Which tests should include reviews of all user interfaces?

User interface tests are specifically designed to evaluate the functionality, usability, and overall experience of the user interfaces within an application or system. These tests focus on how users interact with the software, ensuring that all components, buttons, forms, and navigational elements perform as expected and provide a positive user experience. By including reviews of all user interfaces, the tests can verify that the system is intuitive and meets user requirements, making this choice the most appropriate for the question.

In contrast, unit tests primarily target individual components or functions of the software without concern for user interactions. Integration tests examine how different modules or components work together but do not specifically focus on the user interface. Physical interface tests generally assess hardware interfaces or physical connections, which are not relevant to the review of software-based user interfaces. Thus, the focus on user interfaces within user interface tests makes this choice the clear and correct selection for the question.
