Try a sample question
Which statement best characterizes a low-level (concrete) test case as distinguished from a high-level (abstract) test case?
- It specifies concrete preconditions, input data, expected results, and postconditions.
- It indicates only which test conditions are covered, with no concrete data.
- It can never be derived from a high-level test case.
- It must always be executed by the person who authored it.
Show answer and explanations
Correct answer: A. It specifies concrete preconditions, input data, expected results, and postconditions.
Explanation
A low-level (concrete or physical) test case is the detailed refinement of a high-level test case: it states specific preconditions, input data, expected results, and postconditions. A high-level (abstract or logical) test case only indicates which test conditions are covered, without concrete values.
Why each option
- Correct. A low-level test case gives concrete preconditions, input data, expected results, and postconditions.
- Indicating only the covered test conditions with no data describes a high-level (abstract) test case.
- Low-level cases are typically refinements derived from high-level ones, not unrelated to them.
- Any tester may execute a test case; authorship does not restrict who runs it.
