Functional testing is an essential type of testing that focuses on verifying that each function of the software application operates in conformance with the required specification. This type of testing is designed to ensure that the software behaves as expected under normal operating conditions. During functional testing, testers evaluate user interfaces, APIs, databases, security, client/server applications, and mobile devices to ensure that the software responds correctly to a variety of inputs and conditions defined in the requirements.

By concentrating on expected conditions, functional testing validates the core functionalities of the software. It aims to answer the question of whether the software does what it is supposed to do according to the functional requirements specified.

Other types of testing, while important, serve different purposes. Stress testing evaluates the software's behavior under extreme conditions, aiming to identify the point at which the system fails. Load testing assesses the application's performance under anticipated user loads but does not focus on whether specific functionalities are working as intended. Integration testing primarily examines how different modules or components of the application interact with each other, rather than the correctness of individual functions on their own.
