Load Testing with Apache JMeter.

Now that we have learnt about the difference between Siege and Apache JMeter in the previous article, it’s time to talk about running basic HTTP api load tests with JMeter.

JMeter is a pure Java application and should run correctly on any system that has a compatible Java implementation.

One can download and install apache JMeter from here.

Open it and let’s get started. You’ll see an empty Test Plan as below.

Test Plan is where you can describe the name of your tests and add comments about it. We’ll keep the name Test Plan for the sake of reference.

Right click on the Test Plan and add Thread Groups as shown below:

A Thread Group is where you specify the number of users that you want to simulate. One thread = one user.

Number of threads: It is where you specify the number of users that you want to simulate. One thread = one user.

Ramp Up Period: By setting the ramp-up period, you can also tell JMeter how long it should take to reach all of the threads that you’ve chosen.
