.SYNOPSIS EXPERIMENTAL: Use Robocopy or Copy-Item for folder and file dependencies, respectively. .DESCRIPTION EXPERIMENTAL: Use Robocopy or Copy-Item for folder and file dependencies, respectively. Runs in the current session (i.e. as the current user) Relevant Dependency metadata: DependencyName (Key): The key for this dependency is used as the URL. This can be overridden by 'Source' Name: Optional file name for the downloaded file. Defaults to parsing filename from the URL Target: The folder to copy the source to. If the source is a file, we adjust this in Robocopy to append the source folder name. Source: The source folder or file to copy .PARAMETER Dependency Dependency to run .PARAMETER PSDependAction Test, Install, or Import the module. Defaults to Install Test: Return true or false on whether the dependency is in place IMPORTANT: If a folder exists, return $True, whether the contents are the same or not If a file exists, we check the hash Install: Install the dependency Import: Import the dependency 'Target'. Override with ImportPath .PARAMETER ImportPath If specified with PSDependAction Import, we import this path, instead of the target (or target parent if target is a file) .PARAMETER Force If specified, and target is a folder, overwrite the target .PARAMETER Mirror If specified and the target is a folder, we effectively call robocopy /MIR (Can remove folders/files...) .EXAMPLE @{ 'notepad' = @{ DependencyType = 'FileSystem' Source = 'C:\windows\notepad.exe' Target = 'C:\PSDependPesterTest' } } # Copy C:\Windows\Notepad.exe to C:\PSDependPesterTest\notepad.exe .EXAMPLE @{ 'psams' = @{ DependencyType = 'FileSystem' Source = '\\FileServer\powershell\modules\psams' Target = 'C:\ProjectX' } } # Copy psams module to C:\ProjectX\psams #> [cmdletbinding()] param ( [PSTypeName('PSDepend.Dependency')] [psobject[]] $Dependency, [ValidateSet('Test', 'Install', 'Import')] [string[]]$PSDependAction = @('Install'), [string]$ImportPath ) # Extract data from Dependency $DependencyName = $Dependency.DependencyName $Name = $Dependency.Name $Target = $Dependency.Target $Sources = @($Dependency.Source) $TestOutput = @() foreach ($Source in @($Sources)) { if (-not (Test-Path $Source)) { if (-not $PSDependAction -like 'Test') { Write-Error "Skipping $DependencyName, could not find source [$Sources] due to error:" } continue } $IsContainer = ( Get-Item $Source ).PSIsContainer # Resolve PSDrives. $Target = $ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath($Target) $Source = $ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath($Source) if ($IsContainer) { $Folder = Split-Path $Source -Leaf $Target = Join-Path $Target $Folder if (-not $ImportPath) { $ImportPath = $Target } # We don't test equality for containers yet if (Test-Path $Target) { $TestOutput += $true } else { $TestOutput += $false } if ($PSDependAction -like 'Install') { # TODO: Add non Windows equivalent...
