Functional Testing is a type of software testing that focuses on verifying if a system behaves as expected according to its requirements. It checks the functionality of the software by testing various features and ensuring they work correctly. This type of testing often involves using test cases that cover different scenarios, including user interactions and system responses, to confirm that the software meets its intended purpose. During Functional Testing, testers evaluate specific functions of the software, such as user interfaces, APIs, and database interactions. By identifying any defects or issues, this testing helps ensure that the software delivers a seamless experience for users and meets quality standards before it is released.
