Sdk: Unable to test non-Core code on Linux

Created on 17 May 2016  路  32Comments  路  Source: dotnet/sdk

(Apologies if this is the wrong repo for this; it's not clear to me whether this is xUnit-specific or the expected behaviour when testing on Linux.)

Background

I have projects which don't target core yet, but I still want to test on Travis. They work fine on RC1 (with dnx test and the old xUnit setup) and work fine with an updated project.json on Windows, but fail to run tests on Linux.

It's not clear whether the non-core runtimes/frameworks are expected to work on non-Windows platforms. Using dotnet run works fine for a console app with a TFM of net451, so it's clearly got _some_ knowledge... but dotnet test fails.

Similar issues: dotnet/sdk#4833, dotnet/sdk#5172.

Steps to reproduce

Create xUnit test project with a framework of net451, and run dotnet restore, dotnet build, dotnet test.

Sample project.json:

{
  "dependencies": {
    "xunit": "2.1.0",
    "dotnet-test-xunit": "1.0.0-rc2-build10015",
  },

  "testRunner": "xunit",

  "frameworks": {
    "net451": { }
  }
}

Sample C#:

using Xunit;

public class Test
{
    [Fact] public void Foo() {}
}

Expected behavior

Tests run (using Mono).

Actual behavior

Restore and build both work, but test fails:

dotnet-test Error: 0 : Microsoft.DotNet.Cli.Utils.CommandUnknownException: No executable found matching command "dotnet-test-xunit"  
  at Microsoft.DotNet.Cli.Utils.ProjectDependenciesCommandFactory.FindProjectDependencyCommands(String commandName, IEnumerable`1 commandArgs, String configuration, NuGetFramework framework, String outputPath, String buildBasePath, String projectDirectory)  
  at Microsoft.DotNet.Cli.Utils.ProjectDependenciesCommandFactory.Create(String commandName, IEnumerable`1 args, NuGetFramework framework, String configuration)  
  at Microsoft.DotNet.Tools.Test.ConsoleTestRunner.DoRunTests(ProjectContext projectContext, DotnetTestParams dotnetTestParams)  
  at Microsoft.DotNet.Tools.Test.TestCommand.DoRun(String[] args)

I has been some time since this issue was raised. Is the above nasty workaround the only real solution at this point? The alternative being to wait for a preview3 tooling release?

As far as I can tell, one issue is that there's no specific Mono RID, so there's no runtime exe that we can create in the dotnet-test-xunit package for this.

/cc @bradwilson @piotrpMSFT

Smells like a tooling problem, not an xUnit.net problem.

So I reported it in the right repo by chance? Result :)

Do let me know if there's anything I can do to help diagnose it. I realize there are a lot of variables in play here.

I'm getting this error ( No executable found matching command "dotnet-test-") as well but with dotnet core on osx. I'm not finding much via googlebing so adding onto this relatively similar thread ...because it puts me in such good company. :)

@julielerman can you share your project.json?

I've been mucking with it but results are still the same:

{
    "version": "2.0.0-*",
    "description": "",
    "authors": [
        ""
    ],
    "dependencies": {
        "Microsoft.EntityFrameworkCore.InMemory": "1.0.0-rc2-final",
        "src": "2.0.0",
        "xunit": "2.1.0",
        "dotnet-test-xunit": "1.0.0-rc2-build10015"
    },
    "frameworks": {
        "netcoreapp1.0": {
            "dependencies": {
                "Microsoft.NETCore.App": {
                    "type": "platform",
                    "version": "1.0.0-rc2-3002702"
                }
            },
            "imports": [
                "dnxcore50",
                "portable-net45+win8"
            ]
        }
    }
}

So to be clear, the above works on Windows but not OSX?

have not done any of this on windows. using vscode on a mac. Also, I have a full project that is running. I will create a 1+1=2 test and try to run that to be sure it's not a problem related to the dependency on that other project. Also, the only other ref I found to this error message was followed by "oh ..typo in project.json...sorry" but I can't see one and vscode is not reporting any issues. Thanks!

dotnet-test should be dotnet test, if you're still seeing that error. If you're not typing that yourself, then it seems like you need to update your tools/SDK.

You're missing the testRunner entry. This may help: http://xunit.github.io/docs/getting-started-dotnet-core.html

@bradwilson gah! I saw that but was so focused on the dependencies section. Running up to my macbook to try it out and will let you know.

got it. sorry for my little RTFM snafu, @bradwilson . Sorry @jskeet for piggy backing. You _do_ have that specification in your project.json.

I have the exact same problem as @jskeet in windows with TFM net452. Maybe it's not related to linux?

@alberto-riggi: Just to check - you're having this problem on Windows? It only bit me on Linux. (My tiny sample works on Windows with both net451 and net452.)

@jskeet , correct, on windows.
I saw there is another issue regarding this https://github.com/dotnet/cli/issues/1370 .
Your example in win works just targeting net452?
I've read somewhere that if you have net45x and aspnet core as TFMs it works.

@alberto-riggi Yes, it works with just net452 - see the code/config in my first post, but with net452. It might be worth you trying that too.

Thanks john, I had to use "dotnet-test-xunit": "1.0.0-rc3-build10019" though.
As pointed here
https://github.com/dotnet/cli/issues/1370#issuecomment-220723436

Got it works with work around on Ubuntu 14.04
Project:

I confirm that dotnet test does NOT work on linux when targetting net451.

Setup:

  • Debian 8 (x64)
  • Mono 4.2.3
  • Dotnet 1.0.0-preview1-002702

project.json:

    "dotnet-test-xunit": "1.0.0-rc3-build10019"
  },

  "frameworks": {
    "net451": { }
  }
}

Output of dotnet test:

sebok$ dotnet test

However, the build created directory bin/Debug/net451/debian.8-x64, from which I can manually run dotnet-test-xunit.exe:

Same behaviour as @sebok - dotnet test works on windows but no osx.10.11 using net451

  • osx.10.11
  • Mono 4.2.3
  • dotnet 1.0.0-preview1-002702

            ]
        },
        "net451": {}
    }
}

Running dotnet test fails with the following output:

If a net451 exe exists in the package, you will have to do a mono bootstrap script.

#!/usr/bin/env bash

SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
  DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
  SOURCE="$(readlink "$SOURCE")"
  [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"

exec mono "$DIR/dotnet-test-xunit.exe" "$@"

@onovotny @julielerman @andrewlock The script above may help you.

So just putting the script where the exe is will not help. I will have to fork the repo and add a makefile to install this on *nix machines.

@borgdylan Thanks for your script. I'm using, with the following improvements:

  • Including your script at my test projects root directory
  • Putting the following configuration on projector.json:

"buildOptions": { "copyToOutput": "dotnet-test-xunit" }

  • Adding the following line to .gitattributes:

dotnet-test-xunit -text

This way, your script always gets copied to output directory, and I'm able to run test as I would normally would: dotnet test

This is a more elegant solution than the one I used.

We were stumbling over the same problem recently. I'm referencing dotnet-text-xunit version 2.2.0-preview3-build1047 in a net461 project; on Ubuntu 14.04 LTS dotnet test fails with

No executable found matching command "dotnet-test-xunit"

However, when I copy ~/.nuget/packages/dotnet-test-xunit/.../runtimes/unix-x64/lib/net451/dotnet-test-xunit.exe to the output directory of the test project (e.g. runtimes/unix-x64/lib/net451/dotnet-test-xunit.exe) and then add @borgdylan's script to the _same_ directory, dotnet test works.
That's an awful lot of work, however.

project.json looks like:

{
  "buildOptions": {
    "debugType": "portable",
    "preserveCompilationContext": true
  },

  "dependencies": {
    "dotnet-test-xunit": "2.2.0-preview3-build1047",
    "xunit": "2.2.0-beta3-build3401",
    "FluentAssertions": "4.14.0",
    "MyProject": { "target": "project" }
  },

  "testRunner": "xunit",

  "frameworks": {
    "net461": { }
  }
}

I has been some time since this issue was raised. Is the above nasty workaround the only real solution at this point? The alternative being to wait for a preview3 tooling release?

The bash script workaround no longer works when upgrading to the latest .NET SDK 1.0.1. The tests do run when using mono xunit.console.exe test.dll, but dotnet test fails to find any "again", specifying "'TestAdapterPath' does not contain any test adapters", continues with "permission denied", then exits.

@bravecobra - I have the exact same problem. Do you know of any workaround?

@AdamPD if you can upgrade your xunit project up to 2.3.0-beta3 you can use the dotnet-xunit tool which I added support for mono https://www.nuget.org/packages/dotnet-xunit/ https://github.com/xunit/xunit/pull/1213

dotnet xunit is removed starting from xunit 2.4 Ref: Release Notes 2.4
Excerpt from the Release Notes:

Unfortunately, this release also removes the dotnet xunit runner, as the stability of the runner was never perfect, and it suffered from many assembly-loading related issues. Users from .NET Core can continue to use VSTest (either inside Visual Studio, or via dotnet test).

So, for xunit framework test use the command

dotnet test
