Does this skill support Test-Driven Development (TDD)?

Yes, it encourages the Red-Green-Refactor process, guiding you to write failing tests first before implementing minimal code to pass them.

Which testing frameworks does this skill utilize?

The skill primarily uses Vitest as the test runner, Supertest for HTTP endpoint testing, and fast-check for property-based testing.

How does the skill handle database integration tests?

It provides patterns for using real test databases or in-memory instances, including automated migrations, seeding, and transaction rollbacks to ensure test isolation.

What is the recommended code coverage for backend services?

This skill mandates a minimum of 70% overall coverage, with specific targets of 80% for business logic services and 70% for API controllers.
