Q: What testing approaches can you tell me about?
A: Each of the followings represents a different testing approach: black box testing, white box testing, unit testing, incremental testing, integration testing, functional testing, system testing, end-to-end testing, sanity testing, regression testing, acceptance testing, load testing, performance testing, usability testing, install/uninstall testing, recovery testing, security testing, compatibility testing, exploratory testing, ad-hoc testing, user acceptance testing, comparison testing, alpha testing, beta testing, and mutation testing.
Q: What is stress testing?
A: Stress testing is testing that investigates the behavior of software (and hardware) under extraordinary operating conditions.
For example, when a web server is stress tested, testing aims to find out how many users can be on-line, at the same time, without crashing the server. Stress testing tests the stability of a given system or entity.
Stress testing tests something beyond its normal operational capacity, in order to observe any negative results. For example, a web server is stress tested, using scripts, bots, and various denial of service tools.
