QA backend logic: design and run unit, integration and edge-case tests for services, jobs, database code and business rules. Use when asked to test a backend change, find bugs in a service, or raise test coverage where it matters.
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
# Backend QA Aim tests at the rules that cost money or data when they are wrong, not at coverage numbers. 1. **Read the change and its callers.** List the rules it must enforce and the invariants it must not break. 2. **Choose the level.** Pure logic gets unit tests. Anything involving the database, queue or transaction gets an integration test against the real engine the project uses, not a mock of it. 3. **Cases to cover for each rule:** the normal case, boundaries (0, 1, max, empty, null), duplicates and retries (is it idempotent?), concurrent callers, ordering, time and timezone edges, and partial failure (the second write fails after the first succeeded). 4. **Money, auth and deletion paths** get the most cases: wrong user, wrong tenant, expired or revoked credentials, double charge, undo. 5. **Write the failing test first** when you suspect a bug, watch it fail for the right reason, then report it or fix it as asked. 6. **Run the project's existing suite** with its own command and report real output. Do not mark anything passing that you did not run. ## Report …

How to install
mdr add thameema/memnos/qa-backend@sha256:a3be5d90ee0efc46The line at the top of this page pins the label git:20261028.22056eb, 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.
