Windows and Git Bash Testing Compatibility Guide

Overview

This guide provides essential knowledge for running Vitest, Playwright, and MSW tests on Windows, particularly in Git Bash/MINGW environments. It addresses common path conversion issues, shell detection, and cross-platform test execution patterns.

Shell Detection in Test Environments

Detecting Git Bash/MINGW

When running tests in Git Bash or MINGW environments, use these detection methods:

Method 1: Environment Variable (Most Reliable)

// Detect Git Bash/MINGW in Node.js test setup
function isGitBash() {
  return !!(process.env.MSYSTEM); // MINGW64, MINGW32, MSYS
}
