使用 xunit 在 webapi 应用程序上运行 dotnet 测试

Question

我正在尝试根据本指南使用最新版本使用 xunit 设置 dotnet core webapi 项目：

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-with-dotnet-test （对了，我已经下载了github示例项目，也有同样的错误）

我的项目结构非常基础：

解决方案包含

• “PrimeService”项目（API）
• “PrimeService.Test”项目（xunit 测试）

运行“dotnet test”时出现以下错误：

这是 sln 的顶部：

Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 15
VisualStudioVersion = 15.0.26124.0
MinimumVisualStudioVersion = 15.0.26124.0
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "PrimeService", "PrimeService\PrimeService.csproj", "{AE9EB41F-3946-4577-AC13-EF9B7117BCD5}"
EndProject
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "PrimeService.Tests", "PrimeService.Tests\PrimeService.Tests.csproj", "{4EC37F9F-B5F3-4820-8476-689CE8BC1D2F}"
EndProject

这里是测试csproj

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

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.7.0" />
    <PackageReference Include="xunit" Version="2.3.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\PrimeService\PrimeService.csproj" />
  </ItemGroup>

</Project>

这里是 webapi csproj：

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

  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
  </PropertyGroup>

</Project>

有什么线索吗？

谢谢:-)

原来我在解决方案文件夹中运行“dotnet test”。

xunit 试图对 api 项目运行测试

在测试文件夹中运行“dotnet test”时一切正常
