JMeter - Test Plan (JMX file)

A test plan describes a series of steps JMeter will execute when run.

A test plan will consist of one or more:

• Thread Groups,
• Logic controllers,
• Sample generating controllers,
• pre-processor
• post-processor
• Listeners,
• Timers,
• Assertions,
• visualizer
• and configuration elements.

To be able to re-run the same test with different different parameters, you have the following possibilities:

• to define a set of variables on the Test Plan, and then use those variables in the test elements. For example, one could define the variable LOOPS=10, and refer to that in the Thread Group as ${LOOPS}. To run the test with 20 loops, just change the value of the LOOPS variable on the Test Plan.
• define a property or a property file.
