Functional testing is a critical aspect of the software development process, particularly within Agile methodologies. Its primary purpose is to evaluate whether the software's functionality corresponds to the specified requirements. In an Agile environment, where development is iterative, functional testing occurs frequently and is designed to assess the features delivered in each iteration or sprint.

By focusing on the specific functions of the application, functional testing ensures that new features work as intended and that any requirements set for the iteration have been met. This type of testing may involve a variety of techniques, including user acceptance testing, integration testing, and system testing, all aimed at confirming that the software behaves correctly from an end-user perspective.

In contrast, performance testing is concerned with how well the software performs under various conditions but does not specifically assess functional aspects. A/B testing is typically used to determine which of two options performs better, usually in the context of marketing or user experience, rather than assessing functionality against requirements. Regression testing aims to ensure that previously developed and tested features continue to work after changes, but it is a broader check rather than a focused assessment on newly delivered functionality.
