What are Free UI Testing Tools?

UI testing tools are software tools that are used to test the user experience of a website or application. These tools focus on testing the functionality, usability and overall look of the user interface from the point of view of an end-user. They are designed to assess whether or not users can navigate the website or app in an intuitive way, check for any bugs or glitches, and verify that all functionality works as expected. UI testing tools come in many different forms including manual tests, automated tests and load tests; most often they offer a combination of these methods in order to provide comprehensive results. Furthermore, many teams choose to use both local and cloud-based UI testing tools to ensure complete coverage across a range of devices and operating systems.
