With the recent privacy concerns with Moq (see here, here and https://github.com/moq/moq/issues/1372), I think it would be wise to remove the dependency on Moq from the NuGet package.

I don't see why any consumers of the Microsoft.VisualStudio.Sdk.TestFramework NuGet package need to install the Moq package as well. The only place it seems to be used is in a single using declaration here:

The unit tests can continue to use Moq if you want, just as long as the published NuGet packages don't depend on it.

Starting with the 17.0 release (and fixed in the 17.2 release) we had a bug where installing this package would fail due to missing nuget dependencies.

See #4 (comment) for a workaround.

In a test project in VS, If I 'Run All' Tests from the class in VS, there are some random failing tests with the following message:

Message: 
    System.AggregateException : One or more errors occurred.
    ---- System.InvalidOperationException : Cannot create more than one System.Windows.Application instance in the same AppDomain.
    ---- The following constructor parameters did not have matching fixture data: GlobalServiceProvider gsp

Am I doing something wrong?

Hello 👋

I'm trying to install it via NuGet. Trying to install Microsoft.VisualStudio.Sdk.TestFramework. But getting this error

Error NU1101 Unable to find package Microsoft.Internal.VisualStudio.Interop. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, nuget.org

Also tried to check it on nuget.org but same issue

Maybe I'm doing something wrong? Could someone please help?

Best regards,
Alex

Is this an internal-only package? We work on a public project (microsoft/sarif-visualstudio-extension) and are interested in using this publicly. Thanks!

Does this support NUnit?
I have many unit test cases written in NUnit. Migration them seems difficult.

Would it be possible, please, if you've got a moment, now Visual Studio 2022 is out, to help us VSIX devs and release a built version of the head of the code to NuGet?

I seem to need it for testing a VS2022 VSIX that references v17 of the SDK. If there's a workaround let me know please. I have built my own version and it works, but I don't really want to publish that separately on NuGet.

I try to install this package . However, it always reports
`

Discovered this while unit testing a method that does something similar to:

IVsTask vsTask = this.JTF.RunAsyncAsVsTask(...., 
{
       cts.Token.ThrowIfCancellationRequested();
}

vsTask.GetResult(); // deadlocks

This is likely because MockVSTaskCompletionSource.SetCancelled method doesn't call TaskCompletionSource.SetCancelled.
