Which of the following is not considered a type of non-functional testing?

Usability Testing
Accessibility Testing
Unit Testing
Reliability Testing

The correct answer is: Unit Testing

Unit testing is primarily concerned with verifying the functionality of specific components or units of a software application. This type of testing focuses on ensuring that individual parts of the code work as intended, which is a functional aspect of testing. In contrast, non-functional testing evaluates criteria that are not related to specific behaviors or functions of the system. This includes factors like usability, accessibility, and reliability, which measure how well the software performs under various conditions rather than what specific functions it performs. Usability testing assesses how user-friendly and intuitive an application is, accessibility testing verifies that the software is usable by people with disabilities, and reliability testing measures the software's ability to consistently perform its required functions under expected conditions over time. These all fall under the umbrella of non-functional testing. Therefore, unit testing stands apart as a functional testing practice.
