pytest-mocking-strategy

Mocking is essential for unit testing, but over-mocking creates brittle tests that fail on refactoring. This skill provides a comprehensive framework for deciding what to mock, how to mock it safely, and when to use real objects instead.

Use when deciding what to mock in tests with "create mock", "mock external service", "AsyncMock pattern", or "what should I mock".

Do NOT use for domain testing (never mock domain objects), pytest configuration (use pytest-configuration), or test factories (use pytest-test-data-factories). Quick Start

掌握 pytest 的模擬策略：何時使用 autospec=True 與手動模擬、非同步程式碼的 AsyncMock 模式、模擬建構器和工廠，以及永遠不應該模擬的內容。包括類型安全的模擬創建模式和模擬與真實物件的決策矩陣。 使用時機：使用模擬依賴項建立單元測試，決定是模擬或使用真實對象，設定測試隔離，使用外部服務邊界測試案例，或建置可重複使用的模擬工廠。 來源：dawiddutoit/custom-claude。
