Define or implement regression proof: test strategy, black-box or integration tests, KPIs, thresholds, audits, or missing tests.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Create test

Start with the user need or business rule that must always hold, not files, coverage, or internal calls.
Inspect for facts; ask only for business decisions that cannot be discovered.

## Definition of done

Agree on the observable result, the oracle that decides correctness, and exact checks before implementation.
Record the environment, data, expected result, unchanged behavior, and limits of the checks.
Use existing checks where they provide evidence. Ask for business rules and acceptance criteria that the evidence cannot settle.
For a bug, reproduce the failure. For new behavior, use agreed examples and show the acceptance check fails before the change.
For a refactor, keep the characterization baseline green before and after the change.
Record each intended behavior difference with its reason and a concrete before and after.

## Define the regression contract

Establish:

- actors, goals, and externally observable outcomes;
- business rules and invariants that must never change;
- critical paths and relevant rejection, timeout, retry, permission, concurrency, and partial-failure cases;
- the current baseline and every intended behavior change;

How to install

The exact contents, by fingerprint
mdr add reidemeister94/development-skills/create-test@sha256:90e95f41bf8abff6

The line at the top of this page pins the label git:20261031.a82a617, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
