Design, implement, repair, or review automated tests for observable behavior, regressions, contracts, stateful boundaries, and flaky failures. Use when testing is a primary part of the request or when choosing test levels, isolation, fixtures, or reliability requires dedicated judgment. Do not use merely to run existing checks after an ordinary implementation.

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

# Superior Testing

Make tests provide durable evidence about behavior and risk. Fit the suite to the repository's existing tools and architecture; do not impose a generic test pyramid, framework, or coverage target.

## Establish the contract

Before writing a test, identify:

- the observable behavior or invariant being protected;
- the failure or regression the test must distinguish;
- the public boundary where the behavior can be observed;
- dependencies, state, time, concurrency, and external systems involved;
- existing test conventions, helpers, fixtures, and CI constraints.

For a reported bug, reproduce the failure before changing the implementation when practical. Confirm that the test fails for the intended reason rather than because the fixture, environment, or assertion is broken.

## Choose the narrowest credible test

Read [references/test-strategy-and-levels.md](references/test-strategy-and-levels.md) when selecting among unit, component, integration, contract, end-to-end, property-based, or migration tests, or when a change needs coverage at more than one layer.

Prefer the least expensive test that exercises the real owner of the risk:

How to install

The exact contents, by fingerprint
mdr add kodekateam/superior-skills/superior-testing@sha256:b40a517a36336939

The line at the top of this page pins the label git:20261015.f413813, 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.
