.net - Resharper 未运行 xUnit 测试

Question

我有一个带有 xUnit 的 .NET Core 项目。不过，我无法再使用 Resharper 运行任何测试。即使是非常简单的测试也是不确定的。例如。:

using Xunit;

public class MyTests
{
    [Fact]
    public void MySuperTest()
    {
        Assert.Equal(1, 1);
    }
}

输出日志显示异常:

我的 Nuget 进口是:

<ItemGroup>
  <PackageReference Include="Microsoft.Extensions.DependencyModel" Version="1.1.2" />
  <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" />
  <PackageReference Include="Microsoft.NETCore.Portable.Compatibility" Version="1.0.1" />
  <PackageReference Include="System.Runtime.InteropServices.WindowsRuntime" Version="4.3.0" />
  <PackageReference Include="System.ServiceModel.Http" Version="4.3.0" />
  <PackageReference Include="xunit" Version="2.2.0" />
  <PackageReference Include="xunit.runner.console" Version="2.2.0" />
</ItemGroup>

Answer 1

错误在于我选择了要导入的 Nuget 包。

代替:

<PackageReference Include="xunit.runner.console" Version="2.2.0" />

我应该有:

<PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />

在此之后，您可能需要重建或关闭并重新打开 Visual Studio。
