Unable to load DLL 'wpfgfx_cor3.dll' or one of its dependencies during unit test #1328

Ql1m4xx · 2023-03-14T13:47:08Z

Description:
currently we are migrating our Windows Application (WPF) from .NET Framework 4.8 to .NET 6.
We are using NUnit to test our user interface but we are getting the error that the 'wpfgfx_cor3.dll' could not be loaded

Stacktrace:

Error : Productnamespace.GUIFoundation.Test.ControlTests.ExtendedControl.ExtendedControlTests.BaseElementViewModelTest
System.DllNotFoundException : Unable to load DLL 'wpfgfx_cor3.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)

It's the same issue like #1319

The workaround to adjust the nunit-agent.runtimeconfig.json is not feasible for us because we dont want to adjust the "installed" file that comes with the NUnit.Console

Used Version: 3.16.2

Thanks for your help in advance

OsirisTerje · 2023-03-14T14:23:39Z

Does it work with 3.15.2 ?

Does it work with 3.15.2 ?

I got not the same problem with version 3.15.2

Ok, then I assume it doesn't work with using dotnet test either?

It would also be great if you could provide a very small repro for this.

spkl · 2023-03-14T18:13:15Z

Hi OsirisTerje, I have created a repository with a repro for this: https://github.com/spkl/nunit-console-1328-repro
The test shows and then closes a dialog from a WPF library. I have pasted the results from dotnet test and the two discussed NUnit Console versions as a readme.

I'm on the same dev team as Ql1m4xx. This is not a perfect repro for our scenario, as we are also using a third-party library (DevExpress), but the errors seem to be comparable for now. Thanks for looking into this.

OsirisTerje · 2023-03-14T21:29:46Z

@spkl @Ql1m4xx Thanks for the repro. I can confirm I do see the same. It works when using Visual Studio (2022) and it works using dotnet test, either on csproj or directly on the test dll.

I'll summarize the results that I see:

Visual Studio 2022, it works:

dotnet test , project level , it works

dotnet test nunit-console-1328-test.dll, in the bin folder, It works:

All of these use the adapter version 4.2.1 (which has the engine 3.15.2 built-in)

It fails with the nunit console (version 3.15.2, and @spkl show it fails with 3.16.2 too)

As @CharliePoole have pointed out earlier, the assembly loading with the adapter is done by the MS testhost, and not the engine, whereas the console will do the loading itself. So that's where it struggles:

Thanks again, we can use this to start working on it.

@CharliePoole Any suggestions? (and yes, I have read the other stuff on this, so let's start from that.)
@rprouse Rings any bells?

I might have one additional clue.

The Microsoft Test SDK generates an entrypoint into each test assembly. It can be seen from any reflector like ILspy or dotpeek.
The entrypoint is called from the runtime, which is selected using a runtime.config.json in version and experience/workload.

Hence the unit test is simply deriving from Microsoft.NET.SDK, the resulting runtime should be NetCoreApp, hence a simple console application.
As the assembly under test actively uses WPF and this is executed during the test, it must use the WindowsDesktop runtime.

Hence adding

<UseWPF>true</UseWPF>

to the csproj of the unit test will actually enforce the runtime to select the WindowsDesktop App, which provides the WPF runtime libraries.

This way, the test should run.

@spkl @Ql1m4xx Can you please give it a try?

spkl · 2023-03-15T07:03:57Z

@carstencodes nunit-console-1328-test.runtimeconfig.json already contains Microsoft.NETCore.App and Microsoft.WindowsDesktop.App. I've tried adding UseWPF, but it changes nothing.
If I remember correctly from other issues, NUnit Console does not evaluate the runtimeconfig.json of a test assembly.

carstencodes · 2023-03-15T08:03:19Z

@spkl Yeah, but it lead me on the right track.

I had to run

$ COREHOST_TRACE=1 dotnet test 2> dotnet-test.corehost_trace.txt
...
$ COREHOST_TRACE=1 dotnet nunit  nunit-console-1328-test/bin/Debug/net6.0-windows/nunit-console-1328-test.dll 2> dotnet-nunit.corehost_trace.txt

and diff the resulting files to actually find it.

The target runtime is not determined by the test assembly but in this case by the starting process.

I replaced

{
  "runtimeOptions": {
    "tfm": "net6.0",
    "rollForward": "Major",
    "framework": {
      "name": "Microsoft.NETCore.App",
      "version": "6.0.0"
    },
    "configProperties": {
      "System.Reflection.Metadata.MetadataUpdater.IsSupported": false
    }
  }
}

with

{
  "runtimeOptions": {
    "tfm": "net6.0",
    "rollForward": "Major",
    "frameworks": [
      {
        "name": "Microsoft.NETCore.App",
        "version": "6.0.0"
      },
      {
        "name": "Microsoft.WindowsDesktop.App",
        "version": "6.0.0"
      }
    ],
    "configProperties": {
      "System.Reflection.Metadata.MetadataUpdater.IsSupported": false
    }
  }
}

in the nunit-console's runtime config json file.

The result was:

Hence, in order to support additional frameworks like WPF-Test, XUnit-STA, FlaUI or XAMLTest, it might be a good idea to create a desktop-runtime runner for these cases.
(It cannot be added to the regular runtime as it might actually break linux/mac support).

This is great info @carstencodes ,thanks for the work you put into it

OsirisTerje · 2023-03-16T08:21:13Z

@carstencodes @spkl @Ql1m4xx May I just ask: What is the reason you need to use NUnit.Console and not just use dotnet test?

Ql1m4xx · 2023-03-16T10:07:48Z

@OsirisTerje We are using NUnit.Console since 10 or more years to execute more than 10k tests with it. We parse the result and display it and it worked very well in the last decade.
A switch to dotnet test for us is not a thing that we can do over night.
We would highly appreciate that NUnit.Console supports us and I think other users, too, with a solution that dont requires the change of installed files.

CharliePoole · 2025-02-01T08:00:37Z

I need to re-confirm this in the latest release.

@FleurLotus Can you provide a repro for this? The simpler the better. :-) I'd like to make sure you are having the same problem as others on this thread.

FleurLotus · 2025-02-12T10:10:46Z

@CharliePoole

Here is the simplest solution I could NunitConsoleSample.zip

In VS I have

with nunit3-console.exe (from NUnit.Console-3.19.2\bin\net8.0)

my command

SET NUNIT=.\NUnit.Console-3.19.2\bin\net8.0\nunit3-console.exe
SET NET=bin\Debug\net8.0

"%NUNIT%" ".\Common.WPF.UnitTests\%NET%-windows\Common.WPF.UnitTests.dll"

I do not put the compiled version or the nunit-console to reduce the size.

Hoping it will help you
