What type of testing is focused on determining how easy the software product is to understand and use for the user?

Usability testing is specifically designed to evaluate how easy and intuitive a software product is for the user. It focuses on aspects such as the user interface, user experience, and overall satisfaction with ease of use. During usability testing, participants typically perform tasks while observers note any difficulties or confusion they encounter. The goal is to identify areas where the software might not meet the user's expectations or needs, improving the overall user experience.

This type of testing emphasizes user interaction and feedback, helping developers understand how real users interact with the system. Insights gained from usability testing can lead to design improvements that enhance user satisfaction and effectiveness.

In contrast, functional testing verifies that the software performs its intended functions correctly without focusing on user experience. Regression testing checks whether new code changes affect existing functionalities, and integration testing assesses how well different software modules work together. These other types of testing primarily focus on system behavior and correctness rather than user-friendliness.
