Primary fit
UI testing validates that the interface works correctly before shipping a Windows desktop application — this is a pre-release quality gate, not a build activity. This skill directly implements automated UI testing via the winapp ui command, guiding scripted batch PowerShell tests and interactive exploration for WinUI 3 controls.
