What is a well-formed test case?

• A. A test case is simply a title.
• B. A test case includes objective and input only.
• C. A test case lists steps and expected results without context.
• D. A test case includes a title, objective, input conditions, steps, expected result, acceptance criteria, and preconditions.

Answer: (D)

A well-formed test case is a complete, structured recipe for verifying a specific requirement. It should clearly identify what is being tested (title), explain why it’s being tested (objective), describe the initial state or data (input conditions and preconditions), outline the exact actions to perform (steps), specify the expected outcome (expected result), and define the criteria that determine success (acceptance criteria). This combination ensures the test can be run consistently by anyone, in any environment, and the result can be judged unambiguously against a standard. Without preconditions or acceptance criteria, tests can drift into different states or interpretations; without steps and expected results, the actions and outcomes aren’t repeatable or verifiable. A title alone or only partial details won’t provide the clarity needed for reliable testing.
