- Get your test plan peer-reviewed before moving forward.
What is a “Test Case”?
A Test Case is a specific set of conditions or variables under which a tester will determine whether an application, software system, or one of its features is working correctly or not. A Test Case aims to validate software features’ accuracy, completeness, and reliability. A test case usually includes the following details:
- Test Case ID.
- Test Case Description.
- Module [Optional].
- Use Case ID or User Story ID [Optional].
- Pre-Condition.
- Test Steps.
- Test Data.
- Expected Results.
- Post-Conditions.
- Actual Results.
- Status (Passed or Failed).
