So many types of testing!!...and whats now.. Soak testing?? Some one asked me this question during an Interview..I was like "Which testing???" :-)
Soak Testing is a type of testing where we run the application or system at high level of load for prolonged period of time. This type of testing is needed to verify the memory leaks* in the application. Load testing and stress testing may not find such issues because the time duration for stress and load testing is very less.
*Memory leaks: It is the accumulation of the memory resource by the application and not releasing it after its use. This may result in breaking down of the application.
