Does it help with mocking external APIs?

Yes, it includes specific mocking patterns for common services such as Redis, Supabase, and OpenAI to ensure isolated testing.

How does it enforce the 80% coverage rule?

It provides specific workflow steps and configuration snippets to set global coverage thresholds within your project's test runner.

Is end-to-end (E2E) testing required by the workflow?

Yes, the skill integrates Playwright patterns to ensure that critical user flows are verified alongside unit logic.

What testing frameworks does this skill support?

The skill provides standardized patterns and configurations for Jest, Vitest (unit/integration), and Playwright (E2E).

Can I use this for bug fixing or only new features?

It is designed for both; the workflow encourages writing a failing test that reproduces the bug before implementing the fix.

Enforces rigorous test-driven development practices with comprehensive unit, integration, and E2E coverage requirements.

This skill automates and enforces a professional Test-Driven Development (TDD) cycle within Claude Code, ensuring that every feature, bug fix, or refactor is backed by robust testing. It mandates a 'tests-first' approach, setting an 80% coverage threshold across various testing layers including Jest/Vitest for unit logic and Playwright for end-to-end user journeys. By providing standardized patterns for mocking services like Supabase, Redis, and OpenAI, it helps developers build resilient, self-documenting codebases that are easy to maintain and refactor safely.
