Functional Testing Vs Performance Testing
- Functional Testing: Functional testing is conducted to verify the correctness of the operations of the software. The features and functions are tested before performance testing. The purpose is to verify that the internal operations of the product are working according to desired specifications. Functional testing typically tests accuracy of the application and how it behaves with different operating systems.
- Performance Testing: Performance Testing is designed to test the overall performance of the system at high load and stress conditions. Performance Testing occurs through out the software development life cycle to isolate performance related constraints. Even at unit level, the performance of the individual module may be assessed as the internal logic of software that is being tested.
