What Is Functional Testing Software?

[EvelynLopez]

I’m trying to understand what functional testing software is and how it works. Could someone explain its purpose, key features, and why it’s important in software development?

Functional testing software verifies that a program's features and functions work correctly according to the required specifications. It focuses on what the system does from an end-user's perspective (black-box testing), ensuring that all inputs yield the expected, correct outputs.

Functional testing software is used to make sure that applications perform as required.
Examples include:

Selenium

QTP/UFT

TestComplete

Ranorex

They are used to check on UI, API and business logic.
