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

The correct choice refers to a test case, which is specifically defined as a set of input values and execution preconditions that are used to fulfill a specific test objective. A test case encompasses all the necessary information that defines how the test should be executed, including what inputs are needed, the expected results, and any specific conditions that must be met before the test is run.

Test cases are crucial in an Agile environment as they provide a structured approach to validating that software features work as intended. By clearly laying out the input conditions and expected behaviors, test cases help ensure that testing is thorough and that the software meets the specified requirements. They serve as a guide for testers to follow when executing automated or manual tests.

On the other hand, a test condition refers to a situation or aspect of the software that can be tested, not the specific inputs and preconditions needed for execution. Test data pertains specifically to the data used in tests, which is only one part of a test case. Test design encompasses the overall strategy and methodology for creating tests, but it does not directly refer to the specifics of the inputs and conditions defined in a test case.
