How does JMeter's execution work?

JMeter is a powerful open-source tool for the Performance, Load, and Stress testing of web applications. To fully understand its potential, it's important to know the order in which JMeter's executions work.

While executing a test plan in JMeter, it follows a specific execution order:

• Configuration Element

• Pre Processor

• Timers

• Samplers

• Post Processor

• Assertions

• Listeners

The execution order within a controller is sequential, from top to bottom. If there are multiple samplers within a controller, then they will be executed in the order in which they appear in the test plan.

A thorough understanding of the execution order in JMeter is crucial for designing an effective and well-structured test plan and a well-structured test plan ensures accurate performance test results and identifies areas for improvement in web applications for better performance.
