What is the primary focus of a test case?

The primary focus of a test case is to verify compliance with requirements. A well-structured test case is designed to ascertain whether a specific feature or behavior of the application under test meets the specified requirements and expectations. This involves checking that the application behaves as intended for given inputs and conditions, thereby ensuring that it aligns with what the stakeholders have defined as necessary functionality.

The construction of a test case often includes detailed instructions on how to perform the test, expected results, and actual results to make it clear whether pass or fail criteria have been met. However, the ultimate goal remains to ensure that the tested aspect complies with the outlined requirements, thereby providing assurance of quality and functionality.

While defining a test environment, detailing specific execution postconditions, and outlining conditions for testing are all important aspects of the testing process, they are secondary to the fundamental purpose of validating whether the software meets the needs that it was developed to address. These elements contribute to effective testing but do not encapsulate the primary objective of a test case itself.
