PERFORMANCE TESTING
Functional Testing evaluates individual and cohesive behaviour functions of a software system to verify that they adhere to pre-defined specifications. It tests the functional accuracy, interoperability of subsystems and compliance with pre-defined standards in the context of functional and business requirements. Performance testing is a non-functional testing technique that exercises a system and then, measures, validates and verifies the response time, stability, scalability, speed and reliability of the system in production-like environment.
