.net core 如何从dotnet test生成的VS coverage发布Cobertura coverage报告--collect"；代码覆盖率；？

因此，该过程可从以下步骤中推导并包含以下步骤：

运行覆盖率的测试，而不发布测试结果，因为我们需要控制生成的二进制覆盖率报告的位置（请参阅）

将VS二进制覆盖率结果转换为XML

安装报表生成器工具

使用reportgenerator工具将VS XML覆盖率转换为Cobertura

使用发布代码覆盖率Azure DevOps任务发布Cobertura报告

公布测试结果

可以使用以下YAML模板实现这些步骤：

parameters:
  BuildConfiguration: Debug

steps:
- task: DotNetCoreCLI@2
  name: Test
  displayName: Test
  inputs:
    command: 'test'
    publishTestResults: false
    arguments: '-c ${{ parameters.BuildConfiguration }} --no-build -l trx -r $(Common.TestResultsDirectory)\tests --collect "Code coverage"'

- task: PublishTestResults@2
  displayName: Publish Test Results
  inputs:
    testResultsFormat: VSTest
    testResultsFiles: '*.trx'
    searchFolder: $(Common.TestResultsDirectory)\tests
    testRunTitle: $(Build.DefinitionName)-$(Build.BuildNumber)
  condition: succeededOrFailed()

- powershell: |
    $cc = "$(Get-ToolFolderFromNuGet Microsoft.CodeCoverage)\..\build\netstandard1.0\CodeCoverage\CodeCoverage.exe"
    $BinaryCoverageFile = (Get-Item "$(Common.TestResultsDirectory)\tests\*\*.coverage").FullName
    & $cc analyze /output:$(Common.TestResultsDirectory)\vstest-coverage.xml $BinaryCoverageFile
  displayName: Convert Coverage Result To Xml

- task: DotNetCoreCLI@2
  inputs:
    command: custom
    custom: tool
    arguments: install --tool-path . dotnet-reportgenerator-globaltool
  displayName: Install ReportGenerator tool

- script: .\reportgenerator.exe -reports:$(Common.TestResultsDirectory)\vstest-coverage.xml -targetdir:$(Common.TestResultsDirectory)\coverage\report -reporttypes:"Cobertura"
  displayName: Create Cobertura Coverage Report

- task: PublishCodeCoverageResults@1
  displayName: Publish Coverage Results
  inputs:
    codeCoverageTool: 'Cobertura'
    summaryFileLocation: '$(Common.TestResultsDirectory)/coverage/report/Cobertura.xml'
    failIfCoverageEmpty: true

它使用my powershell函数

Get ToolFolderFromNuGet

从NuGet下载包，但除此之外，不使用自定义代码

无论如何，问题在于“发布测试结果”任务将二进制覆盖率结果作为超链接发布在覆盖率结果应该位于的同一选项卡中：

这是没有用的。如果我注释掉发布测试结果，覆盖率页面将显示预期结果：

但是现在我丢失了测试页面，当然：

有人知道如何解决这个难题吗

附言

我在这里打开了一个bug-

我试图在最后发布测试结果，甚至删除二进制覆盖率结果文件。没有任何帮助。

通过检查发布测试结果任务的diag日志，我设法找到了解决方法。事实上，从日志中可以看出：

因此，原始二进制覆盖率文件位于

我的错误是只删除了原始位置。当在这两个地方被删除时，代码覆盖率页面就如预期的那样——不再有无用的超链接，而是实际覆盖率

YAML中已更正的powershell任务如下所示：
