# Design Tests Stage — Elaboration

## Criteria Guidance

### Good criteria — concrete and verifiable

- "Test suite spec includes test cases for every requirement with traceability matrix linking tests to requirements"
- "Each test case has explicit preconditions, steps, expected results, and pass/fail criteria"
- "Automation feasibility assessment identifies which tests to automate, which to run manually, and the rationale"

### Bad criteria — vague (no clear check)

- "Test cases are designed"
- "Automation is planned"
- "Tests are ready"
