4. Non functional testing describe the performance or usability of the software system.
5. This kind of testing is carried out by performance specifications
6. Examples of Non functional testing examples 1.Volume Testing 2.Scalability 3.Usability Testing 4.Load Testing 5.Stress Testing 6.Compliance Testing 7.Portability Testing 8.Disaster Recover Testing
