tdd

To enforce test-first development, you write a failing test defining the contract, then implement minimal code to pass it. This Skill guides the RED-GREEN-REFACTOR cycle across TypeScript layers including DAL, API routes, and server actions.

The best way to structure TDD workflows is using guided paths for features, refactoring, and bugfixes. This approach uses explicit mock patterns and the AAA structure to improve test coverage and maintainability while driving disciplined, auditable development.

To write failing tests for Next.js server actions and hooks, you establish a contract-first mindset using explicit mock patterns. This Skill provides safety checks and a directory-structured manifest to drive consistent test coverage across these specific application layers.

Yes, this TDD workflow supports mock patterns for encryption and context layers. It enforces test-first development across these layers along with DAL, services, and components to ensure consistent quality and safety checks.

You can scale TDD practices in a large Next.js codebase by using a directory-structured manifest and guided workflows. This establishes contract-first testing conventions and tooling guidance to reduce defects and maintain auditable development.
