Software Quality Assurance Practice Exam

Presentation layer testing involves which of the following activities?

1. Checking business logic

2. Testing human-interface elements

3. Verifying database connections

4. Ensuring security protocols

The correct answer is: Testing human-interface elements

Presentation layer testing focuses specifically on the user interface and user experience aspects of a software application. This involves evaluating how the system’s graphical elements, such as buttons, forms, and navigation menus, perform and respond to user interactions. The objective is to ensure that these human-interface elements function correctly, appear as intended, and provide an intuitive experience for users. Testing in this layer may include verifying that the layout is consistent across different devices or browsers, checking the functionality of input fields, ensuring that visual elements are displayed correctly, and validating that error messages provide clear guidance when users make mistakes. The emphasis is on usability and the overall interaction between the user and the application, which is central to presentation layer testing. Understanding this focus is key because other activities like checking business logic, verifying database connections, and ensuring security protocols pertain to different levels of testing, such as backend or integration testing, which concentrate on the underlying systems rather than the user-facing interface.
