The execution order of the elements in an Apache JMeter performance test plan is very important, it helps understand the timeline of events and how your test will behave.

Make sure that you understand every JMeter element before adding it to your test plan, this will help create faster performance tests and not jump into various errors. Creating tests with JMeter can be tedious at the beginning, but as you start learning more and more about each of the elements and which are the required one, the time invested in creating test scripts will decrease. More details on how Apache JMeter works.

You can also use a Chrome Extension to click and record all your domains and API requests automatically, no coding skills needed with Record and Run Chrome Extension from LoadFocus.

This will automatically save your JMeter test in the cloud from where you can run JMeter tests in the cloud with more than 10k concurrent users per test from multiple world locations.

To test APIs or websites that use Auth, you can checkout our article on How to Test OAuth Secured APIs & Apps using JMeter.

Below is the ordered list, have in mind that some of the elements are optional.


  1. Configuration elements
  2. Pre-Processors
  3. Timers
  4. Sampler
  5. Post-Processors
  6. Assertions
  7. Listeners
