Question

我有一个工作的PowerShell脚本，用于安装当前显示可安装在SCCM客户端中的任何补丁，但我发现没有办法构建一个pester测试来验证脚本是否按预期工作而没有实际安装补丁。

在测试结束时是否可以以某种方式创建，安装，测试然后卸载虚拟补丁？我不知道这是否可能。

安装可用补丁的脚本：

Function Install-SCCMAvailablePatches {
  [CmdletBinding()]
  param(
    [Parameter( 
      Mandatory = $False,
      ValueFromPipelineByPropertyName = $True,
      HelpMessage = "Reboot Server if needed? Default: True")]
    [ValidateNotNullOrEmpty()]
    [string]
    $Reboot = $True
  )

  begin {
    Write-Verbose "Install-SCCMAvailablePatches: Started"
  }

  process {
    try {  ([wmiclass]'ROOT\ccm\ClientSDK:CCM_SoftwareUpdatesManager').InstallUpdates([System.Management.ManagementObject[]] (Get-WmiObject -Query 'SELECT * FROM CCM_SoftwareUpdate' -namespace 'ROOT\ccm\ClientSDK')) 
        while (Not((Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities' -list).DetermineIfRebootPending().RebootPending)) {
            $Time = (get-date).ToShortTimeString()
            Write-Verbose "Still Patching @ $Time"
            Start-Sleep -s 60 }
        if ($Reboot -eq $True) {
            if ((Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities' -list).DetermineIfRebootPending().RebootPending) {
               (Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities' -list).RestartComputer()
            }      
        }
    }
    catch {
      Write-Error -Message "Something went wrong with Install-SCCMAvailablePatches."
    }
  }

  end {
    Write-Verbose "Install-SCCMAvailablePatches: Completed"
  }      
} #End Install-SCCMAvailablePatches

您应该重新编写您的功能，以便首先打开它进行测试。 Pester鼓励测试驱动开发，这意味着您定义输入，定义输出，编写测试以确保结果，然后编写代码。

Function Install-SCCMAvailablePatches
{
    [CmdletBinding()]
    Param(
        [Parameter(Mandatory)]
        [ValidateScript({
            <# Test conditions #>
        })]
        [System.Management.ManagementObject]$UpdateManager,
        [Switch]$Reboot
    )

    Begin
    {
        Write-Verbose "Install-SCCMAvailablePatches: Started"
    }

    Process
    {
        Try
        {
            $UpdateManager.InstallUpdates(
                @(Get-WmiObject -Query 'SELECT * FROM CCM_SoftwareUpdate' -Namespace 'ROOT\ccm\ClientSDK')
            )

            $Client = Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities'
            While (-not $Client.DetermineIfRebootPending().RebootPending)
            {
                Write-Verbose (Get-Date -UFormat 'Still patching @ %H:%M')
                Start-Sleep -Seconds 60
            }

            If ($Reboot -and $Client.DetermineIfRebootPending().RebootPending)
            {
                $Client.RestartComputer()
            }
        }
        Catch
        {
            Write-Error -Message "Something went wrong with Install-SCCMAvailablePatches."
        }
    }  

    End
    {
        Write-Verbose "Install-SCCMAvailablePatches: Completed"
    }      
}

现在，您可以在Pester测试中模拟作为参数传递的wmi对象与您自己的对象/属性。
