function New-PSTGDatabaseCollationTest { <# .SYNOPSIS Function to create a collation test .DESCRIPTION The function will lookup the current collation of the database and create a test with that value .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 OutputPath Path to output the test to .PARAMETER Creator The person that created the tests. By default the command will get the environment username .PARAMETER TemplateFolder Path to template folder. By default the internal templates folder will be used .PARAMETER TestClass Test class name to use for the test .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-PSTGDatabaseCollationTest -Database DB1 -OutputPath "C:\Projects\DB1\TestBasic\" Create a new database collation test #> [CmdletBinding(SupportsShouldProcess)] param( [DbaInstanceParameter]$SqlInstance, [pscredential]$SqlCredential, [string]$Database, [Parameter(Mandatory)][string]$OutputPath, [string]$Creator, [string]$TemplateFolder, [string]$TestClass, [switch]$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 $Database return } # Test if the name of the test does not become too long if ($testName.Length -gt 128) { Stop-PSFFunction -Message "Name of the test is too long" -Target $testName } if (-not $TestClass) { $TestClass = "TestBasic" } $date = Get-Date -Format (Get-culture).DateTimeFormat.ShortDatePattern if (-not $Creator) { $Creator = $env:username } if (-not $TemplateFolder) { $TemplateFolder = Join-Path -Path ($script:ModuleRoot) -ChildPath "internal\templates" } if (-not (Test-Path -Path $TemplateFolder)) { try { $null = New-Item -Path $OutputPath -ItemType Directory } catch { Stop-PSFFunction -Message "Something went wrong creating the output directory" -Target $OutputPath -ErrorRecord $_ } } # 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 } $testName = "test If database has correct collation" $fileName = Join-Path -Path $OutputPath -ChildPath "$($testName).sql" # Import the template try { $script = Get-Content -Path (Join-Path -Path $TemplateFolder -ChildPath "DatabaseCollationTest.template") } catch { Stop-PSFFunction -Message "Could not import test template 'DatabaseCollationTest.template'" -Target $testName -ErrorRecord $_ } # Replace the markers with the content $script = $script.Replace("___TESTCLASS___", $TestClass) $script = $script.Replace("___TESTNAME___", $testName) $script = $script.Replace("___DATABASE___", $Database) $script = $script.Replace("___COLLATION___", $server.Databases[$Database].Collation) $script = $script.Replace("___CREATOR___", $creator) $script = $script.Replace("___DATE___", $date) # Write the test if ($PSCmdlet.ShouldProcess("$Database", "Writing Database Collation Test")) { try { Write-PSFMessage -Message "Creating collation test for '$Database'" $script | Out-File -FilePath $fileName [PSCustomObject]@{ TestName = $testName Category = "DatabaseCollation" Creator = $creator FileName = $fileName } } catch { Stop-PSFFunction -Message "Something went wrong writing the test" -Target $testName -ErrorRecord $_ } } } } |
