Look for DLLs in RID directory, not just EXEs

[mwhelan]

My xproj test project targets netcoreapp1.0 and net46 (project.json defines them in that order). I have some tests that use a dependency that is only net46 so I am using #if directives to make it compile:

    public class SemanticVersioningTests
    {
#if NET46
        [Test]
        public void specify_has_no_public_api_changes()
        {
            var publicApi = PublicApiGenerator.PublicApiGenerator.GetPublicApi(typeof(IScenario).Assembly);
            publicApi.ShouldMatchApproved();
        }

        [Test]
        public void specify_autofac_has_no_public_api_changes()
        {
            var publicApi = PublicApiGenerator.PublicApiGenerator.GetPublicApi(typeof(AutofacContainer).Assembly);
            publicApi.ShouldMatchApproved();
        }
#endif
    }

When I right click the file and choose Test with > .Net Framework, I get the following error:

System.IO.FileNotFoundException: Could not load file or assembly 'nunit.framework, Version=3.4.1.0, Culture=neutral, PublicKeyToken=2638cd05610744eb' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

That's strange! Is there a dotnet-test-nunit.exe but no nunit.framework.dll in your output directory?

[mwhelan]

My folder structure is Debug\net46\win7-x64. That folder contains both dotnet-test-nunit.exe and nunit.framework.dll.
Interestingly, Specify.Tests.dll (the project being tested) is in the net46 folder, while all the other dlls are in the win7-x64 folder.

[jcansdale]

Could you check that nunit.framework.dll is v3.4.1?

[mwhelan]

Yes, it is.

[jcansdale]

Can I see your project.json file?

[mwhelan]

Yes, it is here. You can run the Specify.Tests project. In particular it is the APIs\SemanticVersioningTests.cs. I don't know if the #if directives are somehow influential.

[jcansdale]

Got it, thanks!

It looks like I'm making the incorrect assumption that apps that target "netcoreapp1.0" must have an entry point / be EXE files when compiled for .NET. It appears they don't actually have to be a console application (this just happens to be the way they're set up in the .NET Core project templates).

Hopefully this is simply a question of how I search for the .NET Framework assembly. I need to find the one in bin\Debug\net46\win7-x64 not bin\Debug\net46.

[mwhelan]

Have to admit, I'm quite hazy on the difference between console projects and class library ones. For example, if I created a class library, and then realised it should be a console app, can I edit the xproj or something? (apart from adding a main method, etc.). I don't think there is an option in the VS tooling in project properties.

[jcansdale]

Could you give this build a try:
TestDriven.NET-4.0.3356_Extraterrestrial_Alpha.zip

[jcansdale]

Seems to be working. 😄

[mwhelan]

Yup, sure does. Love your work @jcansdale !
