找不到SonarQube的Azure管道中的报告代码覆盖率

Question

我正在努力为SonarQube在Azure运营模式管道中生成代码覆盖率报告。我需要此代码覆盖率报告，以便SonarQube了解单元测试中覆盖的总代码。

我在获取单元测试期间创建的报告的步骤中收到此错误消息：

我在Azure Pipeline中生成报告所遵循的步骤：

1-在“dotnet构建”步骤之后，我包含了一个带有以下参数的“dotnettest”：

steps:
- task: DotNetCoreCLI@2
  displayName: 'dotnet test'
  inputs:
    command: test
    projects: '**/UnitTests.csproj'
    arguments: '--configuration $(buildConfiguration) /p:CollectCoverage=true /p:CoverletOutputFormat=opencover /p:CoverletOutput=./TestResults/'
  continueOnError: true

2-在“dotnet测试”之后，第一步包括一个PowerShell脚本来生成报告，并将该报告转换为适用于Azure DevOps的Cobertura格式:

steps:
- powershell: |
   dotnet tool install dotnet-reportgenerator-globaltool --tool-path .
   ./reportgenerator "-reports:$(Build.SourcesDirectory)/**/TestResults/coverage.opencover.xml" "-targetdir:coverage/Cobertura" "-reporttypes:Cobertura;HTMLInline;HTMLChart"
  displayName: 'Generate Coverage Report'

据我所知，在此超级外壳步骤之后，我将不得不再包含2个步骤才能将报告发布到Azure和Sonarqube中。但是，看起来我有一些问题来查找在单元测试期间生成的报告。

对这个有什么想法吗？

谢谢。

Answer 1

如果没有生成coverage.opencover.xml文件，请仔细检查您的测试项目是否有对coverlet.msbuild和opencover的nuget引用。可能只有coverlet.msbuild是必需的。您应该能够在DevOps的日志中看到这一点，例如:

Calculating coverage result...
  Generating report 'D:\a\1\s\coverage\coverage.opencover.xml'

根据我的经验，OpenCover在SonarQube上的表现比Cobertura好。

Answer 2

如果您在测试项目中添加了coverletcoveragenuget包，那么您根本不需要使用opencovere中间步骤。以cobertura格式提供输出，可以由代码覆盖率yaml任务发布

请看这里https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-test#examples

和

这里https://docs . Microsoft . com/en-us/dot net/core/testing/unit-testing-code-coverage？tabs=linux

例：

以下步骤执行测试，并将测试结果和代码覆盖率发布到 Azure 开发运营。如果要将代码覆盖率结果发布到 SonarQube 服务器，请使用文件 ./测试结果/**/覆盖率报告/Cobertura.xml并使用 PowerShll/脚本任务进行发布。

steps:
- task: DotNetCoreCLI@2
  displayName: 'dotnet test'
  inputs:
    command: test
    projects: '**/UnitTests.csproj'
    arguments: '--configuration $(buildConfiguration) --collect:"XPlat Code Coverage" -r ./TestTesults --logger trx --logger "console;verbosity=detailed"'
  continueOnError: true
- task: PublishTestResults@2
  displayName: Publishing Test Results
  condition: always()
  inputs:
    testResultsFormat: "VSTest"
    testResultsFiles: "./TestResults/**/*.trx"
    testRunTitle: "Unittests"
    failTaskOnFailedTests: true
- task: PublishCodeCoverageResults@1
  displayName: Publish Code Coverage Results
  condition: always()
  inputs:
    codeCoverageTool: "Cobertura"
    summaryFileLocation: "./TestResults/**/coverage.cobertura.xml"
    pathToSources: [Your code location]
    reportDirectory: ./TestResults/**/coveragereport/coveragereport
   

希望这有所帮助
