What is a Functional Testing Tool?
A functional testing tool works as a helper for computer programs. When people make computer programs, they need to test them. That they find out if there’s any error or issue with their programs.
Now, this tool checks if every part of the program does what it’s supposed to. Now, there are also functional automation testing tools. These are special because they can test programs automatically without someone having to do it manually.
For example, if there’s a button that should open a new page, the tool makes sure it does that on its own. It acts as your assistant who tries out all the features and tells you if something’s wrong.
So, in simple words, whether manual or automated, these tools make sure everything in a computer program works fine. They help catch mistakes and fix them before others use the program.
How Best Functional Testing Tools Can Help Your Software Development?
In the sprawling landscape of software development, quality assurance stands tall as the guardian of user experience and functional precision. Central to this domain are functional testing tools.
