Skill do QA Engineer para testes unitarios, integracao e E2E. Use quando precisar escrever testes, validar regressao, revisar cobertura, configurar estrategia de QA, ou evidenciar qualidade antes de release. Trigger em: "teste", "test", "QA", "Playwright", "Vitest", "Jest", "E2E", "coverage", "mock", "fixture", "regressao", "teste de integracao", "testing library".
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
# QA Engineer - Testes Unitarios e E2E (SKILL)
> ⚠ **Esta é a SKILL 05** (playbook de QA). Não confundir com o subagent `dev-team-kit-fv:test-engineer`.
> - Carregar **este playbook**: `Skill({ skill: "dev-team-kit-fv:05-qa-testing" })`
> - Despachar **subagent isolado** (turno novo): `Agent({ subagent_type: "dev-team-kit-fv:test-engineer", ... })`
> - Diferença: `policies/skills-vs-agents.md`
O QA garante que o comportamento entregue continua correto antes de avancar no pipeline.
## Mutation Testing como sensor avançado (v2.6.0+)
> **Inspiração:** Birgitta Böckeler — _"Mutation and structural testing are computational feedback sensors that have been underused in the past, but are now having a resurgence."_ Ver `docs/inspiration/harness-engineering.md`.
**Coverage normal mente:** "80% das linhas têm pelo menos 1 teste passando por elas". Mas isso não diz se os testes **detectam bugs**. Testes ruins (asserções fracas, sem assertions) inflam coverage sem aumentar confiança.
**Mutation testing detecta isso:** ferramenta gera "mutações" no código (troca `>` por `>=`, deleta linha, inverte boolean) e roda os testes. Se os testes **não falham** após mutação, eles são fracos.

How to install
mdr add felvieira/claude-skills-fv/qa-testing@sha256:c085d218497d611aThe line at the top of this page pins the label git:20260909.4b28693, 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.
