Use when unit-testing a CQRS command or query handler against in-memory fakes, or when writing one of those fakes — this skill owns `tests/unit/fakes/`, so a request for a fake repository or a fake `ICan<Verb>` capability lands here rather than on either adapter-test skill. Also covers failure injection through an inline `_RaiseXxxRepository` subclass, and the test that a failed side effect after the store write leaves the command succeeded. Not the real adapter against a real backend…
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
# Hex Test — Application Handler (unit) Consult `test-principles` for the testing constitution. Where this skill contradicts `test-principles`, the constitution wins. Produces one unit-test file per handler module. Runs in milliseconds against in-memory fakes. Coverage targets the happy path plus every domain exception the handler propagates and — for compensating-transaction handlers — the post-failure undo, and, where a side effect follows the store write, a failed effect that leaves the command succeeded. ## When to use vs. neighbours - A new or modified handler under `application/<subdomain>/`, or a fake it needs under `tests/unit/fakes/` → this skill (write the fake first). - A fake for a capability port (`ICan<Verb>`) as much as for a repository (`IFooRepository`) → this skill; it owns both, which is why a bare "write me a fake" lands here and not on an adapter-test skill. - One-off failure injection for a single handler test → this skill — declare a `_RaiseXxxRepository(FakeFooRepository)` subclass at the handler test module scope instead of extending the fake. …

How to install
mdr add wntic/pyhouse/hex-test-application-handler@sha256:daa1a0836c9a47b7The line at the top of this page pins the label git:20261011.7949974, 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.
