+## テスト
+
+このプロジェクトでは、Promptfooを使用してAIコマンドの品質と安全性をテストしています。
+
+### テストのセットアップ
+
+```bash
+cd tests/promptfoo
+npm install
+```
+
+### テストの実行
+
+```bash
+# すべてのテストを実行
+npm test
+
+# 特定のテストスイートを実行
+npm run test:guardrails  # 記事のガードレールをテスト
+npm run test:commands    # コマンドの機能をテスト
+
+# テストレポートを生成
+npm run test:report
+```
+
+### CI/CD
+
+テストは以下のタイミングで自動的に実行されます：
+- mainブランチへのプッシュ時
+- プルリクエスト作成時
+- 手動でのワークフロー実行時
+
+詳細なドキュメント：
+- [セットアップガイド](tests/promptfoo/docs/setup-guide.md)

+# Claude Code + promptfoo + モック環境 連携テストシステム
+
+**article_guardrail_review.mdコマンド**の統合テストシステムです。
+
+## 🎯 テスト連携の仕組み
+
+```
+promptfoo → Claude Code Provider → `claude -p` → article_guardrail_review.md → モック記事
+```
+
+### 連携の特徴
+
+1. **Claude Code実行**: `claude -p .claude/commands/article_guardrail_review.md`でローカル実行
+2. **promptfoo評価**: カスタムエバリュエーターで精度測定
+3. **モック環境**: テスト用記事でガードレール違反検出テスト
+
+## 📁 構成
+
+```
+tests/promptfoo/
+├── providers/claude-code-provider.ts     # Claude Code (`claude -p`) 実行プロバイダー
+├── evaluators/                          # promptfoo カスタム評価関数
+├── mocks/articles/                      # ガードレール違反テスト用記事
+└── configs/                             # テスト設定
+```
+
+## 🚀 実行方法
+
+### 前提条件
+- Claude Code CLI (`claude`) がインストール済み
+- プロジェクトルートに `.claude/commands/article_guardrail_review.md` が存在
+
+### テスト実行
+```bash
+cd tests/promptfoo
+
+# 基本機能テスト（APPROVED判定確認）
+npm test
+
+# ガードレール違反検出テスト
+npm run test:guardrails
+
+# エッジケース・エラーハンドリングテスト  
+npm run test:edge-cases
+```
+
+## 🔍 テスト内容
+
+### 基本テスト
+- 正常記事 → **APPROVED** 判定
+- 出力形式適合性チェック
+
+### ガードレール違反検出（9カテゴリ）
+- 機密情報、個人情報、セキュリティ脆弱性
+- 悪意コード、不適切コンテンツ、ヘイトスピーチ
+- 政治偏見、医療アドバイス、虚偽情報
+
+### エッジケース
+- 空ファイル、破損ファイル、特殊文字等
+
+## ⚙️ モック環境
+
+`mocks/articles/` 配下のテスト記事：
+- `weekly-ai-digest-20250721.md` - 正常記事
+- `violations/*.md` - 各種違反パターン記事  
+- `edge-cases/*.md` - エラーケース記事
+
+## 📊 評価システム
+
+- **承認判定精度**: APPROVED/BLOCKED判定の正確性
+- **違反検出精度**: precision/recall/F1スコア
+- **出力品質**: 説明の明確性・根拠性評価
+
+## 🎯 目標指標
+
+- テスト実行時間: 30秒以内
+- 判定成功率: 90%以上  
+- 違反検出精度: 80%以上

+# Test Configurations
+
+This directory contains test configuration files for various Claude Code commands.
+
+## Available Test Configurations
+
+### article-guardrail-review.yaml
+Tests for the `article_guardrail_review` command that validates weekly AI digest articles for content policy compliance.
+
+**Test Cases:**
+1. Clean article review (should pass)
+2. Article with multiple violations (should be blocked)
+3. Empty article handling
+4. Missing file handling
+5. Output format verification
+
+**Run with:**
+```bash
+npm run test:article-guardrail
+# or
+CLAUDE_CODE_TEST_MODE=true npx promptfoo eval --config configs/article-guardrail-review.yaml
+```
+
+## Test Environment
+
+All tests use mock data to ensure reproducibility:
+- Fixed date: 2025-07-21
+- Mock articles in `mocks/articles/`
+- Mock resources in `mocks/resources/2025-07-21/`
+
+## Adding New Tests
+
+To add tests for a new command:
+
+1. Create a new configuration file: `configs/[command-name].yaml`
+2. Add mock data if needed in `mocks/`
+3. Update the provider if special handling is required
+4. Add a npm script in `package.json`
+
+## Test Results
+
+Test results are saved to:
+- Individual test results: `test-results/[command-name]-results.json`
+- HTML report: Run `npx promptfoo view` after tests
