To design tests for Clean Architecture, you must validate application boundaries, business logic, and infrastructure separately. This approach enforces layer boundaries so tests do not directly target internal classes, ensuring proper coverage.

A walking skeleton strategy in test design validates the end-to-end flow of a feature. It provides structural guidelines to ensure complete user journeys are tested across the entire architectural flow before deeper implementation.

Separating business and technical vocabulary in tests requires maintaining strict language abstraction. This ensures business rules are clearly distinguished from infrastructure concerns, keeping test scenarios aligned with domain logic.

You need to extract domain unit tests when existing test coverage is insufficient for core business logic. This extraction determines exactly when isolated domain tests are required to validate rules independently of infrastructure.

Yes, test mandates enforce layer boundary restrictions by applying four mandatory rules. These rules ensure tests do not directly target internal classes, maintaining strict separation between application boundaries and infrastructure.
