tdd-workflow

To structure TDD Red-Green-Refactor cycles, you write a failing test for the domain model, implement the minimum code to pass it, and refactor while maintaining alignment with DDD architectural boundaries.

Align unit and integration testing with DDD layers by targeting tests specifically across domain, use-case, controller, and adapter boundaries to maintain structural integrity and enforce architectural patterns.

The best way to organize acceptance testing across domain boundaries is to map tests directly to DDD-aligned architecture patterns, verifying behavior at the use-case and adapter layers without coupling to internal domain logic.

Test-driven development works effectively with layered DDD architectures by enforcing that tests respect domain boundaries, allowing independent verification of use-case, controller, and adapter components throughout the development cycle.

Your unit testing strategy likely breaks down because tests are crossing domain boundaries, which this TDD workflow prevents by enforcing strict layer-specific test guidelines across domain, use-case, controller, and adapter layers.
