jenkins - jenkins 中的 VStest 代码覆盖率报告

Question

我正在使用 Jenkins 为 .Net 项目设置 CI。

我使用 MSTest 插件和 VStestrunner 插件来运行测试。现在我有 .trx 文件和 .Coverage 文件我在显示代码覆盖率报告时遇到问题

如果你知道任何插件可以做到这一点，请帮助我。

Answer 1

我为此苦苦挣扎了很久，终于发现我们可以使用“CodeCoverage.exe”“ReportGenarator.exe”和“Cobertura plugin”来显示完美的覆盖率报告。

“ReportGenerator.exe”可以从https://github.com/danielpalme/ReportGenerator/releases获得

• 首先使用“CodeCoverage.exe”将 .coverage 文件转换为 .xml 文件

    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Team Tools\Dynamic Code Coverage Tools\CodeCoverage.exe" analyze -output:./TestResults/coverage.xml ./TestResults/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.coverage"

• 第二次使用 ReportGenerator.exe 将 vstest xml 格式转换为 Cobertura xml 格式

    "ReportGenerator_4.4.7\net47\ReportGenerator.exe" -reports:./TestResults/coverage.xml -targetdir:./TestResults -reporttypes:cobertura

• 最后安装cobertura插件用它来收集xml文件，这里给出一个管道使用示例

    post {
        always {
            cobertura coberturaReportFile: './TestResults/Cobertura.xml'
        }
    }

• 结果就像这样

要显示覆盖率报告，您需要将其转换为 XML 格式并使用 MSTest 插件发布报告。MSTest 插件建议 ( https://wiki.jenkins-ci.org/display/JENKINS/MSTest+Plugin ) 使用第三方应用程序转换为 XML 格式和 powershell (您需要为其安装 pugin) 来运行它。

但是，您只能使用 PowerShell 对其进行转换。有脚本示例：

$coverageFile = $(get-ChildItem -Path .\TestResults -Recurse -Include *coverage)[0]
$xmlCoverageFile = ".\TestResults\vstest.coveragexml"

Add-Type -path "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Coverage.Analysis.dll"

[string[]] $executablePaths = @($coverageFile)
[string[]] $symbolPaths = @()

$info = [Microsoft.VisualStudio.Coverage.Analysis.CoverageInfo]::CreateFromFile($coverageFile, $executablePaths, $symbolPaths);
$data = $info.BuildDataSet()

$data.WriteXml($xmlCoverageFile)

您可能需要Microsoft.VisualStudio.Coverage.Analysis.dll根据您的 VS 版本修复路径。

执行此操作的完整脚本是：

<#
.SYNOPSIS
    Script to convert code coverage report into xml format that can then be published by external tools.

.DESCRIPTION
    Covering code coverage statistics as part of quality improvement initiatives.    
#>
Param(
    [String] $InputCoveragePath =@("..\GeneratedFiles\Docs\Reports"),
    [String] $OutputCoverageFileExtension =@(".coveragexml"),
    [String] $CoverageAnalysisAssembly =@("Microsoft.VisualStudio.Coverage.Analysis.dll"),
    [String[]] $ExecutablePaths =@(""),
    [String[]] $SymbolPaths =@("")
)
    $ScriptLocation = Split-Path $script:MyInvocation.MyCommand.Path -Parent
    Write-Host $ScriptLocation

$RunAs32Bit = {
    Param(
        [String] $InputCoveragePath =@("..\GeneratedFiles\Docs\Reports"),
        [String] $OutputCoverageFileExtension =@(".coveragexml"),
        [String] $CoverageAnalysisAssembly =@("Microsoft.VisualStudio.Coverage.Analysis.dll"),
        [String[]] $ExecutablePaths =@(""),
        [String[]] $SymbolPaths =@(""),
        [String] $ScriptLocation =@(".")
    )
    Write-Host "[CoverageConverter][Begin]: Coverage conversion started..."

    Write-Host "[CoverageConverter][InputCoveragePath]: $InputCoveragePath"
    Write-Host "[CoverageConverter][OutputCoverageFileExtension]: $OutputCoverageFileExtension"
    Write-Host "[CoverageConverter][CoverageAnalysisAssembly]: $CoverageAnalysisAssembly"
    Write-Host "[CoverageConverter][ExecutablePaths]: $ExecutablePaths"
    Write-Host "[CoverageConverter][SymbolPaths]: $SymbolPaths"
    Write-Host "[CoverageConverter][ScriptLocation]: $ScriptLocation"
    
    Add-Type -path "$CoverageAnalysisAssembly"

    $Result = 0
    if($InputCoveragePath -and (Test-Path "$InputCoveragePath") )
    {
        [string[]] $coverageFiles = $(Get-ChildItem -Path $InputCoveragePath -Recurse -Include *coverage)
        
        @($coverageFiles) | ForEach-Object {
            $coverageFile = $_
            $coverageFileOut = (Join-Path -Path $(Split-Path $_ -Parent) -ChildPath  ($(Get-Item $_).BaseName + "$OutputCoverageFileExtension"))

            Write-Host "If all OK the xml will be written to: $coverageFileOut"

            $info = [Microsoft.VisualStudio.Coverage.Analysis.CoverageInfo]::CreateFromFile($coverageFile, $ExecutablePaths, $SymbolPaths);
            if($info){
                $data = $info.BuildDataSet()
                $data.WriteXml($coverageFileOut)
            }
        }
    }
    else
    {
        Write-Host "Please specify a valid input coverage file."
        $Result = 1
    }

    Write-Host "[CoverageConverter][End]: Coverage conversion completed with result $Result"
    return $Result  
}

#Run the code in 32bit mode if PowerShell isn't already running in 32bit mode
If($env:PROCESSOR_ARCHITECTURE -ne "x86"){
    Write-Warning "Non-32bit architecture detected, processing original request in separate 32bit process."
    $Job = Start-Job $RunAs32Bit -RunAs32 -ArgumentList ($InputCoveragePath, $OutputCoverageFileExtension, $CoverageAnalysisAssembly, $ExecutablePaths, $SymbolPaths, $ScriptLocation)
    $Result = $Job | Wait-Job | Receive-Job
}Else{
    $Result = Invoke-Command -ScriptBlock $RunAs32Bit -ArgumentList ($InputCoveragePath, $OutputCoverageFileExtension, $CoverageAnalysisAssembly, $ExecutablePaths, $SymbolPaths, $ScriptLocation)
}

Answer 4

在 ghking 的回答之后，cobertura 抱怨虽然 xml 在磁盘上，但没有找到它。我必须从路径中删除“./”，以便 cobertura 能够找到该文件。

   post {
       always {
           cobertura coberturaReportFile: 'TestResults/Cobertura.xml'
       }
   }
