APPLICATION AND DECISION GUIDE
Prompt Test Case Matrix Builder: method and usage
Builds a repeatable test-matrix draft from a task, desired behavior, and risk areas, separating success criteria, expected behavior, and human-review notes. It does not call a model, execute tests, or provide security certification.
an instruction with an explicit goal, audience, context, constraints, and expected output format Confirm the shape first with a small example containing no personal data.
an editable prompt draft, coverage metrics, and explicit improvement actions
Practical steps
- Enter the task and one desired behavior or risk area per line.
- Generate the local matrix and edit each expected behavior.
- Run cases against the real model/version and record observed outcomes and reviewers.
model testing with representative normal, missing-context, conflicting, sensitive-data, and prompt-injection cases
Rule-based review does not prove real model behavior; retest with representative cases.
Suitable use cases
- Preparing prompt regression sets
- Surfacing boundary and abuse cases
- Planning human evaluation
