我需要做什么才能让 TeamCity 针对我的项目正确生成覆盖率报告？
我有一个针对我的代码运行 DotCover 的自定义 powershell 构建脚本。构建脚本有一个像这样的覆盖方法
Function Invoke-NUnitWithCoverage ( [string] $targetAssembly, [string] $outputDir, [string] $runCommand){
$fileName = Get-TestFileName $outputDir $runCommand
$xmlFile = "$fileName-TestResults.xml"
$txtFile = "$fileName-TestResults.txt"
$coverageFile = "$fileName-CoverageResults.xml"
exec{ dotcover.exe analyse /TargetExecutable=$nunitRunnerDir\nunit-console.exe /TargetArguments="$targetAssembly /fixture:$runCommand /xml=$xmlFile /out=$txtFile /nologo /framework=4.0" /Output=$coverageFile /ReportType=xml } "Running code coverage '$runCommand' failed."
Write-Host "##teamcity[importData type='dotNetCoverage' tool='dotcover' path='$coverageFile']"
}
TeamCity 上的输出显示正确，但它没有生成报告。这是 TeamCity 日志。如您所见，存在生成失败。
