Facilitates fast unit testing and mocking within Vite-powered projects using a Jest-compatible API.
This skill integrates Vitest's powerful testing capabilities into Claude Code, enabling developers to write, debug, and optimize test suites with high efficiency. It provides deep domain knowledge for configuring Vite-native testing environments, implementing complex mocks via the 'vi' utility, and managing comprehensive code coverage. Whether you are migrating from Jest, setting up type-level testing, or optimizing CI/CD workflows with concurrent execution, this skill ensures your testing architecture follows modern best practices for ESM and TypeScript applications.
