Unit test

Skill HsuanYuLee/polaris/.claude/skills/unit-test

Project-aware unit testing guide with mock patterns, TDD discipline, and best practices. Auto-detects test framework (Jest/Vitest) and provides appropriate examples. Use when: (1) writing or fixing unit tests, (2) user says "寫測試", "write test", "補測試", "add test", (3) user encounters mock patterns or test failures, (4) user asks how to test a composable, component, or store, (5) user says "mock imports", "test store", "怎麼測", "測試怎麼寫", (6) reviewing test quality: "unit test review", "review tests", "check test quality", "測試審查", "review 測試", "測試品質", "檢查測試品質", (7) TDD workflow: "TDD", "test driven", "紅綠燈", "先寫測試", "test first", "red green refactor".From its SKILL.md

Unit Test

unit-test 是 project-aware unit testing guide，用於寫測試、修測試、review test quality， 或在 engineering 中執行 TDD。

Contract

測試要驗證真實行為，不用 mock-only assertions 製造假綠燈。明確 TDD 時採 red / green / refactor；一般補測試時仍要先確認現有 framework、local patterns、test command。

Flow

  1. Detect test framework and repo-specific test command.
  2. Locate existing tests near the target module and copy local style.
  3. Decide whether strict TDD applies using tdd-smart-judgment.md.
  4. Plan test cases from simplest to most complex.
  5. In TDD mode, run one red/green/refactor cycle per case.
  6. In non-strict mode, write focused tests alongside implementation.
  7. 先跑 narrow test command，再跑 owning workflow 要求的 broader command。
  8. Report changed tests, command results, coverage gaps, and any intentional non-testable scope.

Hard Rules

  • 不可為了 pass 而弱化 assertions、加入 .skip()、刪 tests、或加 type suppressions。
  • Public behavior 可測時，不測 private implementation details。
  • 不 inline 大量 mock data；改用 fixtures 或 factories。
  • 除非 dependency boundary 需要，不用 mock 取代 real source logic。
  • 每個 test 驗證一個 behavior；需要用 "and" 命名時通常應拆開。
  • Delegated test work must return the Completion Envelope.

Completion

回傳 framework、commands run、TDD 時的 red/green evidence、files changed、remaining coverage risk，以及 skipped test rationale。

Post-Task Reflection (required)

Execute post-task-reflection-checkpoint.md before reporting completion.
