As the name itself indicates, it is basically a test that is done to make sure what sort of performance an application offer when the same is made run under a load which is more than what it can actually handle or tolerate. Here it really doesn’t matter what type of function and the features are supported by the software under concern. One of the main aims in this testing is not to find the errors that affect the functionality but to find parameters that can enhance the performance of the app. This is how it is different from any other testing technique. The other name of this testing is Perf Testing.
