Scalability Testing is part of
non-functional testing. It's an ability of
network,
process or a system to continue to function well. Its also a kind of
performance testing, where tester focus on application behaviour while testing the application under excessive load. The purpose of performing
scalability testing is to identify the reason where the application stops responding or adapting to the changes.
