If you are new to JMeter and performance testing then refer the post below:

🔴What is JMX script and why we need it ?

🚀JMX scripts are used in performance testing to simulate user behavior and generate load on the application, enabling testers to measure its performance under different conditions.

🚀JMX scripts consist of various elements such as thread groups, samplers, controllers, listeners, and timers.

🚀Thread groups represent a group of virtual users that will simulate load on the application.

🚀Samplers are used to simulate requests made by virtual users, while controllers are used to define the flow of requests.

🚀Timers can be used to introduce delays between requests.

🔴How to create JMX script from JMeter?

Here are the steps to create a JMX script to test www.reqres.in with 100 users:

🚀Open JMeter and create a new Test Plan.

🚀Right-click on the Test Plan and select Add > Threads (Users) > Thread Group.

🚀In the Thread Group, set the following properties:Number of Threads: 100

Ramp-Up Period: 10 (this means that each user will be started with a delay of 100ms between them)

Loop Count: 1

🚀Right-click on the Thread Group and select Add > Sampler > HTTP Request.

🚀In the HTTP Request sampler, set the following properties:

Name: Reqres Request

Protocol: http

Server Name or IP: www.reqres.in

Path: /api/users?page=1

🚀Right-click on the HTTP Request sampler and select Add > Listener > View Results Tree.

🚀Save the Test Plan as a JMX file.

🚀This script will send a GET request to www.reqres.in/api/users?page=1 with 100 concurrent users and capture the response using the View Results Tree listener. You can customize this script by adding additional samplers, modifying the request properties, or adding more listeners to capture specific metrics.
