XUnit code lens (run test, debug test) not appear in solution workspace

VScode version: 1.19 OS: Mac OS X Hight Sierra

XUnit code lens appears in the project like workspace (one project only - csproj on top level). XUnit code lens does not appear in the solution like workspace (sln on a top level, projects inside folders).

Steps to reproduce:

1. Create solution ‘dotnet new sln’
2. Create test folder ‘mkdir Test’, ‘cd ./Test’
3. Create test project ‘create classlib’
4. Put this to csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.5.0" />
    <PackageReference Include="xunit" Version="2.3.1" />
    <DotNetCliToolReference Include="dotnet-xunit" Version="2.3.1" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.1" />
  </ItemGroup>
</Project>

1. Open workspace on csproj level, open test class - code lens appears.
2. Open workspace on sln level, open test class - code lens doesn’t appear.

Glad to see that everything is working properly. Thanks for following up!

Hello @DustinCampbell . I mean that I forgot to add a step with adding a test project to the solution.

Everything is working fine!

I don’t know the reason what was wrong.

I’ve made small research and I tried to reproduce exact environment for not showing code leans descriptions for tests. I had two solution types in one directory. I can’t edit test description, so I’ve made new below:

1. Create new ConsoleApplication in regular .Net (I used 4.6.1) by Visual Studio 2017 in directory X.

2. Create solution dotnet new sln -n CodeLensTest

3. Create test folder mkdir Test, cd ./Test

4. Create test project dotnet new classlib

5. Add project to solution dotnet sln ../CodeLensTest.sln add ./test.csproj

6. Add this code to ./Test/Class1.cs

using System;
using Xunit;

namespace test
{
    public class Class1
    {
        [Fact]
        public void Test1()
        {
            
        }
    }
}

1. Put this to csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.5.0" />
    <PackageReference Include="xunit" Version="2.3.1" />
    <DotNetCliToolReference Include="dotnet-xunit" Version="2.3.1" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.1" />
  </ItemGroup>
</Project>

1. Build project cd .. dotnet build CodeLensTest.sln

2. In VSCode open workspace on .Test/test.csproj level, open test class - code lens appears.

3. In another window of VSCode open workspace on ./CodeLensTest.sln level, open test class - code lens doesn’t appear.

In step 10 VSCode shows code lens!

csproj level:

sln level:
