# Test: set -g default-shell "cmd.exe" works correctly
# Verifies cmd.exe can be used as default-shell via config and runtime set-option.
#
# Tests:
# 1. Full path config (C:\Windows\System32\cmd.exe)
# 2. Bare "cmd.exe" config
# 3. new-window inherits cmd.exe
# 4. split-window inherits cmd.exe
# 5. Env vars (PSMUX_SESSION, TMUX) set in cmd panes
# 6. Runtime set-option changes default-shell to cmd.exe
# 7. Bare "cmd" runtime set
#
# Run: pwsh -NoProfile -ExecutionPolicy Bypass -File tests\test_default_shell_cmd.ps1
