Can XUnit tests be run from within the project to be tested?

I'm wondering if it's possible to have xUnit tests in the same project as the source code is?
I added the xUnit reference, but when I execute the tests, Visual Studio tells me that the project has no tests. I also tried to use Microsoft.NET.Test.Sdk, but in that case an error was shown because the project had two entry points.

Project explorer showing included packages

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

Implementation and better naming of the test will follow later...

Solution

  • To get a console App with xUnit Test compiling is a little bit tricky. One way to acheive this is to tweak the console App csproj.

    Add the following statement in PropertyGroup section:

    <GenerateProgramFile>false</GenerateProgramFile>

    the final csproj should look like this:

    <Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net5.0</TargetFramework>
        <GenerateProgramFile>false</GenerateProgramFile>
    </PropertyGroup>

  <ItemGroup>
        <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.11.0" />
        <PackageReference Include="xunit" Version="2.4.1" />
        <PackageReference Include="xunit.runner.visualstudio" Version="2.4.3">
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
        </PackageReference>
  </ItemGroup>

</Project>
