This is a type of testing to ensure software applications will perform well under their expected workload. A software application’s performance like its response time, reliability, resource usage and scalability do matter. The goal of Performance Testing is not to find bugs but to eliminate performance bottlenecks.
The focus of Performance Testing is checking a software program’s
Speed – Determines whether the application responds quickly.
Scalability – Determines maximum user load the software application can handle.
Stability – Determines if the application is stable under varying loads.
