Unit tests require Fake repositories that precisely mirror real implementations to ensure reliability. By reading the actual implementation first, you can craft isolated unit tests that accurately reflect production data interactions and track created data effectively.

E2E tests must enforce essential safety rules to prevent dangerous data deletions. This involves applying specific safety patterns that restrict destructive operations, track created test data, and ensure the testing environment remains stable and secure throughout execution.

Handling edge cases and exceptions in test design requires covering boundary conditions and documenting expected failure modes. You should structure tests to validate access control, track created data, and ensure exceptions are clearly defined to enforce safe and realistic test coverage.

You need fake repositories for isolated unit testing when verifying business logic without hitting real databases. They mirror real implementations to provide reliable, isolated testing environments, ensuring tests run safely while accurately reflecting actual data access patterns.

Yes, this approach guides proper test structure, fixtures, and test data management across both unit and integration layers. It enforces consistent safety patterns, access control validation, and realistic behavior mirroring for all test types.
