################################################################################ <# .SYNOPSIS Asserts and improves unit-tests of a specified GenXdev cmdlet. .DESCRIPTION This function helps maintain and improve unit tests for GenXdev cmdlets by: 1. Creating test files if they don't exist 2. Opening the cmdlet in VS Code 3. Preparing and applying AI prompts for test generation/improvement 4. Managing test execution workflow .PARAMETER CmdletName The name of the cmdlet to improve unit-tests for. Required. .PARAMETER Prompt Custom AI prompt text to use for test generation. Optional. .PARAMETER EditPrompt Switch to only edit the AI prompt without modifying the cmdlet. Optional. .PARAMETER AssertFailedTest Switch to indicate assertion of a failed test. Optional. .EXAMPLE Assert-GenXdevCmdletTests -CmdletName "Get-GenXDevModuleInfo" -EditPrompt .EXAMPLE improvecmdlettests Get-GenXDevModuleInfo -AssertFailedTest #> function Assert-GenXdevCmdletTests { [CmdletBinding()] [System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseSingularNouns", "")] [Alias("improvecmdlettests")] param( ######################################################################## [Alias("cmd")] [parameter( Mandatory = $true, Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = "The name of the cmdlet to improve unit-tests for" )] [ValidateNotNullOrEmpty()] [string] $CmdletName, ######################################################################## [parameter( Position = 1, Mandatory = $false, HelpMessage = "Custom AI prompt text to use" )] [AllowEmptyString()] [string] $Prompt = "", ######################################################################## [parameter( Mandatory = $false, HelpMessage = "Switch to only edit the AI prompt" )] [switch] $EditPrompt, ######################################################################## [parameter( Mandatory = $false, HelpMessage = "Indicates to assert a failed test" )] [switch] $AssertFailedTest ) begin { # get target cmdlet information including script position $cmdlet = Get-GenXDevCmdlets -CmdletName $CmdletName # validate cmdlet exists if ($null -eq $cmdlet) { throw "Could not find GenXdev cmdlet $CmdletName" } # store cmdlet name for later use $CmdletName = $cmdlet.Name # determine which prompt template to use based on test file existence $PromptKey = "CreateUnitTests" $functionDefinition = [System.IO.File]::ReadAllText($cmdlet.ScriptFilePath) if ([IO.File]::Exists($cmdlet.ScriptTestFilePath) -and (-not [string]::IsNullOrWhiteSpace($functionDefinition))) { $PromptKey = $AssertFailedTest ?
