Vitest Testing

The vitest-testing skill enables AI agents to execute and manage test suites using Vitest, a fast unit testing framework designed for Vite. It allows agents to run tests directly within the development environment, providing immediate feedback on code changes without requiring a separate build step.

When to use it

• Validate new feature implementations before merging code into the main branch.
• Run regression tests after refactoring existing logic to ensure no functionality is broken.
• Execute test suites in CI/CD pipelines to automate quality assurance checks.
• Debug failing tests by running specific test files or individual test cases interactively.

Key capabilities

• Executes Vitest test commands directly via the agent interface.
• Supports running all tests, specific test files, or individual test names.
• Provides real-time output of test results, including pass/fail status and error logs.
• Integrates seamlessly with Vite-based project structures for rapid testing cycles.

Example prompts

• "Run the full Vitest test suite for the src/utils directory and report any failures."
• "Execute only the tests labeled 'auth' to verify the login flow implementation."
• "Re-run the failing test case named calculateTotalPrice after I updated the pricing logic."

Tips & gotchas

Ensure your project is initialized with Vite and has Vitest installed as a dev dependency before requesting the agent to run tests. The skill relies on the local project structure, so agents cannot execute tests in projects that do not have a valid vitest.config.js or equivalent configuration file present.
