An Ideal Software testing process has to be a holistic approach that involves combination of various testing techniques to achieve a high quality software. Broadly speaking, testing of any application can be broken down on the basis of two premises – “Operability” and “Efficiency”. “Operability” is taken care of by functional testing and “Efficiency” is taken care of by 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.
In this article, we will assess the differences between Performance and Functional testing.
On close observation of the above table, it can be noticed that both the testing types complement each other. Performance testing validates that application software can handle real time scenarios and address issues, if any, to deliver a robust and efficient product to the end users. Functional testing company on the other hand ensures the validity of software as per the functional and business requirements.
To have a win-win situation at hand, where resources and efforts are optimized and a comprehensive testing is performed, it is imperative to combine both functional and performance testing. This will ensure that a stable, reliable and functionally robust software is delivered to the customer.
Webomates has optimized testing by combining our patented multi channel functional testing with performance testing where the same functional tests can be used for load testing. Our regression testing service not only guarantees full regression of every test case (even modified ones) within 24 Hours but also provides triaged defects with video, screenshots and log artifacts.
