Does this skill support both Jest and Vitest?

Yes, it includes specialized configuration patterns and code examples for both the industry-standard Jest framework and the high-performance, Vite-native Vitest.

How does it handle external API dependencies during tests?

The skill provides several patterns for isolation, including global fetch mocking, module-level overrides with vi.mock, and architectural dependency injection.

Can I use this for frontend component testing?

Absolutely. It provides patterns compatible with Testing Library to help you validate React, Vue, or Svelte components and user interactions.

Is it suitable for Test-Driven Development (TDD)?

Yes, the skill is specifically designed to facilitate TDD and BDD by providing the necessary scaffolding to write failing tests before implementing features.

安全与测试

Implements robust testing strategies for JavaScript and TypeScript applications using modern frameworks like Jest and Vitest.

JavaScript Testing Patterns is a specialized Claude Code skill designed to streamline the creation of high-quality test suites. It provides comprehensive guidance for setting up testing infrastructure, writing maintainable unit and integration tests, and implementing advanced mocking strategies. By providing standardized patterns for Jest, Vitest, and Testing Library, it helps developers ensure code reliability across frontend and backend environments, supporting everything from pure function validation to complex asynchronous user flows and Test-Driven Development (TDD) workflows.
