Functionality testing can be an extremely useful tool when testing a software application. However, just as with any QA testing method, it is best for certain situations. Here we discuss when you should apply a functional test to your software application:
When you’re testing a specific feature
Functionality testing is performed best when you have a limited scope. In other words, if you want to test a specific feature or an individual piece of your application, functionality testing is the way to go.
If you’re asking yourself “does it work?”
The purpose of functionality testing is to check the functions of your application. It makes sure that every part of your software is working as it should. So, if you’re implementing a new feature and asking yourself “does it work?”, then you need to perform a functionality test to answer that question.
If you need to check that your application is accessible
There are actually many different types of functionality tests. One of those types is accessibility testing. This checks to make sure that all individuals can use your product, and that your software follows Section 508 requirements from the Workforce Rehabilitation Act of 1973.
