  7. Non functional testing may be performed at all test levels. The term non-functional testing describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale, such as response times for performance testing.

    Types of Non-functional testing are performance testing, load testing, stress testing, usability testing, maintainability testing, reliability testing and portability testing.
