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.

Functional testing software is a tool used to verify that an application’s features work according to specified requirements. It simulates user actions, checks inputs and outputs, and validates workflows. These tools help identify defects, ensure reliability, and confirm that each function performs correctly before release, improving overall software quality and user experience.

The software to functional testing is the software used to test software (or applications) to ensure that everything works in a proper manner: do inputs make the software do the correct thing, make the user interface features to do the expected thing, and work processes flow properly. It assists developers and testers in detecting issue or bugs in a product prior to its release.

Functional testing software checks whether an application performs its intended functions correctly. It validates user interactions, workflows, inputs, outputs, and system behavior against requirements. These tools help ensure reliability, usability, and proper feature performance before deployment.
