How to Write Test Cases
sign in to trackA well-written test case is precise, reproducible, independent, and unambiguous. It tells any competent tester exactly what to do, what data to use, and what the expected outcome is — without requiring prior knowledge of the feature.
◈Key Points
- Anatomy of a test case: ID, Title, Preconditions, Steps, Test Data, Expected Result, Actual Result, Status.
- Each step should have one action and one expected result — avoid compound steps.
- Write expected results in terms of observable behaviour, not internal system state.
- Test cases should be independent — no test should depend on the result of another.
- Apply equivalence partitioning and boundary value analysis to reduce the number of cases needed while maximising coverage.
⚡ Expert Pro Tip
Read your test cases aloud as if explaining them to someone who has never used the software. If you stumble, the case needs rewriting.
