What is Performance Testing

o Act of testing or evaluating software or a component or hardware for its conformance with

the performance testing goals and optimizing its performance . It is about testing the

application with the intent to identify the application stability.

o Performance testing is a subset of Performance Engineering which aims at building

performance into the design and architecture of the system, prior to the actual coding effort.

It helps in building the application that meets the performance requirement from therequirement phase.

o Performance testing is carried out to measure:

Responsiveness of the system

Stability

Scalability

Assess likelihood of positive feedback

Assess adequacy of infrastructure4

What is Performance Testing (contd.)

To assess configuration of the system hardware

System breakpoint

o Pre-requisite for Performance Testing is that the system should be functionally stable and

code changes should be freezed .
