We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

React Native — Geração de Testes

Objetivo

Produzir testes significativos para código existente, cobrindo comportamento e bordas.

Quando utilizar

  • Código novo ou legado sem cobertura.
  • Completar lacunas antes de refatorar.
  • Adicionar testes exigidos por regra (repositório, hook, mapper, helper, util, UI).

Conhecimentos necessários

  • Padrões de teste do projeto (ver skill rn-testing).
  • Identificação de casos: caminhos, ramos, bordas e erros.
  • Estratégia de mocks e isolamento por camada.
  • Queries de acessibilidade para UI.

Fluxo de execução

  1. Leia a unidade e liste comportamentos observáveis e ramos.
  2. Enumere casos: sucesso, erro e borda (null/undefined/vazio/limite).
  3. Monte mocks das dependências (rede, store, navegação, nativo) antes dos imports.
  4. Escreva 3–5 testes focados por arquivo em Arrange/Act/Assert ("should").
  5. Rode, verifique a cobertura dos ramos relevantes e ajuste.

Boas práticas

  • Teste comportamento observável, não implementação.
  • Um assert conceitual por teste; nomes descritivos.
  • Reutilize fixtures/factories de dados de teste.
  • Prefira poucos testes de alto valor a muitos triviais.

Armadilhas comuns

  • Gerar testes que só espelham a implementação.
  • Cobertura alta sem asserts significativos.
  • Esquecer ramos de erro e bordas.
  • Mocks frágeis acoplados a detalhes internos.

Critérios de sucesso

  • Ramos e bordas relevantes cobertos.
  • Testes falham quando o comportamento quebra.
  • Suíte verde, determinística e sustentável.
