Functional Testing

Functional testing is a core practice in software quality assurance that verifies whether an application’s features work as intended. It ensures that the software performs specific functions according to business requirements, user stories, or development specifications – focusing strictly on what the system does, not how it’s built internally.

Functional software testing helps identify critical issues such as incorrect calculations, broken workflows, or missing functionality. It ensures that the core actions of your application – like logging in, submitting forms, or processing transactions – behave correctly under various conditions.
