Integration test philosophy -- test observable behavior, fixture composition, canary markers for library internals.
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
# Testing Philosophy ## Integration Tests Verify Behavior, Not Internals Integration tests must verify **observable behavior through endpoints**, not implementation details. **Good integration tests:** - Drive endpoints with an HTTP client - Assert status codes and response bodies - Verify side effects (emails sent, database rows created, audit entries logged) - Test cross-cutting concerns (middleware, auth, rate limiting) **Bad integration tests:** - Calling internal service functions for behavior already observable via HTTP - Using DB queries as the primary assertion surface (DB is for post-assertion verification) - Testing internal query functions or utility functions -- those belong in unit tests - Duplicating coverage already exercised by another test ## Prefer Fixture Composition If a test starts with boilerplate setup (register a user, log in, configure a setting), that belongs in a fixture. Test bodies should stay focused on what they're actually testing. Build fixture stacks: `user` -> `logged_in_user` -> `admin_user`. Each level adds one concern. Tests request the level they need. ## Canary Markers for Library Internals …

How to install
mdr add jartan-llc/grimoire/testing-patterns@sha256:57b9cd891ba9c6a8The line at the top of this page pins the label git:20260807.010f635, 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.
