# macOS E2E Testing Infrastructure

**Completed**: 2026-01-28
**Branch**: `050-macos-e2e-tests`
**Priority**: P2

## Overview

Comprehensive end-to-end testing infrastructure for macOS that validates all doit toolkit commands work correctly on macOS 12+ (Monterey, Ventura, Sonoma). The test suite includes 112 automated tests across 20 test files covering macOS-specific filesystem features, BSD utility compatibility, bash/zsh shell validation, and CI/CD integration with GitHub Actions macOS runners.

This feature completes cross-platform testing coverage alongside the Windows E2E test suite (`049-e2e-windows-tests`), ensuring full platform parity (Windows + Linux + macOS) for the doit toolkit.
