Frontend testing rules with Vitest, React Testing Library, and MSW. Includes coverage requirements, test design principles, and quality criteria. Use when writing frontend tests or reviewing test quality.
Language-agnostic testing principles including TDD, test quality, coverage standards, and test design patterns. Use when writing tests, designing test strategies, or reviewing test quality.
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
Use when testing PRPM CLI commands locally - provides build, environment setup, execution workflow, contract testing to verify documented behavior matches implementation, and comprehensive cross-format conversion testing against local registry
TDD方法論に従ってテストを作成します。テスト対象コードの分析、AAA/Given-When-Thenパターンの適用、正常系・エッジケース・エラー系のカバレッジを確保します。「テストを書いて」「テストを作成」「単体テストを追加」などのリクエストで起動します。
