OfficialDesign test coverage that matches risk
System Documentation
What problem does it solve?
It prevents under-testing and misaligned effort by translating acceptance criteria into the right mix of Unit, Integration, and E2E coverage while explicitly documenting risks, gaps, and targets.
Core Features & Use Cases
- Maps acceptance criteria to test levels using clear behavioral types and an adjacent-level strategy to capture both domain correctness and real boundary behavior.
- Expands each AC with mandatory scenario coverage, including known errors, edge cases, idempotency/replay behavior, and dependency failure modes.
- Defines measurable coverage expectations per tier (minimum coverage and mutation score), plus concrete tooling/fixtures/resources and a structured output artifact for the workflow.
Example use case: when building a refund flow (POST endpoint with idempotency), the skill produces a plan that covers domain rules, repository/integration behavior, and the cross-service/data persistence path—while calling out what E2E UI will be intentionally deferred.
Quick Start
Ask an AI to generate a Gate-ready test plan for your feature’s acceptance criteria and persist it to .ahrena/issues/{n}/02b-test-plan.md.
