
  • If the original method is a constructor (an +<init> method), +then the replacement method should have the same +parameter types, and its return type is the class that contains the +constructor. +
+ +

+Please keep in mind that when you define a replacement, +it can change the behavior of client code. +

+ + +

Tips about implementing replacement classes

+ +

+To simplify your replacement file and keep your mock classes organized, +you should choose a package prefix and keep the package +structure of the original classes. +Randoop's default replacements file uses randoop.mock as the prefix, so the +binary name of the JOptionPane mock class +is randoop.mock.javax.swing.JOptionPane. (You may need +to exclude this package if any +of the replacement methods use otherwise replaced methods.) +

+ +

+If the class containing the method you wish to replace is loaded by the bootstrap class loader, +or if it is called from a class loaded by the bootstrap class loader, then your replacement +classes must also be loaded by the bootstrap class loader. For Java 8 this list includes most +of the Java runtime. For Java 9+, the new module system dramatically reduces the number of +classes loaded by the bootstrap loader. +See Module base +for a list. If this condition applies to your replacement code +(assume it is located in myreplace.jar): +

+
    +
  • When running Randoop, add the additional command-line option to java: +
    +-Xbootclasspath/a:mypath/myreplace.jar
+
    +
    • +
  • When running the generated tests, add the file myreplace.jar to the boot class path: +
    +-Xbootclasspath/a:mypath/myreplace.jar
+
    +
    • +
+ +

+Randoop's default replacements are in sub-packages +of randoop.mock. You should not use +the randoop.mock prefix for your own mock classes. +

+ +

+Sometimes, a replacement for an instance method needs to access an object that +is different than the receiver (for example, it might have the same or a +different type than +the receiver). One way to manage this is for your replacement class to +maintain a map +from instances of the original receiver type to instances that will be used in +the replacement method implementations. +

+ + +

Specifying expected code behavior

+ +

+You can provide a specification of the expected behavior of code. Randoop will +use the specification to better classify method calls as error-revealing, +expected behavior, or invalid. +

+ +

+You can specify both the behavior of +methods and constructors, +and representation invariants for +classes. +

+ + +

Method specifications

+ +

+A specification of a method (including constructors) indicates the +circumstances when the method can be called, and how it should behave when +called. +

+ +

+The --specifications=file command-line option names a file +containing the method specifications. The file format is a JSON list with +elements that are the serialized form of +the OperationSpecification +class. You may also supply a .zip file containing such JSON files. +

+ +

+Randoop comes with an example +specification file, which provides specifications for +class net.Connection. +

+ +

+A method specification consists of the method signature, parameter names, a +list of pre-conditions, a list of (normal) post-conditions, and a list of +throws-conditions (exceptional post-conditions): + +


+  {
+    "operation": method-signature,
+    "identifiers": formal-parameters,
+    "pre": pre-condition-list,
+    "post": normal-post-condition-list,
+    "throws": throws-condition-list
+  }
+
+ +

+where only the operation field is required. +

+ + +

Method signatures

+ +

+A method signature uniquely describes a method. It consists of the +declaring class, method name, and parameter types. Types are given in the +format used +by Class.forName(); +for example, member classes are set off with "$", as +in pkg.Class$InnerClass. +

+ +

+The method net.Connection.send(int) +is represented as +

+ +

+  {
+    "classname": "net.Connection",
+    "name": "send",
+    "parameterTypes": [ "int" ]
+  }
+
+ +

+A constructor's name is the fully-qualified or simple class name. (The simple name contains no "." or "$".) +

+ + +

Formal parameter names

+ +

+The conditions in a specification use identifiers, or variable names, to +refer to formal parameters and the result. This part of the specification +gives the names. +For example: +

+ +

+  {
+    "parameters": [ "coded" ],
+    "receiverName": "target",
+    "returnName": "returnValue"
+  }
+
+ +

+indicates that the single formal parameter of the method is referred to by +the name coded. +The receiver name may be omitted (default: receiver), +and the return value name may be omitted (default: result). +

+ + +

Specifying conditions

+ +

+The specification contains 3 lists of conditions, one for each different +type of condition. +

+ +
+
Pre-condition
+
+

+ A pre-condition indicates a requirement that must be satisfied by + the caller. Its guard is a Boolean expression that is evaluated in the + pre-state — that is, before a method starts to execute. If the + caller does not satisfy the pre-condition, then the call is invalid. +

+ +

+ To specify that the argument to a call to net.Connection.send(int) + must be positive, you could write the condition +

+ + 

+    {
+      "description": "the code must be positive",
+      "guard": "coded > 0"
+    }
+
+ +

+ The condition has an optional field description + that Randoop uses in comments in the generated tests. +

+ +

+ To require that the Connection is open and the code is + non-negative, you could equivalently write a single + pre-condition receiver.isOpen() && code > 0 or + two pre-conditions receiver.isOpen() and code > + 0. +

+ +

+ A pre-condition is used to filter values, not to generate them. Randoop + uses a precondition to prune, not expand, its random search. +

+
+
+ +
+
(Normal) Post-condition
+
+

+ A post-condition indicates a requirement that must be satisfied by the method + implementation. A normal postcondition indicates what values the method + returns. If the caller satisfies the method's pre-condition and the method + returns normally (without throwing an exception), then the post-condition + must be satisfied or else the method is buggy. +

+ +

+ You specify a normal post-condition as guard-property pair. (A + property is given using the same format as a guard, but a property is + evaluated in the post-state — that is, after a method has + finished executing.) In the example file, the + method net.Connection.receive() has the post-condition: +

+ + 

+    {
+      "guard": "true",
+      "property": "result >= 0",
+      "description": "returns non-negative received value"
+    }
+
+ +

+ The guards of post-conditions are evaluated in the order that the + post-conditions are listed. The list +

+ + 

+    [
+      {
+        "guard": "!receiver.isOpen()",
+        "property": "result == -1",
+        "description": "if this is not open, return -1"
+      },
+      {
+        "guard": "true",
+        "property": "result >= 0",
+        "description": "otherwise, returns non-negative received value"
+      }
+    ]
+
+ +

+ indicates that the error-case should be tested first, followed by the + general case that has the vacuous guard true. +

+ +
+
+ +
+
Throws-condition
+
+

+ A post-condition indicates requirements that must be satisfied by the method + implementation. A throws-condition is a post-condition that indicates an + exception the method is expected to throw. If a call satisfies the guard of + a throws-condition, the exception must be thrown or the method is buggy. +

+ +

+ You specify a throws-condition as a guard-exception pair. + If a guard is satisfied, then the method is supposed to throw an exception + of the named class, or a subclass of the named class. + From the example file, the net.Connection.open() method has + the throws-condition +

+ + 

+      {
+        "guard": "receiver.isOpen()",
+        "exception": "java.lang.IllegalStateException",
+        "description": "throws IllegalStateException if the connection is already open"
+      }
+
+ +

+ Similar to normal post-conditions, throws-conditions are given in a list. + The list, however, is treated as a set (meaning unordered), and may contain + duplicate guards and exceptions. A method whose behavior is specified as +

+ + 

+      [
+        {
+          "guard": "a == null",
+          "exception": "java.lang.NullPointerException",
+          "description": "throws NullPointerException if a is null"
+        },
+        {
+          "guard": "i < 0",
+          "exception": "java.lang.IndexOutOfBoundsException",
+          "description": "throws IndexOutOfBoundsException if i is negative"
+        }
+      ]
+
+ +

+ is considered as correct if, when called with a==null and + i==-1, it throws either of the specified exceptions. +

+
+
+ + +

Evaluation rules

+ +

+Randoop classifies a test sequence according to its last method call. +

+ +
    +
  1. + If the guard of any pre-condition is violated before the call, then Randoop + classifies the method call as invalid and the sequence is discarded. +
    2. +
  2. + If the guard of any throws-condition is satisfied before the call, the + exception from the condition is added to a set expected of + expected exceptions. If the call throws a checked exception, the + sequence is classified as having expected behavior if the thrown + exception is a member of the set expected, or is a + subclass of a member of expected, and is otherwise + classified as error-revealing. If the expected set is + non-empty and the call terminates normally, the sequence is classified + as error-revealing. +
    3. +
  3. + If the guard of a normal-precondition is satisfied before the call, the + property for the first satisfied guard is checked after the call. + If the call terminates normally, the sequence is classified as having + expected behavior if the property is satisfied. + Otherwise, the sequence is classified as error-revealing. +
    4. +
  4. + If the method is inherited, the method call is also checked against all + specifications of overridden methods in the inheritance chain. + If the call is invalid by any specification, the sequence is classified + as invalid. + If the call is error-revealing by any specification, the sequence is + classified as error-revealing. + Otherwise, all specifications are satisfied and the sequence has + expected behavior. +
    5. +
  5. + Otherwise, the sequence is classified according to the + rules of classifying tests. +
    6. +
+ +

+Randoop does no check of whether the guards are exhaustive or disjoint. +

+ +

+Randoop ships with specifications for parts of the JDK, and these +specifications are used by default, unless you disable command-line option +--use-jdk-specifications. +

+ + +

Specifying representation invariant methods (such as checkRep)

+ +

+The "representation invariant" of a class is a property that all +instances of the class must satisfy. For example, a field might +contain a non-negative number, or two fields might contain lists of +the same length. +Sometimes, a program contains a method that checks the rep invariant, +for debugging purposes. +If the rep invariant is ever violated, the program has a bug. +

+ +

+By using the +@CheckRep +annotation, you can +tell Randoop which methods in your classes under test are rep +invariant methods. Randoop will call these methods; if the method +ever fails, Randoop outputs the test as a failing test. +

+ +

+A method annotated with @CheckRep must have one of two +allowed signatures: +

+ +
    + +
  • A public instance method with no arguments and return +type boolean. In this case, Randoop will interpret a return +value of true as the rep invariant being satisfied, and a +return value of false or an exception escaping the +method as the rep invariant being violated. +
    • + +
  • A public instance method with no arguments and return +type void. In this case, Randoop will interpret a normal return +(no exceptions) as the rep invariant being satisfied, and an +exception escaping the method as the rep invariant being violated. +
    • + +
+ + +

Testing a specific class or method

+ +

+ Randoop is designed to create tests for an entire project. This is + usually what engineers want. In rare cases, you might want to create + tests for a particular class or method. In general, it is better to run + Randoop on your entire project, and Randoop will create useful, broad + tests, including for the specific class or method. Randoop does not have + a way to generate tests for a specific class or method. However, you can + filter Randoop's output so that you only see some of its tests, using the + --require-covered-classes + or + --require-classname-in-test + command-line option. +

+ +

+ If you want to test a particular class or method, do not attempt + to use the --methodlist, --classlist, or + similar command-line options. They restrict the methods that appear + anywhere in a test, and are likely to lead to Randoop not producing any + output. +

+ + + +

Requiring tests to use a class: the covered-classes agent

+ +

+ Randoop generates tests that use methods, constructors, and fields of classes + given using the + --testjar, + --classlist, and + --testclass + options. + Any given test may involve one or more of the classes. +

+ +

+ The --require-covered-classes=filename + option makes Randoop discard any test that doesn't use at least one of the + classes listed in the file. +

+ +

+ Suppose you only want to test class A, but its methods takes arguments of type + B and C. If you supply only A as a test class, Randoop cannot create + objects of type B and C, so Randoop may be unable to call class A. Instead, + you can supply A, B, and C as test classes, but instruct Randoop to only + output the tests that use A. +

+ +

+ Use of the --require-covered-classes option is unusual: you + probably care about testing your entire application rather than just part of + it. The option makes Randoop less efficient, because Randoop creates but + discards tests. +

+ +

+ For the --require-covered-classes option to work, the classes + must be instrumented so Randoop can determine when they are covered. + You can do so by giving the following command-line + option for java +

+

+-javaagent:${RANDOOP_PATH}/covered-class-4.3.4.jar
+
+

+ This will instrument any non-abstract constructor and method of loaded + classes so that the use of a class can be detected. + The instrumentation is not done on any JDK or JUnit classes. + The covered-class-4.3.4.jar file can be found in the + unzipped distribution archive, or can be downloaded from the + latest release. +

+ + +

Specifying additional primitive values

+ +

+Randoop chooses arguments to method calls from the result of any previous +method call, and from a set of seed values. These are the built-in seed +values: +

+ +
    +
  • byte: -1, 0, 1, 10, 100
    • +
  • short: -1, 0, 1, 10, 100
    • +
  • int: -1, 0, 1, 10, 100
    • +
  • long: -1, 0, 1, 10, 100
    • +
  • float: -1, 0, 1, 10, 100
    • +
  • double: -1, 0, 1, 10, 100
    • +
  • char: '#', ' ', '4', 'a'
    • +
  • java.lang.String: "", "hi!"
    • +
+ +

There are two ways of specifying additional seed values to Randoop.

+ +
    +
  • Command line. +Use the --literals-file +and/or --literals-level +command-line option.
    • + +
  • Annotated code. Write the @TestValue annotation on a field. +The field should: + +
      +
    • include the @TestValue annotation,
      • +
    • be declared public and static,
      • +
    • be of a primitive (or String) type, or an array of primitives or Strings, and
      • +
    • be initialized to contain one or more seed values.
      • +
    + +You can write @TestValue +on a field in a class test, or you can create a helper class that just defines fields, and +include the class in the list of classes given to Randoop to test. + +

    Below is an example helper class that demonstrates the use of the +@TestValue annotation. For Randoop to use the primitive values +described in the class, you would add this class to the list of +classes under test +(e.g. via the option --testclass=example.TestValueExamples).

    + +
    +  package example;
+  import randoop.*;
+
+  public class TestValueExamples {
+
+    @TestValue
+    public static int i = 0;
+
+    @TestValue
+    public static boolean b = false;
+
+    @TestValue
+    public static byte by = 3;
+
+    @TestValue
+    public static char c = 'c';
+
+    @TestValue
+    public static long l = 3L;
+
+    @TestValue
+    public static float f = (float) 1.3;
+
+    @TestValue
+    public static double d = 1.4;
+
+    @TestValue
+    public static String s1 = null;
+
+    @TestValue
+    public static String s2 = "hi";
+
+    @TestValue
+    public static int[] a1 = new int[] { 1, 2, 3 };
+
+  }
+
    +
    • +
+ +

+ Randoop does not generate random string or primitive values. You can + include, as a method under test, a method that creates values. Its + output will be used as an input to methods in your code. +

+ + +

Nondeterminism

+ +

+Randoop is deterministic: if you run Randoop twice using +the --deterministic +command-line argument, Randoop outputs the same tests in the same order. +

+ +

+If you want Randoop to produce different test suites, +run Randoop twice supplying +different values for the +--randomseed command-line argument. +This is the recommended practice, to yield an overall test suite with better coverage. +

+ + +

Finding the source of nondeterminism

+ +

+If Randoop produces a different output when you run it twice with +the --deterministic +command-line argument, then there is some source of nondeterminism. + +

+If Randoop produces flaky tests +and --flaky-test-behavior +is not set to HALT, Randoop will output a list of methods suspected to be the +cause of nondeterminism in decreasing order of likelihood. You should +investigate these methods, fix nondeterministic ones or exclude them +via --omit-methods +or --omit-methods-file +command-line argument, and re-run Randoop until flaky tests are not generated. +

+ +

+If you discover a nondeterministic method, open an issue so the Randoop +maintainers can include it in Randoop's +default omitmethods-defaults.txt +or JDK-nondet-methods.txt. If Randoop suggests as flaky a method +that you know is deterministic (for example, a JDK method), then open an issue +so the Randoop maintainers can include it in the nonFlakyMethods +list. +

+ +

+The remainder of this section gives several reasons you may discover. +

+ + +

Nondeterministic program under test

+ +

+If the program under test is nondeterministic, Randoop may +produce different tests on different runs. More seriously, +Randoop may produce flaky tests that sometimes +pass and sometimes fail. +

+ +

+If the program under test is nondeterministic, you have several options: +

+ +
    +
  1. +Change the program to be deterministic. +In addition to making the program more testable, this is likely to make the program easier to debug. +Here are some ways to eliminate nondeterminism in a sequential Java program: + +
      +
    • + Hashing. Even if your code does not call hashCode() + directly, it may be nondeterministic if some hashCode() + method is deterministic. +
        +
      • + Object.hashCode() depends on where the object is laid + out in memory, which depends on the operating system and on when + the garbage collector runs. Most classes + should equals() (the default is reference equality), + and any class that overrides equals() must + override hashCode(), for consistency + with equals(). +
        • +
      • + Object.toString() depends + on Object.hashCode(). Most classes should + override Object.toString() to give more informative + output (and usually not to depend on the hash code). +
        • +
      • + Arrays.deepHashCode() depends on + on Object.hashCode(). +
        • +
      • + For determinism, don't instantiate the Object class, + as in new Object(); instead, use some class that overrides + Object.hashCode(). For + example, DeterministicObject + returns a number indicating the creation order of the object. +
        • +
      • + Some collections have arbitrary iteration order, such + as HashMap and HashSet. Either sort + their results, or replace the data structures by + LinkedHashMap + and + LinkedHashSet. +
        • +
      +
      • +
    • + Some APIs produce results in arbitrary order, such + as File.list() + and File.listFiles(). + Sort their results before using them. +
      • +
    • + Don't call new Random() without an argument. Instead, use + (for example) new Random(0). +
      • +
    • + Don't use time and date functions to obtain the current time. +
      • +
    +
    2. + +
  2. +Transform the program at run time to make changes like the ones above, replacing +the method's behavior with a different implementation +(such as a deterministic one or a mock). +You can do this by using +Randoop's replacecall agent. +
    3. + +
  3. +Prevent Randoop from directly calling problematic methods. +Use the --omit-methods +or --omit-methods-file +command-line argument. +
    4. + +
  4. +Instruct Randoop to attempt to discard or repair any flaky tests that it +generates. +Use the +--flaky-test-behavior +command-line argument. +This is a last resort because Randoop may output a small test suite due to +discarding many of the generated tests. +When possible, is better to avoid generating flaky tests +rather than discarding them after generating them. +
    5. +
+ +

+You can also see the techniques suggested in the paper +Scaling Up Automated Test Generation. +

+ + +

Changes to the program or its environment

+ +

+If the program or its environment changed between runs, Randoop may produce +different test suites.. +

+ +

+Changing the JDK counts as a change to the program. +For example, consider a class +

+
+public class Corner extends JComponent { ... }
+
+ +

+In JDK 7, Corner's getAccessibleContext method is +inherited from JComponent. +In JDK 8, Corner's getAccessibleContext method is +inherited from java.awt.Component. +Depending on the JDK in use, Randoop discovers a different set of operations, +because Corner.class.getMethods() returns different results +depending on the JDK. Given different sets, Randoop may make different +choices and produce different tests. +

+ +

+There can be implementation changes even within a single JDK major version, +such as two different versions of JDK 8. These differences can lead to +different Randoop outputs, or to tests that passed on one JDK +implementation but fail on another. +

+ + +

Debugging nondeterminism in Randoop

+ +

+If the above techniques don't help you, you can +diagnose nondeterminism by running Randoop twice +with the command-line options +

+
+  --deterministic --log=randoop-log.txt --selection-log=selection-log.txt
+
+

+Compare the logs across runs, and the first place +that they differ will help you find the nondeterminism. +

+ +

+If you find that Randoop is +nondeterministic because of a bug in Randoop, +please report it so that we can investigate +and correct the problem. +

+ + +

Getting help

+ +

You can get help on Randoop in the following ways:

+ +
    +
  • Manual: what you are currently reading.
    • + +
  • Randoop's help command: For help on + usage, use Randoop's help command. To print Randoop's main help message, run: + +
    java -classpath ${RANDOOP_JAR} randoop.main.Main help
    + +To print help for a command (such as gentests or minimize), supply it: + +
    +java -classpath ${RANDOOP_JAR} randoop.main.Main help gentests
+
    + + +
    • +
  • Mailing list: If you don't find your question answered, + email either randoop-discuss@googlegroups.com or + randoop-developers@googlegroups.com (never both) with your + question. (You might not see your question on the mailing lists + immediately, because your message may need to be approved.) + If your question relates to an execution of Randoop, be sure to give enough + information to reproduce the execution; see the instructions for + submitting a bug report. +
    • +
  • Bug reporting: If + you have discovered a problem with Randoop, we would like to fix it. + Please see the instructions for submitting + a bug report. +
    • +
+ + +

Troubleshooting

+ +

Randoop does not run

+ +

+ If the command to run Randoop has the output +

+
+Cannot find or load randoop.main.Main
+
+

+then Randoop is not properly included in the classpath. +One possibility is that you have included the Randoop jar file in the path +specified by the CLASSPATH variable, but have given the location of +the classes-under-test with the -classpath option at the command line. +In this case, the java command will only use the classpath from +-classpath. +

+ +

+It is recommended that both Randoop and the classes under test be included as +the argument to the -classpath option to the java command. +It only makes sense to set CLASSPATH to run Randoop if the location +of classes-under-test will be the same each time you run it. +See the Java Tutorial on +path and classpaths. +

+ +

+ If the command to run Randoop has the output +

+
+Cannot find the Java compiler. Check that classpath includes tools.jar
+
+

+ then there is a problem with your Java installation. + You perhaps have the JRE on your path before the JDK. + Ensure that JAVA_HOME appears at the front of your path. + If you run the Windows operating system, see the + + instructions for setting a custom Java path. + Another possible cause of the problem is using an unsupported version of Java. +

+ + +

Randoop cannot find a class-under-test

+ +

+ If when Randoop is run, something like the following is output +

+
+No class found for type name "example.ExampleClass"
+
+
+Unable to load class "example.ExampleClass" due to exception: java.lang.ClassNotFoundException
+
+
+MyClass was read from myjar.jar but was not found on classpath.  Ensure that myjar.jar is on the classpath.
+
+

+ then the classes under test are not in the classpath. + The most likely case is that you have not included the path to these classes. + Another possible cause is that you did not supply the classpath to Randoop properly. +

+ +

+ As described in the "Running Randoop" section, a typical invocation is +

+
+    java -classpath myclasspath:${RANDOOP_JAR} randoop.main.Main ...
+
+ +

+ If you are running Randoop on Windows, parts of the classpath should be + separated by a semicolon ";" instead of the colon ":" shown in the examples + in this document. + See the Java Tutorial on + paths and classpaths + for platform-specific information on paths. +

+ + +

Randoop does not create enough tests, or creates no tests

+ +

+if Randoop's generated tests do not cover some part of your code (or if +Randoop outputs "No tests were created. No JUnit class created."), then you +need to change Randoop's parameters and re-run it. Spending just a little +bit of effort may have a big impact on the quality of Randoop's output. +

+ +

+Consider some specific method that Randoop does not call, and determine why +Randoop does not call that method. Run Randoop +with logging +enabled. Here is an incomplete list of possible problems and +solutions: +

+
    +
  1. + The method is not a candidate to be called by Randoop. Randoop creates + a "model", or a list of methods that it might call. This list appears + in the Randoop logs after the text "Operations:". If the method is not + in that list, determine why. Two common reasons are that the method (or the + class that defines it) is not public or that it is excluded by + an --omit-methods or + --omit-methods-file + argument (or the default omissions). +
  2. + Randoop never tries to call the method. That is, Randoop never + randomly selects this method, from among all the methods in the model. + You should run Randoop with a + larger timeout. Alternately, you could run Randoop with fewer classes, or exclude some + classes or methods from consideration. You might also + avoid using + --usethreads, which can make Randoop run very slowly. +
    3. +
  3. + Randoop tries to call the method, but is unable to create inputs (arguments to the method). + You should give Randoop more classes to analyze, namely + ones that create the objects that the method needs as input. +
    4. +
  4. + Randoop calls the method, but the inputs it uses are not valid/useful inputs. + You should investigate why Randoop is unable to create the needed + inputs. Maybe you need to give Randoop more classes to analyze (as in the previous bullet point) or + provide additional primitive values. +
    5. +
+ +

+If Randoop gets stuck, it outputs +"*** Randoop has spent over 10 seconds executing the following test.", +but it does not output any tests. +Randoop creates and executes one test at a time, so +a long-running sequence will prevent Randoop from creating new tests. +Two possible reasons for a long-running test are: +

+
    +
  • Randoop is executing a test that contains nonterminating behavior, + or that takes very long to execute. + See "Randoop does not terminate". +
    • +
  • + Java has run out of memory and is thrashing. + This explanation is likely if Randoop had become progressively slower + before getting stuck; examine + Randoop's progress output to see + if this + is the case. + Give Java more memory by running java with, + say, -Xmx3000m. +
    • +
+ + +

Randoop does not terminate

+ +

+When Randoop does not terminate, that is usually because Randoop is creating +tests that do not terminate (or that execute for a very long time). +You have two options. +

+
    +
  • + Determine which method in which test is the problem, and give Randoop + information about that method so that Randoop will not call it in + long-running ways or not call it at all. +
      +
    • To determine the problematic method, do one of these: +
        +
      • Use + the --log=filename + command-line option, and the currently-executing test should be at the + end of the file. +
        • +
      • Examine the stack trace. + Use the jstack + command, which you can run as jstack pid. + Get the process id by running jcmd. + (On Unix you can also type Ctrl-\; that is, hold down the + Control key, then press the Backslash key.) A method that appears + in multiple such stack traces may be the problem. +
        • +
      • Run Randoop with command-line option + --usethreads, and with logging + enabled. + Examine the logs, which report which methods were terminated + because they ran for too long. +
        • +
      +
      • +
    • + Fix a bug in the method, or prevent calls to the method using one of these techniques: + +
      • +
    +
    • +
  • + Run Randoop with the command-line option + --usethreads=true. + This will cause Randoop to discard tests in + which any directly-called method takes + too long to run. +
    • +
+ + +

Randoop produces different output on different runs

+ +

+See the manual section on nondeterminism. +

+ + +

Randoop generated flaky tests

+ +

+A test is flaky if it behaves differently on different executions. +

+ + + +

+There are two main reasons for flaky tests. One is global side effects: a +Randoop-generated test might call a method that sets a static field or +creates/deletes a file. (Calling Randoop on a method that side-effects +local state, such as a field of the receiver or of an argument, is fine.) +Another reason is nondeterminism: the program under test might behave +differently on different runs. Such behaviors are not appropriate for in +unit tests, so you should not call Randoop on such methods. +

+ +

+If Randoop encounters a flaky test, Randoop halts so that you +can correct your invocation of +Randoop. Another section of the manual +gives steps for determining the source of +nondeterminism. +

+ +

+If you find a flaky test that does not result from side effects or +nondeterminism in the program, then please help us improve Randoop by +submitting an issue via the +issue +tracker. + +

+ + +

Randoop produces a regression test suite that does not pass

+ +

+Randoop outputs regression tests that passed during test generation. If +the regression tests fail when you run them, they are said to be flaky. +This is due to nondeterminism in the program under test. +See the manual section on nondeterminism. +

+ + +

Tests behave differently in isolation or when reordered

+ +

+Another symptom of calling Randoop on methods that have global side effects, in +addition to flaky tests, is +dependent +tests: tests that behave differently depending on whether some other +test has already run. For instance, test B might succeed if run after test +A, but fail if run on its own. +

+ +

+You have two choices. (1) Always run Randoop's generated tests in the same order +(without performing test selection, prioritization, or parallelization). +(2) Avoid calling Randoop on methods with global side effects as +described in the section on flaky tests. +

+ +

+Another possible symptom is that if you run Randoop's tests and then your +original test suite, the original test suite might fail because of side +effects performed by Randoop's tests. +To avoid this problem, you can run Randoop's tests in a separate JVM, or +run Randoop's tests last, or avoid calling Randoop on methods with global +side effects as described in the section on flaky +tests. +

+# A fatal error has been detected by the Java Runtime Environment:
+#
+#  SIGSEGV (0xb) at pc=0x00007f925c9f2320, pid=28883, tid=0x00007f922dfc9700
+#
+
+

+This indicates that a segmentation fault has occured within the Java Runtime Environment. +This almost always is caused by a bug in the JRE --- it should never crash. There are two +potential ways to work around this problem: +

+
    +
  1. + Try using a newer version of Java if one is available. + We have seen this problem most often with JDK 8. +
    2. +
  2. + When this fault occurs, the Java Runtime will produce a core dump. Try looking at the + stack trace in the core dump to determine the test class that led to the fault, then use + one of the Randoop options to remove this class from consideration by Randoop. +
    3. +
+ + + + + + + + + +

Reporting a bug to the issue tracker

+ +

+ If + you have discovered a problem with Randoop, we would like to fix it. + Please submit an issue to the + issue tracker. + (Before doing so, search the open issues and the manual, especially the + Troubleshooting + section.) +

+ +

+ You should include enough information to + enable the Randoop developers to reproduce the problem, which will make + it easier for them to diagnose the problem, fix Randoop, and verify the + fix. This generally includes +

+ +
    +
  • the version of Randoop (please use the most recent released version, + or the current version from the + GitHub version control repository),
    • +
  • the exact commands you ran (please use the -ea option to + java when running Randoop, which makes diagnosis easier),
    • +
  • the complete output of the commands, and
    • +
  • all the files that are necessary to run the commands.
    • +
+ +

+ Never submit just a screenshot or image of your computer screen. + Instead, cut-and-paste the text of your command and its output. The text + is easier to read, is searchable, and does not require transcribing from + a screenshot in order to reproduce. +
