How does the skill verify that tests are passing?

It uses the Bash and Edit tools to run environment-specific test runners, such as 'mix test' for Elixir or 'yarn test' for JavaScript/TypeScript, to confirm results.

Can I use this skill for UI styling?

The skill recommends skipping TDD for UI styling tweaks, configuration changes, or documentation updates, focusing instead on functional logic and API changes.

What is the core cycle of the TDD skill?

It follows the Red-Green-Refactor cycle: first write a failing test (Red), then implement the minimum code required to pass (Green), and finally optimize the code (Refactor).

Why does the skill insist on writing the test before the code?

Writing the test first prevents 'false positives' where a test might pass regardless of the implementation, and it ensures that all code written is directly tied to a specific requirement.

Which programming languages are supported?

The skill provides patterns for various stacks, including Elixir for backend development and TypeScript for frontend development, but the principles can be applied to any language.

Seguridad y Pruebas

Implements a disciplined Red-Green-Refactor cycle to ensure code reliability and high-quality software architecture.

The Test-Driven Development skill guides Claude to follow the rigorous TDD methodology by writing failing tests before any implementation code is added. By enforcing the Red-Green-Refactor cycle, it ensures that every new function, feature, or bug fix is verified by a test first, promoting cleaner code, fewer regressions, and better design patterns across both backend and frontend environments. This skill is ideal for developers who prioritize ethical, professional, and maintainable software development.
