Coverage-design method for qa-engineer — pyramid ratios per archetype, equivalence/boundary/property case selection, mutation score as the real coverage signal, and a flake-quarantine policy. Turns "coverage is 90%" (a number with no method) into a defensible test plan. Emits TEST-STRATEGY-{slug}.md, which the QA gate checks exists.
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
# test-strategy
Coverage % is a number with no method. This skill makes the QA plan defensible:
**what** to test, **why** that set, and a **real** signal that the tests bite.
qa-engineer emits `docs/qa-reports/TEST-STRATEGY-{slug}.md` capturing the four
decisions below; the QA gate checks the file exists for medium/large features.
## 1. Pyramid ratio — pick by archetype (not by reflex)
The right unit:integration:e2e mix depends on where the risk lives.
| Archetype | unit | integration | e2e | why |
|-----------|------|-------------|-----|-----|
| library / devtools / cli | 80% | 15% | 5% | logic-dense, few I/O seams |
| web-app / saas | 60% | 30% | 10% | request→db→render seams dominate |
| commerce / fintech / marketplace | 50% | 35% | 15% | money paths need cross-component proof |
| data-platform / streaming | 45% | 45% | 10% | correctness lives in pipelines, not units |
| ai-system / agent-product | 50% | 20% | 10% + **evals 20%** | behaviour is the contract → eval set (see [[decision-eval]]) |
State the chosen ratio in TEST-STRATEGY and justify any deviation.
## 2. Case selection — equivalence / boundary / property
Don't enumerate inputs; **partition** them.

How to install
mdr add avelikiy/great_cto/test-strategy@sha256:08be541661d2de68The line at the top of this page pins the label git:20260628.6eab4d5, 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.
