tdd-workflow

To enforce a TDD workflow and achieve 80% test coverage in TypeScript, you write failing tests first, then implement functionality, and finally verify coverage using Jest or Vitest for unit and integration tests, plus Playwright for E2E tests.

The best way to structure tests for JavaScript applications is to follow a structured workflow from user journey definition through test generation, implementation, and refactoring, utilizing Jest or Vitest for unit and integration tests, and Playwright for E2E tests.

Yes, this TDD workflow works with both Jest and Vitest for unit and integration testing, providing tooling guidance and mocking strategies for JavaScript and TypeScript applications to achieve at least 80% overall coverage.

Yes, you can use Playwright for E2E testing when applying test-driven development to new features, ensuring comprehensive coverage alongside unit and integration tests to prevent bugs and regressions in your codebase.

You should apply a test-driven development workflow during refactoring, bug fixing, and new feature development to ensure reliable, well-tested software by writing failing tests first and verifying at least 80% combined coverage.

To generate test cases from a user journey definition in test-driven development, you describe the user journey and let the skill generate the corresponding test cases to begin implementation, ensuring tests precede code functionality.
