typescript-testing SKILL.md skillA

typescript-testing from shinpr/ai-coding-project-boilerplate is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add shinpr/ai-coding-project-boilerplate/typescript-testing@git:20261014.f06813c

Pins git:20261014.f06813c in mdr.lock. Pin the fingerprint instead.

リポジトリに即したTypeScriptテスト設計、振る舞いの証明、独立性、モック境界の基準を適用する。ユニットテストの作成・レビュー時に使用。.

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.

# TypeScript テストルール

## 前提条件の検出

フレームワークやコマンドを選択する前に、`package.json`、ロックファイル、テスト設定、既存テストのimportを確認する。Vitest固有のルールはVitestが設定されている場合にのみ適用する。それ以外は、以下の振る舞い、独立性、エビデンスに関するルールを維持しつつ、リポジトリで設定済みのTypeScriptテストハーネスを使用する。実行可能なハーネスを特定できない場合は、確認したパスと不足しているコマンドまたは設定を報告する。

## テストフレームワーク

- **Vitest**: リポジトリ設定または既存テストで選択されている場合に使用
- テストのインポート: `import { describe, it, expect, beforeEach, vi } from 'vitest'`
- モックの作成: `vi.mock()` を使用

## テストの基本方針

### 品質要件
- **リグレッション保護**: クリティカルパス、ビジネスロジック、リグレッションが問題になる振る舞いにテストを集中させる。未検証の振る舞いが実害のあるリグレッションリスクを生む場合にテストを追加する
- **独立性**: 各テストは他のテストに依存せず実行可能
- **再現性**: 時刻、乱数、環境値、外部I/Oを制御し、同一の入力から同一の観測可能な結果を得る
- **可読性**: 各テストは1つの振る舞いを名前で示し、setup・action・assertionを分け、その振る舞いで使用する値だけをfixtureに含める

### テストの種類と範囲
1. **単体テスト(Unit Tests)**
   - 個々の関数やクラスの動作を検証
   - 外部依存はすべてモック化

2. **統合テスト(Integration Tests)**
   - 複数のコンポーネントの連携を検証
   - テスト対象の振る舞いを構成するin-processコンポーネントは実物を使用。外部I/Oはモック範囲の判断を参照
   - 主要な受け入れ基準を実装するフロー、またはin-processコンポーネントの境界をまたぐフローを検証

3. **機能横断検証**
   - 新機能が共有の統合ポイントに及び、その失敗が主要なユーザージャーニーまたは公開契約を壊す、あるいは副次的な観測可能な振る舞いを劣化させる場合は、既存機能の継続性を証明義務とする。その失敗を露出できる最も安い境界で証明する
   - 検証パターン: 既存機能動作 → 新機能有効化 → 既存機能の継続性確認

How to install

The exact contents, by fingerprint
mdr add shinpr/ai-coding-project-boilerplate/typescript-testing@sha256:8ea776af80ce00fe

The line at the top of this page pins the label git:20261014.f06813c, 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.
