Usability Tests are a very helpful tool that can be used to find usability errors in an application. It is highly important for the developers to find out the usability errors in the software product. The tool mainly checks whether the application is user-friendly, useful, and traceable by comparing it with the designed vision of the product. Usability testing is the process of observing how people interact with a product or service under specified circumstances. In this process, a moderator asks users to interact with the software, which also checks for error messages and traceability systems.
