Vitest Runner Optimized

A lightweight VS Code extension for running Vitest tests directly from your editor. Execute, debug, or stress-test individual test cases with a single command.

Why This Extension?

• Zero configuration — works out of the box with any Vitest project
• Real terminals — each test runs in its own integrated terminal, no output collision
• Flaky test detection — loop a test N times to catch intermittent failures
• Minimal footprint — does one thing well without bloat

Commands

Access these via Command Palette (Cmd+Shift+P / Ctrl+Shift+P) while your cursor is inside a test block.

Configuration

{
  // Number of iterations for Run ×N (default: 20)
  "vitestRunner.loopCount": 20,

  // Additional arguments passed to Vitest
  "vitestRunner.extraArgs": ["--pool=threads"],

  // Enable FORCE_COLOR=1 environment variable (default: true)
  "vitestRunner.forceColorEnv": true,

  // Append --color flag to Vitest (default: true)
  "vitestRunner.addColorFlag": true
}

Supported Platforms
