Prevents production-code-first development by enforcing a failing test (RED) before any implementation, tailored to Angular, NestJS, and Next.js testing patterns.
Use case example: Implement a new service method in the correct behavior and verify it using the appropriate unit test scaffold; only after RED is achieved, add the minimal method logic, then refactor setup and rerun to confirm GREEN stays.
Invoke sdcorejs-tdd before implementing a service/component/function/handler in your write-code task to generate a failing test first, then follow red-green-refactor to reach passing tests.

You enforce test-driven development by generating a failing test before implementation, using Angular TestBed or NestJS Jest patterns to verify the RED state fails for the right reason, then writing minimal code to reach GREEN before refactoring.
Writing a failing unit test requires generating framework-aware boilerplate first, ensuring the test fails specifically because the implementation is missing rather than broken setup, establishing a true RED state for the red-green-refactor cycle.
Yes, Angular TestBed is supported for unit-testing components by providing the correct boilerplate setup, ensuring tests fail for the right reason during the RED phase before adding minimal implementation logic to pass.
Minimal implementation code is guided by writing the least logic required to make the failing Jest test pass, satisfying the GREEN phase of red-green-refactor while keeping behavior stable for subsequent safe refactoring.
Yes, the TDD approach works with Next.js Jest testing patterns by providing specific boilerplate for handlers and functions, applying the same red-green-refactor verification rules across Angular, NestJS, and Next.js environments.
Tests fail for the wrong reason when setup is broken instead of the implementation being missing, so RED state correctness ensures your unit tests fail specifically due to missing production code before you proceed to the GREEN phase.
