Test Case Review

Test Case Review is a systematic examination of test cases to ensure they are correct, complete, clear, and aligned with requirements before execution.

Test case review answers: “Are our test cases good enough to find defects?”

1. Definition

Test Case Review is a systematic examination of test cases to ensure they are correct, complete, clear, and aligned with requirements before execution.

2. Purpose of Test Case Review

  • Identify defects in test cases early
  • Improve test coverage and quality
  • Ensure requirement traceability
  • Reduce rework during execution
  • Prevent missed scenarios

3. When Test Case Review Is Performed

  • After test case design
  • Before test execution
  • When requirements change
  • During test readiness reviews

4. Who Participates in Test Case Review

  • Testers (peer review)
  • Test Lead / QA Lead
  • Business Analyst / Product Owner (optional)
  • Developers (for complex logic)

5. What to Review in Test Cases (Checklist)

5.1 Requirement Coverage

  • Each requirement mapped to test cases
  • No missing scenarios

5.2 Clarity & Correctness

  • Clear steps and expected results
  • No ambiguity

5.3 Test Design Quality

  • Proper use of EP, BVA, decision tables
  • Positive, negative, and edge cases covered

5.4 Independence & Reusability

  • Test cases are not dependent on each other
  • Reusable where possible

5.5 Data & Preconditions

  • Test data clearly defined
  • Preconditions mentioned

6. Manual Tester’s Role

  • Participate actively in peer reviews
  • Provide constructive feedback
  • Update test cases based on review comments
  • Ensure reviewed test cases are approved

7. Test Case Review vs Test Case Execution

Aspect Test Case Review Test Case Execution
Goal Improve quality Validate functionality
Timing Before execution After build
Outcome Refined test cases Pass/Fail, defects

8. Benefits of Test Case Review

  • Early defect detection
  • Better test coverage
  • Reduced execution issues
  • Higher testing efficiency

9. Common Mistakes

  • Skipping reviews due to time pressure
  • Superficial reviews
  • Not documenting review feedback
  • Ignoring negative scenarios

10. Interview-Ready Answers

Short answer:

Test case review is the process of evaluating test cases to ensure quality and completeness before execution.

Detailed answer:

Test case review helps identify gaps, ambiguities, and errors in test cases early, improving testing effectiveness and reducing rework.

11. Key Takeaway

Test Case Review ensures test cases are defect-free before they are used to find defects.
