尽管测试成功，但VSTS测试任务仍然失败

Question

即使在VsTest任务下通过了所有测试，我仍然遇到错误。

2019-04-04T10:22:14.3913769Z Unable to find d:\a\r1\a\xxx\e2e\bin\Release\netcoreapp2.1\testhost.dll. Please publish your test project and retry.

当我在本地尝试以下但没有错误时：

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe C:\xxx\src\xxx.EndToEnd.Integration.Tests\bin\Debug\netcoreapp2.1\xxx.EndToEnd.Integration.Tests.dll /logger:trx 2>error.txt

我也尝试过this解决方案，但是没有运气。

build.yaml

- task: CopyFiles@2
      displayName: "Copy Files to: $(Build.ArtifactStagingDirectory)"
      inputs: 
        contents: '$(Build.SourcesDirectory)/src/xxx.EndToEnd.Integration.Tests/**'
        targetFolder: $(Build.ArtifactStagingDirectory)

    - task: DotNetCoreCLI@2
      displayName: "dotnet e2e tests"
      inputs:
        command: publish
        publishWebProjects: false
        projects: '**/*.csproj'
        arguments: --output $(Build.ArtifactStagingDirectory)/src/xxx.EndToEnd.Integration.Tests
        zipAfterPublish: false

    - task: PublishBuildArtifacts@1
      displayName: "Publish End-to-End Tests"
      inputs: 
        artifactName: e2e
        PathtoPublish: '$(Build.ArtifactStagingDirectory)/src/xxx.EndToEnd.Integration.Tests'

我在下面的日志中注意到它们的路径有所不同（即发布管道-d:\a\r1\a\EstimationCore\e2e\xxx.EndToEnd.Integration.Tests和构建管道- d:\a\1\a\src\xxx.EndToEnd.Integration.Tests\bin\Release\netcoreapp2.1

Answer 1

任务返回：Test Run Aborted.因此，并非所有测试都已执行。这是可能的原因：

Unable to find d:\a\r1\a\xxx\e2e\bin\Release\netcoreapp2.1\testhost.dll. Please publish your test project and retry.

我很高兴这导致测试执行失败:)。

该错误提示您应该在运行测试之前发布测试项目，以确保将所有依赖项都复制到输出目录中。

您尚未共享其余的工作流程，但是我冒犯错误中提到的内容很有意义。

确保所有路径均正确，以便找到正确的文件。在构建中，您可以控制发布中的--output中的路径，每个人工制品都会根据人工制品名称下载到特定位置。这是为了确保具有多个伪像的发行版本不会意外覆盖彼此的文件。

Answer 2

在对build.yaml进行以下更改之后，测试成功运行。因此，您可以看到问题出在文件夹路径上

task: CopyFiles@2不必要

- task: DotNetCoreCLI@2
      displayName: "dotnet e2e tests"
      inputs:
        command: publish
        publishWebProjects: false
        projects: '**/**/*.EndToEnd.Integration.Tests.csproj'
        arguments: --output $(Build.ArtifactStagingDirectory)
        zipAfterPublish: false

    - task: PublishBuildArtifacts@1
      displayName: "Publish End-to-End Tests"
      inputs: 
        artifactName: e2e
        PathtoPublish: '$(Build.ArtifactStagingDirectory)'
