What is UI tests?

UI tests, also known as User Interface tests, are automated tests that verify the functionality and visual aspects of an application's user interface. They simulate user interactions with the UI, such as clicking buttons, entering text, and navigating between pages, to ensure that the application behaves as expected and the UI elements are displayed correctly. UI tests are commonly used to validate the end-to-end functionality of an application, catch visual defects, and ensure a consistent user experience across different browsers and devices. They are typically more complex and slower to execute compared to unit tests, but they provide a higher level of confidence in the overall quality of the application.
