tdd-workflow-typescript

This Skill enforces Test-Driven Development for TypeScript by guiding you to write tests before implementation, create minimal code to pass them, refactor safely, and verify 80%+ code coverage across unit, integration, and E2E tests.

The best way to achieve 80%+ code coverage is by following a strict TDD workflow. This Skill enforces comprehensive test coverage across unit, integration, and end-to-end tests utilizing Jest/Vitest, React Testing Library, and Playwright.

Yes, you can use Jest and Playwright together. This Skill leverages Jest/Vitest for unit and integration tests, React Testing Library for component tests, and Playwright for end-to-end tests to ensure robust TypeScript refactoring.

To start writing tests before code for a new TypeScript API endpoint, this Skill guides you to first define tests for expected behavior, error handling, and edge cases, then implement the minimal code required to pass those tests.

Yes, this TDD workflow supports React Testing Library. It is explicitly integrated alongside Jest/Vitest and Playwright to guide you through testing React components and verifying their behavior before writing the actual implementation code.
