【问题描述】：

我目前正在 Azure DevOps 中设置 CI 管道。在这个管道中，我想运行解决方案中的所有测试。

但是，管道在测试步骤失败并出现以下错误：

A total of 81 test files matched the specified pattern.
##[error]An exception occurred while invoking executor 'executor://mstestadapter/v2': Could not load file or assembly 'Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

我发现它无法加载程序集Microsoft.VisualStudio.TestPlatform 很有趣，因为我没有在任何地方引用它。我的参考资料如下：

<PackageReference Include="MSTest.TestFramework" Version="2.2.5" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.10.0" />
<PackageReference Include="MSTest.TestAdapter" Version="2.2.5" />
<PackageReference Include="NSubstitute" Version="4.2.2" />
<PackageReference Include="coverlet.collector" Version="3.1.0">
  <PrivateAssets>all</PrivateAssets>
  <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>

测试任务是这样配置的：

steps:
- task: VSTest@2
  displayName: 'Test Assemblies'
  inputs:
    testAssemblyVer2: |
     **\$(BuildConfiguration)\*test*.dll
     **\$(BuildConfiguration)\**\*test*.dll
     !**\obj\**
    runTestsInIsolation: true
    codeCoverageEnabled: true
    platform: '$(BuildPlatform)'
    configuration: '$(BuildConfiguration)'

以下是管道概览：

【问题讨论】：

您是否在此构建之前恢复了您的 nuget 包？
@subhankars 是的，我现在添加了管道本身的概述。

标签： .net unit-testing testing azure-devops pipeline

【解决方案1】：

所以，经过一番挖掘，我让它工作了。

我更改了管道以使用 .Net Core Tasks 而不是 Visual Studio Builds。然后它就起作用了。

以下是新管道的测试部分的概述：

这是测试任务的 Yaml：

steps:
- task: DotNetCoreCLI@2
  displayName: Test
  inputs:
    command: test
    projects: '$(Parameters.TestProjects)'
    arguments: '--configuration $(BuildConfiguration)'

【讨论】：

您应该提到您正在测试一个 .net 核心应用程序。很高兴它对你有用。
是的，我只用标签 .Net 而不是 .Net Core 来标记它。我的错误
