In this video, Mike Smith illustrates the importance of listeners, sections of the JMeter load test that visualize the results from the load test.
- If I wanted to run my test right now…all I would really need to do is click on the start button…on the toolbar, and the load test…would perform a test as outlined.…However, I set up the actions that the load test…need to perform, but I have no real way of knowing…if the test has been successful or not.…To do this, I'll need to add a listener.…Listeners give JMeter a way of displaying the results…of a test as it's running.…
Now for larger tests, this isn't recommended,…because displaying the output live during the load test…can use a lot of system resources.…But for small tests like this and for a test creation,…it's absolutely fine.…Plus, I want to know if my test actually works,…so I'll need to add at least one to verify this.…If I right click on the test plan…instead of the thread group and highlight listeners,…I can see a long list of listeners that I can add…to the project including some of the additional…graph plugins I added earlier.…
I'm going to add the view results tree into my test plan…to see the basic results of my load test.…
