📖 What is Functional Testing?

Functional Testing is a type of testing that evaluates the functions a system should perform. It focuses on 'what' the system does, verifying that its behavior aligns with specified functional requirements.

🥋 Sensei Says:

"Remember that functional testing can be performed at all test levels. Don't confuse it with system testing, which is a test level, not a test type."
