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:

  1. Created the repository interface (create-repository skill)
  2. Implemented at least one concrete implementation

Which Skill to Use

ImplementationSkillLocation
MockDB (in-memory)test-mockdb-repositorytests/repositories/{entity}.mockdb.repository.test.ts
MongoDBtest-mongodb-repositorytests/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
