Does this skill work with specific testing frameworks?

Yes, it is project-agnostic and works with any testing framework, including Jest, Pytest, Mocha, or Vitest, by focusing on universal testing principles.

When should I invoke the TDD Feature Development skill?

You should invoke this skill at the very beginning of a feature request, before using any other development workflows, to ensure testing is integrated into the initial planning phase.

Why does the skill discourage testing private functions?

Testing private functions creates brittle tests that break during refactoring. This skill emphasizes testing the public API to ensure the code's behavior remains consistent regardless of internal changes.

What is the recommended test coverage target?

The skill encourages aiming for an 80% code coverage baseline, which ensures that all critical logic paths are exercised without the diminishing returns of trying to test trivial code.

Seguridad y Pruebas

Integrates test-driven development practices into feature implementation workflows to ensure high-quality code and comprehensive test coverage.

TDD Feature Development is a specialized Claude Code skill designed to prioritize software quality by mandating test-driven development (TDD) principles from the very start of the development cycle. It transforms how features are built by requiring tests to be planned as distinct, trackable tasks before implementation begins, ensuring that code is testable by design. By focusing on public API behaviors rather than internal implementation details, this skill helps developers achieve a target of 80% coverage while creating resilient, maintainable codebases that are easy to refactor.
