How does it handle code coverage?

It uses Istanbul/c8 to track coverage, enforcing a minimum threshold of 80% line coverage and 100% for critical business logic.

How does it assist with bug verification?

It follows a 4-step process: reproducing the bug with a failing test, implementing a minimal fix, verifying the pass, and adding a regression test.

Can it mock external APIs like Supabase?

Absolutely. It includes pre-defined mocking guidelines for Supabase clients and React Query to ensure tests remain isolated and fast.

Does it support Test-Driven Development (TDD)?

Yes, it includes a structured TDD workflow that guides you through writing failing tests (Red), passing code (Green), and refactoring.

Which testing frameworks does this skill support?

This skill is specifically optimized for Vitest and React Testing Library for unit tests, and Playwright for end-to-end browser automation.
