Test Repository
Important: We Test Implementations, Not Interfaces
Repository interfaces (I{Entity}Repository) define contracts but contain no logic to test. We test the implementations that fulfill these contracts.
When to Test
Test repository implementations after you have:
- Created the repository interface (
create-repositoryskill) - Implemented at least one concrete implementation
Which Skill to Use
| Implementation | Skill | Location |
|---|---|---|
| MockDB (in-memory) | test-mockdb-repository |
tests/repositories/{entity}.mockdb.repository.test.ts |
| MongoDB | test-mongodb-repository |
tests/repositories/{entity}.mongodb.repository.test.ts |
Testing Strategy
Each implementation should be tested to verify it correctly fulfills the interface contract:
- CRUD operations: create, findById, findAll, update, remove
- Query features: filtering, pagination, sorting, search
- Edge cases: not found returns null, delete non-existent returns false
- Implementation-specific: MongoDB indexes, MockDB in-memory behavior
