将代码覆盖率结果添加到 Azure Pipelines for .NET6 web API 和 docker

Question

我正在尝试将代码覆盖率结果添加到 .NET 6 Web API 的 Azure 管道中，它被包装到 docker 容器中。

我用这些： Nuget 添加：“coverlet.msbuild”

Docker 文件：

RUN dotnet test "WebAPIProject.DataAccessLayer.Tests.csproj" --logger "trx;LogFileName=WebAPIProject.DataAccessLayer.Tests.trx" /p:CollectCoverage=true /p:CoverletOutputFormat=json%2cCobertura /p:CoverletOutput=/src/WebAPIProject.DataAccessLayer.Tests/TestResults/Coverage/

我的流水线各自的行：

      - task: Docker@2
    displayName: Build image for testing
    inputs:
      containerRegistry: '$(dockerRegistryServiceConnection)'
      repository: '$(imageRepository)'
      command: 'build'
      Dockerfile: '**/Dockerfile'
      buildContext: '$(Build.Repository.LocalPath)'
      tags: '$(tag)'
  - task: CmdLine@2
    displayName: 'Copy test and Code coverage results files out of the image'
    inputs:
      script: |
        docker build -f ./WebAPIProject.Core/Dockerfile --target build -t $(imageRepository):$(tag) . 
        docker create -ti --name testcontainer $(imageRepository):$(tag) 
        docker cp testcontainer:/src/WebAPIProject.DataAccessLayer.Tests/TestResults/ $(Build.ArtifactStagingDirectory)/TestResults
        docker rm -fv testcontainer
  - task: PublishTestResults@2
    displayName: 'Publish test results'
    inputs:
      testResultsFormat: 'VSTest'
      testResultsFiles: '*.trx'
      searchFolder: '$(Build.ArtifactStagingDirectory)/TestResults'
  - task: PublishCodeCoverageResults@1
    displayName: 'Publish code coverage results'
    inputs:
      codeCoverageTool: 'Cobertura'
      summaryFileLocation: $(Build.ArtifactStagingDirectory)/TestResults/Coverage/coverage.cobertura.xml'
      pathToSources: '$(Build.ArtifactStagingDirectory)/TestResults/Coverage'

我得到的是运行管道：

Calculating coverage result...
Generating report '/src/WebAPIProject.DataAccessLayer.Tests/TestResults/Coverage/coverage.json'
Generating report 
'/src/WebAPIProject.DataAccessLayer.Tests/TestResults/Coverage/coverage.cobertura.xml'

但是代码覆盖率结果任务删除了这个：

##[warning]No code coverage results were found to publish.

与上述方法一样，测试非常有效，我希望 Coverage 也能正常工作，但事实并非如此。代码中的错误是什么？

Answer 1

找到答案了。首先，我在项目

中修改了Dockerfile的/p:CoverletOutput参数

RUN dotnet test "WebAPIProject.DataAccessLayer.Tests.csproj" --logger "trx;LogFileName=WebAPIProject.DataAccessLayer.Tests.trx" /p:CollectCoverage=true /p:CoverletOutputFormat=json%2cCobertura /p:CoverletOutput=/TestResults/Coverage/

需要在命令行中添加另一个 docker cp 以复制 Coverage 结果，因此 cmdline 任务现在如下所示：

- task: CmdLine@2
    displayName: 'Copy test and Code coverage results files out of the image'
    inputs:
      script: |
        docker build -f ./WebAPIProject.Core/Dockerfile --target build -t $(imageRepository):$(tag) . 
        docker create -ti --name testcontainer $(imageRepository):$(tag) 
        docker cp testcontainer:/src/WebAPIProject.DataAccessLayer.Tests/TestResults/ $(Build.ArtifactStagingDirectory)/TestResults
        docker cp testcontainer:/TestResults/Coverage/ $(Build.ArtifactStagingDirectory)/coverage
        docker rm -fv testcontainer

其中还涉及修改发布代码覆盖率结果任务，例如：

- task: PublishCodeCoverageResults@1
    displayName: 'Publish code coverage results'
    inputs:
      codeCoverageTool: 'Cobertura'
      summaryFileLocation: '$(Build.ArtifactStagingDirectory)/coverage/coverage.cobertura.xml'
      pathToSources: '$(Build.ArtifactStagingDirectory)/coverage/'

我的收获是，即使我设置了 Testresult 的文件夹来发布覆盖率结果，出于某种原因，docker 还没有将这些放入文件夹中。因此，通过上面的这个小解决方法，我终于可以同时复制测试和覆盖率结果。
