Testability Review
Detection
| ID | Pattern | Fix |
|---|---|---|
| TE1 | Direct import { db } usage |
Inject dependency as parameter |
| TE1 | new Service() inside class |
Constructor injection |
| TE2 | fetch() inside component |
Extract to hook/service, inject |
| TE2 | Mixed side effects + logic | Separate pure/impure |
| TE3 | Deep mock chains | Simplify dependencies |
| TE4 | Global config access |
Pass config as prop/parameter |
| TE4 | Date.now() in logic |
Inject clock/time provider |
| TE5 | Tight coupling | Depend on abstractions (DIP) |
Criteria
Test setup < 10 lines. No deep mock chains. Dependencies explicit.
