| Route handler | Test app builder + session simulation + app.inject() | | Repository | Mock DB connection + counter-based execute | | Framework plugin | Real framework instance + selective dependency mocks | | Pure utility | No mocks — test inputs/outputs directly | | Service w/ DI | Mock injected deps via forwarding pattern |

If your test runner uses mockReset: true, most examples from the internet will silently fail.

For complex TDZ cases (multiple interdependent mocks), use the globalThis registry pattern.

使用正確的模擬模式將測試覆蓋率新增至現有程式碼。在未經測試的模組中新增測試、為錯誤編寫回歸測試或使用者要求測試特定檔案時使用。處理mockReset:true、vi.hoisted()、轉發模式和測試應用程式建構器實用程式。 來源：acedergren/agentic-tools。
