Can I test validation errors with these patterns?

Yes, it includes specific patterns for simulating Umbraco-style validation errors (400 Bad Request) to ensure your UI handles feedback correctly.

Does this require a live Umbraco instance?

No, the skill is designed to help you test in isolation by mocking all backend dependencies, allowing for faster and more reliable test suites.

What version of MSW does this skill support?

This skill is fully optimized for MSW v2, utilizing the latest http and HttpResponse syntax for network interception.

How do I handle state between different API calls?

The skill provides a 'Mock Database' pattern that allows your mock handlers to read, create, update, and delete data in a local memory store during tests.

Simplifies API mocking for Umbraco backoffice extensions using Mock Service Worker (MSW) v2 patterns.

Acerca de

This skill provides specialized patterns and configurations for testing Umbraco CMS backoffice extensions without requiring a live backend instance. By leveraging Mock Service Worker (MSW) v2, it enables developers to intercept network requests and return precise mock responses, making it ideal for testing complex error states, loading behaviors, and edge cases. It includes ready-to-use handlers for GET, POST, PUT, and DELETE operations, along with a mock database pattern for maintaining state across test cycles.
