Hello,
I am trying to set up testing within Visual Studio for ArcGIS Pro 2.9 running .Net framework 4.8. I am following the instructions here: https://github.com/Esri/arcgis-pro-sdk/wiki/ProGuide-Regression-Testing#part-1-create-unit-test-project
I have completed the steps up until creating the helper class, which seems to have a problem working with ArcGISTest:

I have used the references from the source code provided and checked that they do match to where everything is installed locally. All of the other references seem to work okay. The only one I have not been able to match to the documentation is ArcGISPro.dll which I am not able to find in the bin as the documentation suggests: "Make sure "ArcGISPro.dll" from the "bin" folder is also selected, this isn't referenced in the Add-In project."
I have checked all dlls in that folder and I'm not able to find that specific dll for the reference, and I am not able to find anything relating to testing.
Any ideas on how to move past this issue?
