Functional Testing and Non-functional Testing – What’s the Difference?

Software testing is broadly divided into functional and non-functional testing, each serving distinct purposes to ensure a flawless software application. Functional testing focuses on verifying that each feature of the software conforms to user requirements, using techniques like smoke, sanity, integration, regression, and localization testing. This type of testing is crucial to validate the software's actions and is generally executed before non-functional testing to establish a stable foundation. Non-functional testing, on the other hand, assesses parameters such as performance, security, and usability, meeting customer expectations through methods like performance, usability, and security testing. Both testing types are essential to deliver a defect-free product, with automation tools like testRigor enhancing the efficiency of the quality assurance process by allowing comprehensive testing without the need for coding skills.
