What are Functional Testing Tools for Azure DevOps?

Functional testing tools are software platforms designed to verify that a system or application performs as expected according to its functional requirements. These tools automate the process of testing individual features and functionalities of an application to ensure they work correctly. Functional testing tools typically support a variety of testing types, including unit testing, integration testing, and user acceptance testing (UAT). They allow testers to simulate user interactions with the application, execute test cases, and identify bugs or issues in the functional behavior of the software. By automating repetitive testing tasks and improving accuracy, functional testing tools help accelerate the software development lifecycle and ensure high-quality releases.
