cpp-testing SKILL.md skillA

cpp-testing from affaan-m/ecc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add affaan-m/ecc/cpp-testing@git:20260303.32e9c29

Pins git:20260303.32e9c29 in mdr.lock. Pin the fingerprint instead.

C++ テストの作成/更新/修正、GoogleTest/CTest の設定、失敗またはフレーキーなテストの診断、カバレッジ/サニタイザーの追加時にのみ使用します。.

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.

What the file says

# C++ Testing(エージェントスキル)

CMake/CTest を使用した GoogleTest/GoogleMock による最新の C++(C++17/20)向けのエージェント重視のテストワークフローです。

## 使用タイミング

- 新しい C++ テストの作成または既存のテストの修正
- C++ コンポーネントのユニット/統合テストカバレッジの設計
- テストカバレッジ、CI ゲーティング、リグレッション保護の追加
- 一貫した実行のための CMake/CTest ワークフローの設定
- テスト失敗またはフレーキーな動作の調査
- メモリ/レース診断のためのサニタイザーの有効化

### 使用すべきでない場合

- テスト変更を伴わない新しい製品機能の実装
- テストカバレッジや失敗に関連しない大規模なリファクタリング
- 検証するテストリグレッションのないパフォーマンスチューニング
- C++ 以外のプロジェクトまたはテスト以外のタスク

## コア概念

- **TDD ループ**: red → green → refactor(テスト優先、最小限の修正、その後クリーンアップ)
- **分離**: グローバル状態よりも依存性注入とフェイクを優先
- **テストレイアウト**: `tests/unit`、`tests/integration`、`tests/testdata`
- **モック vs フェイク**: 相互作用にはモック、ステートフルな動作にはフェイク
- **CTest ディスカバリー**: 安定したテストディスカバリーのために `gtest_discover_tests()` を使用
- **CI シグナル**: 最初にサブセットを実行し、次に `--output-on-failure` でフルスイートを実行

## TDD ワークフロー

RED → GREEN → REFACTOR ループに従います:

1. **RED**: 新しい動作をキャプチャする失敗するテストを書く
2. **GREEN**: 合格する最小限の変更を実装する
3. **REFACTOR**: テストがグリーンのままクリーンアップする

```cpp
// tests/add_test.cpp
#include <gtest/gtest.h>

int Add(int a, int b); // プロダクションコードによって提供されます。

TEST(AddTest, AddsTwoNumbers) { // RED
  EXPECT_EQ(Add(2, 3), 5);
}

// src/add.cpp
int Add(int a, int b) { // GREEN
  return a + b;
}

How to install

The exact contents, by fingerprint
mdr add affaan-m/ecc/cpp-testing@sha256:f5e90ea6aa21b25f

The line at the top of this page pins the label git:20260303.32e9c29, 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.
