function New-PSTGProcedureParameterTest { <# .SYNOPSIS Function to create procedure tests .DESCRIPTION The function will collect the parameter(s) of the procedure(s) and create the test .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Database The database or databases to add. .PARAMETER Procedure Procedure(s) to create tests for .PARAMETER OutputPath Path to output the test to .PARAMETER TemplateFolder Path to template folder. By default the internal templates folder will be used .PARAMETER InputObject Takes the parameters required from a Procedure object that has been piped into the command .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .EXAMPLE New-PSTGProcedureParameterTest -Procedure $procedure -OutputPath $OutputPath Create a new procedure parameter test .EXAMPLE $procedures | New-PSTGProcedureParameterTest -OutputPath $OutputPath Create the tests using pipelines #> [CmdletBinding(SupportsShouldProcess)] param( [DbaInstanceParameter]$SqlInstance, [pscredential]$SqlCredential, [string]$Database, [string[]]$Procedure, [string]$OutputPath, [string]$TemplateFolder, [parameter(ParameterSetName = "InputObject", ValueFromPipeline)] [object[]]$InputObject, [switch]$EnableException ) begin { # Check parameters if (-not $SqlInstance) { Stop-PSFFunction -Message "Please enter a SQL Server instance" -Target $SqlInstance return } if (-not $Database) { Stop-PSFFunction -Message "Please enter a database" -Target $Database return } # Check the output path if (-not $OutputPath) { Stop-PSFFunction -Message "Please enter an output path" return } if (-not (Test-Path -Path $OutputPath)) { Stop-PSFFunction -Message "Could not access output path" -Category ResourceUnavailable -Target $OutputPath } # Check the template folder if (-not $TemplateFolder) { $TemplateFolder = Join-Path -Path ($script:ModuleRoot) -ChildPath "internal\templates" } if (-not (Test-Path -Path $TemplateFolder)) { Stop-PSFFunction -Message "Could not find template folder" -Target $OutputPath } $date = Get-Date -Format (Get-culture).DateTimeFormat.ShortDatePattern $creator = $env:username # Connect to the server try { $server = Connect-DbaInstance -SqlInstance $Sqlinstance -SqlCredential $SqlCredential } catch { Stop-PSFFunction -Message "Could not connect to '$Sqlinstance'" -Target $Sqlinstance -ErrorRecord $_ -Category ConnectionError return } # Check if the database exists if ($Database -notin $server.Databases.Name) { Stop-PSFFunction -Message "Database cannot be found on '$SqlInstance'" -Target $Database } } process { if (Test-PSFFunctionInterrupt) { return } if (-not $InputObject -and -not $Procedure -and -not $SqlInstance) { Stop-PSFFunction -Message "You must pipe in an object or specify a Procedure" return } if ($Procedure) { $InputObject = $server.Databases[$Database].StoredProcedures | Select-Object Schema, Name, Parameters | Where-Object Name -in $Procedure } else { $InputObject = $server.Databases[$Database].StoredProcedures | Select-Object Schema, Name, Parameters, IsSystemObject | Where-Object IsSystemObject -eq $false } foreach ($input in $InputObject) { $testName = "test If stored procedure $($input.Schema).$($input.Name) has the correct parameters Expect Success" # Test if the name of the test does not become too long if ($testName.Length -gt 128) { Stop-PSFFunction -Message "Name of the test is too long" -Target $testName } $fileName = Join-Path -Path $OutputPath -ChildPath "$($testName).sql" $date = Get-Date -Format (Get-culture).DateTimeFormat.ShortDatePattern $creator = $env:username # Get the parameters $parameters = $input.Parameters if ($parameters.Count -ge 1) { # Import the template try { $script = Get-Content -Path (Join-Path -Path $TemplateFolder -ChildPath "ProcedureParameterTest.template") } catch { Stop-PSFFunction -Message "Could not import test template 'ProcedureParameterTest.template'" -Target $testName -ErrorRecord $_ } $paramTextCollection = @() # Loop through the parameters foreach ($parameter in $parameters) { $paramText = "`t('$($parameter.Name)', '$($parameter.DataType.Name)', $($parameter.DataType.MaximumLength), $($parameter.DataType.NumericPrecision), $($parameter.DataType.NumericScale))" $paramTextCollection += $paramText } # Replace the markers with the content $script = $script.Replace("___TESTNAME___", $testName) $script = $script.Replace("___SCHEMA___", $input.Schema) $script = $script.Replace("___NAME___", $input.Name) $script = $script.Replace("___CREATOR___", $creator) $script = $script.Replace("___DATE___", $date) $script = $script.Replace("___PARAMETERS___", ($paramTextCollection -join ",`n") + ";") # Write the test if ($PSCmdlet.ShouldProcess("$($input.Schema).$($input.Name)", "Writing Procedure Parameter Test")) { try { Write-PSFMessage -Message "Creating procedure parameter test for procedure '$($input.Schema).$($input.Name)'" $script | Out-File -FilePath $fileName [PSCustomObject]@{ TestName = $testName Category = "ProcedureParameter" Creator = $creator FileName = $fileName } } catch { Stop-PSFFunction -Message "Something went wrong writing the test" -Target $testName -ErrorRecord $_ } } } else { Write-PSFMessage -Message "Procedure $($input.Schema).$($input.Name) does not have any parameters.
