Vitest Test Runner Skill

Overview

This skill runs Vitest tests and parses results into actionable reports. It executes tests in non-interactive mode, extracts failure details (test name, assertion error, stack trace), and organizes results by test file with timing information. Use this skill when tests need to run and results need structured, complete reporting—not when tests need installation, creation, modification, or auto-fixing.

Instructions

Step 1: Verify Vitest Project

Before running tests, confirm Vitest is installed and configured. Why: Running tests in a non-Vitest project wastes time and produces misleading results. This skill is designed only for Vitest—not Jest, Mocha, or Playwright.
