| 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.
