+# Harness of Node.js
+
+## Build addons
+
+To build the addons, run the following command:
+
+```bash
+$ npm run addons:configure
+$ npm run addons:build
+```
+
+## Running tests
+
+Run the following command to run the tests:
+
+```bash
+$ npm run node:test
+```
+
+To run a specific test file, use the `--test-name-pattern` flag:
+
+```bash
+$ NODE_OPTIONS=--test-name-pattern=js-native-api/test_constructor/test_null npm run node:test
+```
+
+The test names are their relative path to the `tests` folder, with file extensions.
+The pattern can be a regular expression.
