Can this skill help with mocking external APIs?

Yes, it includes specific patterns for mocking global fetch, using module mocks, and implementing dependency injection to isolate code from external API dependencies.

Is this skill suitable for frontend testing?

While it focuses on core logic patterns, it includes support for Testing Library, making it highly effective for testing React, Vue, and other component-based frontend frameworks.

Which testing frameworks are supported by this skill?

The skill provides comprehensive support and configuration patterns for both Jest and Vitest, the two most popular modern JavaScript testing frameworks.

How does this skill handle TypeScript?

All patterns and configurations are optimized for TypeScript, including type-safe mocks, interface-based dependency injection, and ts-jest/vitest-native TS support.
