JMeter Tutorial: Overview of JMeter

Apache JMeter is an Open Source tool used for performance testing. It comes under Apache project with Apache License 2.0.  It is purely based on java and can be used for non functional testing, functional testing for some scenarios (e.g. registering of form with different users), and regression testing and so on.

It was developed by Steffano Mozzachi at Apache software Foundation.

It supports various protocols which are mentioned in the below diagram:
