function Invoke-DbcCheck { <# .SYNOPSIS Invoke-DbcCheck is a SQL-centric Invoke-Pester wrapper .DESCRIPTION The Invoke-DbcCheck function runs Pester tests, including *.Tests.ps1 files and Pester tests in PowerShell scripts. Extended description about Pester: Get-Help -Name Invoke-Pester .PARAMETER Check Runs only tests in Describe blocks with the specified Tag parameter values. Wildcard characters and Tag values that include spaces or whitespace characters are not supported. When you specify multiple Tag values, Invoke-DbcCheck runs tests that have any of the listed tags (it ORs the tags). However, when you specify TestName and Tag values, Invoke-DbcCheck runs only describe blocks that have one of the specified TestName values and one of the specified Tag values. If you use both Tag and ExcludeTag, ExcludeTag takes precedence. .PARAMETER ExcludeCheck Omits tests in Describe blocks with the specified Tag parameter values. Wildcard characters and Tag values that include spaces or whitespace characters are not supported. When you specify multiple ExcludeTag values, Invoke-DbcCheck omits tests that have any of the listed tags (it ORs the tags). However, when you specify TestName and ExcludeTag values, Invoke-DbcCheck omits only describe blocks that have one of the specified TestName values and one of the specified Tag values. If you use both Tag and ExcludeTag, ExcludeTag takes precedence .PARAMETER SqlInstance A list of SQL Servers to run the tests against. If this is not provided, it will be gathered from: Get-DbaConfig -Name app.sqlinstance .PARAMETER ComputerName A list of computers to run the tests against. If this is not provided, it will be gathered from: Get-DbaConfig -Name app.computername .PARAMETER SqlCredential Alternate SQL Server-based credential. .PARAMETER Credential Alternate Windows credential. .PARAMETER Database A list of databases to include if your check is database centric. .PARAMETER ExcludeDatabase A list of databases to exclude if your check is database centric. .PARAMETER PassThru Returns a custom object (PSCustomObject) that contains the test results. By default, Invoke-DbcCheck writes to the host program, not to the output stream (stdout). If you try to save the result in a variable, the variable is empty unless you use the PassThru parameter. To suppress the host output, use the Quiet parameter. .PARAMETER OutputFormat The format of output. Currently, only NUnitXML is supported. .PARAMETER Strict Makes Pending and Skipped tests to Failed tests. Useful for continuous integration where you need to make sure all tests passed. .PARAMETER AllChecks In the unlikely event that you'd like to run all checks, specify -AllChecks. These checks still confirm to the skip settings in Get-DbcConfig. .PARAMETER Quiet The parameter Quiet is deprecated since Pester v. 4.0 and will be deleted in the next major version of Pester. Please use the parameter Show with value 'None' instead. .PARAMETER Show Customizes the output Pester writes to the screen. Available options are None Default Passed Failed Pending Skipped Inconclusive Describe Context Summary Header All Fails The options can be combined to define presets. Common use cases are: None - to write no output to the screen. All - to write all available information (this is default option). Fails - to write everything except Passed (but including Describes etc.). A common setting is also Failed, Summary, to write only failed tests and test summary. This parameter does not affect the PassThru custom object or the XML output that is written when you use the Output parameters. .PARAMETER Value A value.. it's hard to explain .PARAMETER Script Get-Help -Name Invoke-Pester -Parameter Script .PARAMETER TestName Get-Help -Name Invoke-Pester -Parameter TestName .PARAMETER EnableExit Get-Help -Name Invoke-Pester -Parameter EnableExit .PARAMETER OutputFile Get-Help -Name Invoke-Pester -Parameter OutputFile .PARAMETER CodeCoverage Get-Help -Name Invoke-Pester -Parameter CodeCoverage .PARAMETER PesterOption Get-Help -Name Invoke-Pester -Parameter PesterOption .PARAMETER CodeCoverageOutputFile Get-Help -Name Invoke-Pester -Parameter CodeCoverageOutputFile .PARAMETER CodeCoverageOutputFileFormat Get-Help -Name Invoke-Pester -Parameter CodeCoverageOutputFileFormat .LINK https://github.com/pester/Pester/wiki/Invoke-Pester Describe about_Pester .EXAMPLE # Set the servers you'll be working with Set-DbcConfig -Name app.sqlinstance -Value sql2016, sql2017, sql2008, sql2008\express Set-DbcConfig -Name app.computername -Value sql2016, sql2017, sql2008 # Look at the current configs Get-DbcConfig # Invoke a few tests Invoke-DbcCheck -Tags SuspectPage, LastBackup Does this and that .EXAMPLE Invoke-DbcCheck -Tag Backup -SqlInstance sql2016 Invoke-DbcCheck -Tag RecoveryModel -SqlInstance sql2017, sqlcluster -SqlCredential (Get-Credential sqladmin) Does this .EXAMPLE Invoke-DbcCheck -Check Database -ExcludeCheck AutoShrink Does that .EXAMPLE # Run checks and export its JSON Invoke-DbcCheck -SqlInstance sql2017 -Tags SuspectPage, LastBackup -Show Summary -PassThru | Update-DbcPowerBiDataSource # Launch Power BI then hit refresh Start-DbcPowerBi Does that .EXAMPLE Invoke-DbcCheck -SqlInstance sql2017 -Tags SuspectPage, LastBackup -OutputFormat NUnitXml -PassThru | Send-DbcMailMessage -To clemaire@dbatools.io -From nobody@dbachecks.io -SmtpServer smtp.ad.local .EXAMPLE Get-Help -Name Invoke-Pester -Examples Want to get super deep?
