The Standard Testing

You enforce TDD and testing standards by authoring a failing foundation test first, implementing the minimum code to pass, and then extending tests for validations and exceptions following a prescribed order.

The standard structure for organizing tests uses a three-axis layout covering root, logic, validations, and exceptions, ensuring consistent file layout and verification rigor across foundation services and related components.

Exception handling tests should be structured to ensure localized exceptions preserve inner causes and data, respecting dependency boundaries while capturing observable behavior through thorough logging to prevent regressions.

Yes, you can apply these testing standards to foundation services, as the framework specifically enforces deterministic validation, logging, and exception-mapping requirements across service components and related testing practices.

The best way to start is to write a failing foundation test first, implement the minimum code required to pass it, and then extend your tests for validations and exceptions following the prescribed testing order.

Your test structure needs a specific order because enforcing testing order and naming conventions ensures observable behavior is captured consistently, preventing regressions and aligning with robust exception handling requirements.
