What is a Functional Tester?

A Functional Tester is a quality assurance professional dedicated to verifying that a software application performs exactly as intended according to its functional requirements and specifications. This role meticulously examines each feature and function of the software to ensure it meets user needs and business objectives.

Unlike a Performance Tester who focuses on system speed and stability, or a Security Tester who identifies vulnerabilities, a Functional Tester's primary goal is to validate that the software behaves correctly from a user's perspective. They ensure that all buttons work, data inputs are handled accurately, and workflows follow the defined logic, playing a critical role in delivering a reliable and user-friendly product.
