dotcover.exe中的NUnit访问被拒绝错误

Question

我正在为dotCover编写PowerShell脚本，以使用NUnit-console.exe生成覆盖率报告运行脚本后-

$testRunner="C:\Program Files (x86)\NUnit 2.6.2\bin\nunit-console.exe"
$testContainers="path/to/test1.dll","path/to/test2.dll"
$dotcover="D:\JetBrains.dotCover.CommandLineTools.2019.3.4\dotcover.exe"

foreach($test in $testContainers)
{
$testAssembly=Get-Item $test
$testName= $testAssembly.BaseName
&$dotcover cover /TargetExecutable=$testRunner /TargetArguments=$test /Output="D:\JetBrains.dotCover.CommandLineTools.2019.3.4\TestReport\$testName.dcvr"
}

$testReports=$testContainer|%{
$testAssembly=Get-Item $test
$name= $testAssembly.BaseName
return ("D:\JetBrains.dotCover.CommandLineTools.2019.3.4\TestReport\{0}.dcvr" -f $name)
}

$testReportArguments=[String]::Join(";",$testReports)
&$dotcover merge /Source="$testReportArguments" /Output="D:\JetBrains.dotCover.CommandLineTools.2019.3.4\TestReport\mergedReport.dcvr" /ReportType="DCVR"


&$dotcover report /Source="D:\JetBrains.dotCover.CommandLineTools.2019.3.4\TestReport\mergedReport.dcvr" /Output="D:\JetBrains.dotCover.CommandLineTools.2019.3.4\TestReport\mergedReport.html" /ReportType="HTML"

出现以下错误-

Unhandled Exception:
System.UnauthorizedAccessException: Access to the path 'C:\Program Files (x86)\NUnit 2.6.2\bin\TestResult.xml' is denied.
   at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String 
msgPath, Boolean bFromProxy)

   at System.IO.StreamWriter..ctor(String path)
   at NUnit.ConsoleRunner.ConsoleUi.Execute(ConsoleOptions options)
   at NUnit.ConsoleRunner.Runner.Main(String[] args)

即使TestResult.xml文件不在该位置，也位于-

C:\Program Files (x86)\NUnit 2.6.2\doc\files\TestResult.xml

但是我复制了该文件并将其放入bin文件夹，但错误仍然存​​在。这个问题与权利有关吗？有什么办法摆脱这个？在此之后，执行既不会失败，也不会失败。

老实说，我建议将这些“ exe”路径添加到Windows系统路径或PowerShell环境路径。但是，按照我在评论中包括的链接，获取您到目前为止显示的内容：

PowerShell: Running Executables

5. 呼叫运营商＆

为什么：

[用于将字符串视为SINGLE命令。对处理有用空格。在PowerShell V2.0中，如果您正在运行7z.exe（7-Zip.exe）或另一个以数字开头的命令，您必须使用命令调用运算符＆。 PowerShell V3.0解析器现在就做更聪明，在这种情况下，您就不再需要＆。

详细信息：

运行命令，脚本或脚本块。呼叫操作员，也称为作为“调用运算符”，您可以运行存储在变量并由字符串表示。因为呼叫接线员会无法解析命令，无法解释命令参数

# Example:
& 'C:\Program Files\Windows Media Player\wmplayer.exe' "c:\videos\my home video.avi"  /fullscreen

当外部命令具有很多参数时，事情会变得棘手或参数或路径中有空格！

带空格，您必须嵌套引号，而结果却不是总是清楚！

在这种情况下，最好像这样将所有内容分开：

$CMD  =  'SuperApp.exe'
$arg1 =  'filename1'
$arg2 =  '-someswitch'
$arg3 =  'C:\documents and settings\user\desktop\some other file.txt'
$arg4 =  '-yetanotherswitch'
& $CMD $arg1 $arg2 $arg3 $arg4

# or same like that:
$AllArgs =  @('filename1',  '-someswitch', 'C:\documents and settings\user\desktop\some other file.txt', '-yetanotherswitch')
& 'SuperApp.exe' $AllArgs

因此，此更改将使您继续前进。同样，我不使用该工具，因此无法进行验证，因此您可能需要进行调整。
