Does this skill support React projects?

Yes, it includes specific configurations and dependencies for React, as well as Vue and Svelte, ensuring the correct Testing Library packages are installed.

Can it help migrate from Jest to Vitest?

Yes, by configuring global APIs and setup files, it provides the necessary infrastructure to transition existing Jest tests to the Vitest environment with minimal friction.

Can I use this in a monorepo environment?

Absolutely. It detects and configures testing pipelines for Turborepo, Nx, pnpm, and npm/yarn workspaces, including workspace-specific filters.

Does it automatically set up code coverage?

Yes, it configures Vitest coverage using the v8 provider with pre-defined thresholds for lines, functions, and branches, and generates multiple report formats.

セキュリティとテスト

Configures Vitest as a comprehensive unit and integration testing framework with Testing Library integration and monorepo support.

This skill automates the setup of Vitest for modern JavaScript and TypeScript projects, ensuring a robust testing environment from the start. It handles core package installation, configuration of vitest.config.ts, TypeScript type integration, and the creation of global setup files for frameworks like React, Vue, and Svelte. Beyond basic setup, it intelligently manages monorepo architectures—including Turborepo, Nx, and pnpm—and enforces industry best practices like accessible query priorities and testing user behavior over implementation details.
