Can it handle external API dependencies?

Yes, it includes specific mocking patterns for external services like Supabase, Redis, and OpenAI to ensure tests remain fast, isolated, and deterministic.

Does this skill work with existing codebases?

Yes, it is designed to be activated during refactoring or bug fixing to ensure that new changes are fully covered by tests while maintaining the integrity of existing functionality.

Is E2E testing included in the workflow?

Absolutely. The skill includes Playwright patterns to test critical user flows and browser-based interactions, ensuring full-stack reliability.

Which testing frameworks are supported?

The skill provides specialized implementation patterns for Jest, Vitest, and Playwright, though the core TDD principles can be adapted to most modern testing stacks.

How does it enforce the 80% coverage rule?

The workflow includes explicit steps to run coverage reports and verify that branches, functions, and lines meet the defined 80% threshold before a task is marked as complete.

セキュリティとテスト

Enforces a rigorous test-driven development cycle to ensure high-quality code with 80%+ coverage across unit, integration, and E2E tests.

The Test-Driven Development (TDD) Workflow skill transforms Claude into a disciplined software engineer that prioritizes reliability and maintainability by mandating a 'tests-before-code' approach. It guides the entire development lifecycle—from user journey mapping and test case generation to implementation and refactoring—while providing standardized patterns for Jest, Vitest, and Playwright. This skill is essential for developers building mission-critical applications who require strict 80% coverage thresholds and robust mocking strategies for services like Supabase, Redis, and OpenAI, ensuring every feature is production-ready and regression-proof.
