Vitest Testing

What it does

This skill enables AI agents to execute Vitest tests directly within their workflow, allowing for automated verification of code changes. It integrates testing capabilities into the agent's execution environment to ensure reliability before deployment.

When to use it

• Validate logic updates in a React or Vue application before merging pull requests.
• Run regression suites after modifying shared utility functions or API clients.
• Verify that new feature implementations do not break existing user flows.
• Automate quality checks during the development cycle for Node.js projects.

Key capabilities

• Executes Vitest test runners with full command-line support.
• Generates detailed test reports and coverage metrics.
• Supports mocking dependencies and managing test environments.
• Integrates seamlessly with standard JavaScript and TypeScript project structures.

Example prompts

• "Run all unit tests in the src/utils directory and report any failures."
• "Execute the test suite for the new authentication module and show me the coverage report."
• "Mock the external API service and run the integration tests to verify error handling."

Tips & gotchas

Ensure your project has Vitest installed and configured with a valid vitest.config.ts or vite.config.js before invoking this skill. Agents may require explicit instructions on which test patterns (e.g., *.test.ts) to target if the suite is large.
