Running Windows GUI tests using Squish

I need to run Windows GUI test using Qt’s Squish tool in a CI/CD pipeline. This will require a “virtual display adapter” when running in a headless environment.

There is a virtual display adapter for Windows (see GitHub - VirtualDisplay/Virtual-Display-Driver: Add virtual monitors to your windows 10/11 device! Works with VR, OBS, Sunshine, and/or any desktop sharing software.) and I can install it locally but it will not install in CircleCI (no errors that I can find). My questions are:

  1. Why can’t I install the display adapter?
  2. Is there any other solution for running GUI tests in the Windows executor.

Regards,

Harry
