dotcover.exe中出现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生成覆盖率报告在我运行脚本之后-

$testRunner="C:Program Files (x86)NUnit 2.6.2binnunit-console.exe"
$testContainers="path/to/test1.dll","path/to/test2.dll"
$dotcover="D:JetBrains.dotCover.CommandLineTools.2019.3.4dotcover.exe"
foreach($test in $testContainers)
{
$testAssembly=Get-Item $test
$testName= $testAssembly.BaseName
&$dotcover cover /TargetExecutable=$testRunner /TargetArguments=$test /Output="D:JetBrains.dotCover.CommandLineTools.2019.3.4TestReport$testName.dcvr"
}
$testReports=$testContainer|%{
$testAssembly=Get-Item $test
$name= $testAssembly.BaseName
return ("D:JetBrains.dotCover.CommandLineTools.2019.3.4TestReport{0}.dcvr" -f $name)
}
$testReportArguments=[String]::Join(";",$testReports)
&$dotcover merge /Source="$testReportArguments" /Output="D:JetBrains.dotCover.CommandLineTools.2019.3.4TestReportmergedReport.dcvr" /ReportType="DCVR"

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

它给出了以下错误-

Unhandled Exception:
System.UnauthorizedAccessException: Access to the path 'C:Program Files (x86)NUnit 2.6.2binTestResult.xml' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

at NUnit.ConsoleRunner.ConsoleUi.Execute(ConsoleOptions options)
at NUnit.ConsoleRunner.Runner.Main(String[] args)

即使TestResult.xml文件不在那个位置，它也在-

C:Program Files (x86)NUnit 2.6.2docfilesTestResult.xml

但我复制了那个文件并将其放入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吗？并且在此之后，执行处于停止状态，既不失败也不通过。

任何时候你看到"访问被拒绝"，那么是的，这是权限/ACL问题。所以，你确实需要检查一下。

老实说，我建议将这些"exe"路径添加到Windows系统路径或PowerShell环境路径中。然而，根据我在评论中包含的链接：

PowerShell：运行可执行文件

5. 呼叫接线员&

原因：

用于将字符串视为SINGLE命令。有助于处理空间。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解析器立即执行更聪明的是，在这种情况下，你不需要&不再

详细信息：

运行命令、脚本或脚本块。呼叫接线员，也称为作为"调用运算符"，可以运行存储在变量，并用字符串表示。因为呼叫接线员不解析命令，它无法解释命令参数

# Example:
& 'C:Program FilesWindows Media Playerwmplayer.exe' "c:videosmy home video.avi"  /fullscreen

当外部命令有很多参数时，事情可能会变得棘手或者参数或路径中有空格！

有了空格，你必须嵌套引号，结果不是始终保持畅通！

在这种情况下，最好像这样分离所有内容：

$CMD  =  'SuperApp.exe'
$arg1 =  'filename1'
$arg2 =  '-someswitch'
$arg3 =  'C:documents and settingsuserdesktopsome other file.txt'
$arg4 =  '-yetanotherswitch'
& $CMD $arg1 $arg2 $arg3 $arg4
# or same like that:
$AllArgs =  @('filename1',  '-someswitch', 'C:documents and settingsuserdesktopsome other file.txt', '-yetanotherswitch')
& 'SuperApp.exe' $AllArgs

所以，这个改变应该会让你继续前进。同样，我不使用该工具，因此无法验证，因此您可能需要进行调整。
