How to use JMeter for load testing

What you will need

  • Apache JMeter
  • A running web application
  • Browser of your choice

Load Test Process

Start Apache JMeter and record the test script. Let’s create a test plan that we will execute for our load test. As part of this post, I will be load testing login to a Spring boot based web application that I am running at https://localhost:8443/home

Create a test plan

Once you launch JMeter, on left hand side window you will see an option for test plan. Create a test plan and let’s name it Test1 as shown below:

Add Config Elements

Right click on test plan and add config elements for HTTP Cache Manager and HTTP Cookie Manager. This is required for handling CSRF tokens in our request that we will need later.

Add a Sampler

Now to test our web application, we will add a sampler with HTTP Request. We will name this HomePage. This is displayed as below:

Add a Listener

Now we will add a listener to our sampler to view results as a tree.

Add a Post Processor

We will need _csrf token from our home page so we can pass this token in POST request to login page of web application.

Add another Sampler for Login Page

Now we will add Sampler for Login Page which will be a POST request to login endpoint of our web application. We will also pass username and password along with _csrf token whose value will be populated from extractor.

Run the test script for load test

Now if we run our script in JMeter, it will run 50 threads at the same time to test login for application. Depending on performance, it might take a long time, but considering this a simple application, JMeter will run this test within few seconds.

Review the results

Once the test is complete, you can check the View Results Tree and it will show you the results of our each individual test thread. In Response Data tab, you can view if our test was successful or not. It should show the result of our page in html format.


In this post, we used Apache JMeter for load testing and how it can help us to design our application from performance perspective.
