What a good test case should achieve
A test case should help another qualified person understand what is being validated, under what conditions, using which data, and what result determines pass or fail.
Good cases are repeatable without becoming excessively procedural.
Recommended test case structure
| Field | Purpose |
|---|---|
| Title | Describe behaviour or condition being validated. |
| Traceability | Link to story, AC, requirement, risk, or feature. |
| Preconditions | Environment, role, setup, state, or dependency. |
| Test data | Specific data needed. |
| Steps | Actions required to exercise the scenario. |
| Expected result | Observable result that determines pass/fail. |
| Priority / risk | Importance to release and regression planning. |
Write useful titles
Weak
Test login
Better
Successful login with active user and valid credentials
Write expected results that can fail
Weak expected result
“System works correctly.”
Better expected result
“User is redirected to the dashboard, the account name is displayed, and an authenticated session is created.”

Classify tests for reuse
Useful metadata includes priority (P1/P2/P3), suite (smoke/sanity/regression), test type, automation status, and requirement mapping. This turns a flat repository into a maintainable coverage model.
