Software Quality Assurance Practice Exam

What type of testing focuses on how easy a system is for users to operate?

1. Function testing

2. Usability testing

3. Integration testing

4. Regression testing

The correct answer is: Usability testing

Usability testing concentrates on evaluating a system's user-friendliness and overall experience for the end user. The primary goal is to identify how easily users can navigate and utilize a product to accomplish their tasks, ensuring that the interface is intuitive and aligns with user expectations and needs. This type of testing often involves real users performing tasks in a controlled environment while observers note any difficulties or points of confusion. In contrast, function testing assesses whether the software performs its intended functions correctly, integration testing verifies that different components of the software work together as expected, and regression testing ensures that new code changes do not adversely affect existing functionalities. While all these testing methods are crucial for software quality assurance, usability testing specifically zeroes in on the user's experience and ease of interaction, which is why it is the correct choice in this context.
