unittests 在构建服务器上失败，无法加载类型 'Microsoft.VisualStudio.TestTools.UnitTesting.ClassCleanupBehavior

Question

我有一个程序集可以在我的 PC 上正常构建和单元测试，但无法在构建 PC 上进行测试。它已经失败了大约一个月。我很可能做错了什么。这是我从构建服务器得到的响应。

16:29:38     Project "xyz.Utilities.UnitTests.csproj": VSTest
16:29:40     Test run for C:\Bin\Release\net5.0-windows\xyz.Utilities.UnitTests.dll (.NETCoreApp,Version=v5.0)

16:29:40     
16:29:40     Starting test execution, please wait...
16:29:40     A total of 1 test files matched the specified pattern.
16:29:41     An exception occurred while invoking executor 'executor://mstestadapter/v2': Could not load type 'Microsoft.VisualStudio.TestTools.UnitTesting.ClassCleanupBehavior' from assembly 'Microsoft.VisualStudio.TestPlatform.TestFramework, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

我的项目文件很简单：

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <TargetFramework>net5.0-windows</TargetFramework>
        <IsPackable>false</IsPackable>
    </PropertyGroup>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
        <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
        <GenerateSerializationAssemblies>Off</GenerateSerializationAssemblies>
        <CheckForOverflowUnderflow>true</CheckForOverflowUnderflow>
        <OutputPath>$(SolutionDir)\Bin$(Configuration)</OutputPath>
    </PropertyGroup>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
        <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
        <GenerateSerializationAssemblies>Off</GenerateSerializationAssemblies>
        <CheckForOverflowUnderflow>true</CheckForOverflowUnderflow>
        <OutputPath>$(SolutionDir)\Bin$(Configuration)</OutputPath>
    </PropertyGroup>
    <ItemGroup>
        <PackageReference Include="EasyTcp" Version="4.0.0" />
        <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.11.0" />
        <PackageReference Include="MSTest.TestAdapter" Version="2.2.7" />
        <PackageReference Include="MSTest.TestFramework" Version="2.2.7" />
        <PackageReference Include="coverlet.collector" Version="3.1.0">
          <PrivateAssets>all</PrivateAssets>
          <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
        </PackageReference>
    </ItemGroup>
    <ItemGroup>
      <ProjectReference Include="..\xyz.Utilities\xyz.Utilities.csproj" />
    </ItemGroup>
</Project>

我认为这与构建服务器上的 Visual Studio 版本有关。我们是运行 Teamcity。有人知道吗？

Answer 1

将您的 nuget 包升级到最新版本，它应该可以解决您的问题。我认为 MSTest.TestAdapter 和 MSTest.TestFramework.

需要 2.2.8

Answer 2

我已经按照建议升级了，现在可以正常使用了。
