ServiceNow Performance Engineering | JMeter

Testing REST ServiceNow APIs using JMeter offers a powerful approach to validate the functionality and performance of the ServiceNow platform. Leveraging JMeter, a test scenario has been created to evaluate API endpoints, authentication mechanisms, data retrieval, and overall system responsiveness. JMeter identifies potential bottlenecks and performance issues by simulating real-world user interactions and load conditions, enabling teams to fine-tune the APIs for optimal efficiency. With its flexibility and ability to generate insightful reports, JMeter is an indispensable tool in ensuring the reliability and scalability of REST ServiceNow APIs, enhancing the overall user experience and boosting the platform's capabilities.

This is a step-by-step guide to test the performance of ServiceNow APIs.

How to Conduct the Performance Testing

The performance testing involves the following APIs:

API Label	ServiceNow API	Documentation link	Method	Parameters
Incident Table	api/now/table/incident	incident API	GET	0
sys_user1	api/now/table/incident	incident API	GET	1
sys_user2	api/now/table/incident	incident API	GET	2
sys_user3	api/now/table/incident	incident API	GET	3
post_user	api/now/table/incident	incident API	POST	0

Run the test (Method 1)

This method is simple since you can use the shell file provided to run all the commands needed. The only requirements are that homebrew is installed. After installing homebrew, open a terminal and follow the steps below.

1. Clone this repository

git clone https://github.com/TarasZhere/ServiceNow-performance-engineering-JMeter.git

2. cd the folder

cd ServiceNow-performance-engineering-JMeter

3. Start the script

sh startup.sh

4. Wait 15 minutes for the report

Just wait for the time required to run the test (15 min), and as soon as the test is done, a folder report will appear in the directory with inside a .html file displaying the complete report of the examination.

Run the test (Method 2)

1. Download the JMX file to perform the test

Download JMX File or clone the repository with the provided ServiceNow.jmx with git clone https://github.com/TarasZhere/ServiceNow-performance-engineering-JMeter.git

2. Install JMeter

Use the command (in order) to install the software using homebrew. brew install jmeter

or reference the original documentation @ JMeter.com

3. Run the test

jmeter -n -t < path of ServiceNow.jmx from this repository> -l < path of where you want to store the resulting file>/ServiceNow.csv -e -o < path to the output folder. (It must be an empty folder)>

example: jmeter -n -t ./ServiceNow.jmx -l ./ServiceNow.csv -e -o ./report/

4. Wait 15 minutes for the report

Just wait for the time required to run the test (15 min), and as soon as the test is done, the report will appear in the directory you chose inside a .html file having a complete report of the examination.
