vitest-testing

What it does

This skill enables AI agents to execute Vitest tests directly within their environment, allowing for automated verification of code changes. It streamlines the testing workflow by integrating the popular Vitest runner into the agent's operational capabilities.

When to use it

• Validate logic updates in JavaScript or TypeScript applications before merging pull requests.
• Run regression suites to ensure new features do not break existing functionality.
• Generate test coverage reports to identify untested code paths during development sprints.
• Automate unit tests for microservices where rapid feedback on build integrity is critical.

Key capabilities

• Executes Vitest commands directly in the agent's runtime environment.
• Supports running specific test files or entire suites via command-line arguments.
• Captures and reports test results, including pass/fail statuses and error logs.
• Integrates seamlessly with projects already utilizing the Vitest ecosystem.

Example prompts

• "Run all tests in the src/utils directory using Vitest and summarize any failures."
• "Execute the specific test file auth.test.ts to verify the new login flow implementation."
• "Generate a coverage report for the current branch and highlight modules with less than 80% coverage."

Tips & gotchas

Ensure your project has Vitest installed as a dev dependency before invoking this skill, or the agent will fail to locate the binary. For large codebases, consider instructing the agent to run tests in parallel using the --run flag for faster execution times.
