What is defined as a set of input values and execution preconditions for a specific test objective?

The correct answer is the definition of a test case. A test case is a formalized document that outlines a specific set of input values, execution preconditions, and the expected outcome to assess a particular test objective. It provides a clear framework for testers to follow, ensuring that they evaluate the system's functionality according to predetermined criteria.

In agile testing, a well-defined test case can help in verifying whether the software meets the requirements and behaves as expected under various conditions. This level of detail is crucial for identifying defects and ensuring that all aspects of the software are thoroughly tested.

In contrast, a test condition refers to a specific aspect or requirement that needs to be verified during the testing process, but it does not provide the same structured approach as a test case. Test data encompasses the actual values used within the test case, while test design generally pertains to the overall strategy or approach for testing, which may include the creation of multiple test cases based on different test conditions and scenarios. Thus, a test case serves as a fundamental building block in the testing process, enabling structured and effective evaluation of the software.
