Functionality testing is a critical component in quality assurance testing. It makes sure that your application performs as advertised once it is released onto the market. However, what is it about functionality testing that makes it stand apart from the rest? What makes a test a functionality test to begin with? Here we provide you with the answers:
What is functionality testing?
Simply put, a functionality test focuses on the functions of your product. It ensures that an application works as advertised, checking that each feature performs properly. A functional test, then, is all about what a product does. It validates basic usability and accessibility so that the user receives a well-functioning product at the end of testing.
There are many types of functionality tests, including the following:
- Smoke testing
- Unit testing
- Black box testing
- Regression testing
- Sanity testing
- Integration testing
- White box testing
- Accessibility testing
Functional testing vs. Non-functional testing
Most quality assurance tests can be lumped into one of two categories: functional tests and non-functional tests. A functional test is all about the actual function—or, making sure that a feature actually works. A non-functional test, meanwhile, is about how those functions perform. This includes such things as reliability, speed, efficiency, and more.
