Why is it important to design test cases in accordance with the established test areas?

Designing test cases in accordance with established test areas is vital to ensure comprehensive testing coverage. Test areas are defined during the test planning phase and serve as a structured approach to identify and delineate the parts of the application that require testing. By aligning test cases with these areas, the test team can systematically cover all aspects of the application, including functionality, performance, security, and compatibility.

Comprehensive testing coverage helps in identifying potential defects that might otherwise go unnoticed, especially in complex systems. It reduces the risk of overlooking critical components, which could lead to significant issues once the product is in production. Moreover, this approach enables stakeholders to have a clearer understanding of what has been tested and allows for better risk management by ensuring that all relevant functionalities are assessed.

While other options may touch on relevant aspects of the testing process, they do not capture the primary purpose of aligning test cases with established test areas as effectively as ensuring comprehensive coverage does.
