test-mockdb-repository

Unit test MockDB repositories with Vitest by running an in-memory test suite that validates CRUD behavior without external database dependencies. The suite uses deterministic fixtures and beforeEach resets to ensure consistent, isolated test results.

In-memory repository testing validates data access layer logic using mock setups instead of a real database. You need it when you want fast, deterministic unit tests for CRUD flows that do not rely on external database infrastructure.

Yes, you can test filtering and pagination logic in MockDB repositories. The test suite provides comprehensive coverage for findAll, findById, update, and remove operations, including edge cases across multiple users.

No, this Vitest testing approach does not require external database dependencies. It validates repository behavior entirely in-memory, allowing you to verify CRUD flows and edge cases without connecting to a real database.

Ensure deterministic test results for MockDB data access layers by using beforeEach resets and consistent fixtures. This testing pattern guarantees that each unit test starts with a known state for reliable CRUD verification.
