WinForms tests open real windows that take focus from the user's work. Test-Hidden.ps1 runs them on a separate Win32 desktop in the same window station, so forms keep real handles and message loops while nothing appears. A job object ends the whole tree on any exit, and a timeout stops runs stuck on a modal dialog nobody can dismiss there. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

.SYNOPSIS
|
|
Runs dotnet test on a hidden Win32 desktop so test windows cannot appear
|
|
on, or take focus from, the interactive desktop.
|
|
|
|
.DESCRIPTION
|
|
Every argument except -HiddenTimeoutMinutes goes to dotnet test unchanged.
|
|
With none, runs OpenNest.WinForms.Tests. Output streams back here and the
|
|
script exits with the dotnet test exit code, or 124 after a timeout.
|
|
See docs/hidden-desktop-tests.md.

|
|
# No param block: it would bind the first dotnet argument by position, and
|
|
# dotnet's short switches (-v, -e) by prefix. Everything is read from $args.
