How do I handle external API calls during integration tests?

The skill recommends and provides patterns for using MSW (Mock Service Worker) for frontend network mocking and VCR.py for backend recording/replaying of HTTP requests.

How does this skill help with database testing?

It provides patterns for setting up fresh in-memory SQLite instances or test containers with automatic teardown and transaction rollbacks to ensure clean state for every test.

Can I use this for frontend component testing?

Yes, it includes specialized patterns for React components using Testing Library and user-event to simulate real-world user interactions and service layer hooks.

Does it provide guidance on test coverage?

Yes, it defines specific coverage targets: 70%+ for API endpoints and component interactions, and 80%+ for the service layer.

Which frameworks are supported for API testing?

The skill includes specific implementation patterns for TypeScript (using Supertest) and Python (using FastAPI with Httpx/AsyncClient).

Implements production-ready integration testing patterns for APIs, databases, and UI components within Claude Code.

The Integration Testing skill provides Claude Code with a comprehensive framework for verifying how different parts of a software system work together. It includes ready-to-use patterns for testing API endpoints using Supertest and FastAPI, managing ephemeral test databases with SQLAlchemy, and validating React component interactions. By enforcing best practices like transaction rollbacks, in-memory database usage, and coverage targets, this skill ensures that complex service layer interactions and external API dependencies are tested reliably without manual boilerplate.
