No tests discovered using xUnit on ASP.Net Core 1.0 project with build on Visual Studio Team Services Hosted agent

I have a problem where my xUnit tests in my ASP.Net Core 1.0 application are not discovered when building on Visual Studio Team Services.

The test project is being built successfully, but no test results are given. I find the following messages regarding the Visual Studio Test step in the log:

******************************************************************************

No results found to publish.

The tests are written like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using Xunit;

namespace project.tests
{
    public class ProjectTests
    {
        [Fact]
        public void PassingTest()
        {
            Assert.Equal(4, Add(2, 2));
        }

        [Fact]
        public void FailingTest()
        {
            Assert.Equal(5, Add(2, 2));
        }

        int Add(int x, int y)
        {
            return x + y;
        }
    }
}

The tests run just fine locally, but not on Visual Studio Team Services.

Someone posted this, i try this and it works http://blogs.perficient.com/microsoft/2016/08/unit-test-with-net-core-and-vsts/

  1. In Execution Options -> Test Assembly, put **\test**\project.json
  2. In Advance Execution Options -> Other Console Option, put /UseVsixExtensions:true /logger:trx

enter image description here

enter image description here

and the final result in visual studio team service enter image description here

The tests are not getting discovered since the xunit test adapter for vstest was not found. Here is what you can do

  1. add the xunit test adapter nuget reference to your test project
  2. add the restore nuget packages as the first step in your build definition

vstest should not be able to detect your xunit test adapter and then discover and execute the xunit tests

Enter "$(Build.SourcesDirectory)\SolutionFolderName\packages" in "Advanced Execution Options\Path to Custom Test Adapters" to set the test adapter to xUnit. Refer to this link for details: xUnit or NUnit with Visual Studio Online Build

Update: I just create a sample app to test this and get the same issue with you. However, if I copy the xunit assembly files into "dnx451" folder together with test.dll, the test will be completed successfully. enter image description here enter image description here

And since you are working on a Asp.Net Core project and has imported DNX runner, you can also add a "Command Line" task to use dnx test command to run the testing directly. enter image description here
