<# .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-DbatoolsConfig -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-DbatoolsConfig -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 ConfigFile The path to the exported dbachecks config file. .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://dbachecks.readthedocs.io/en/latest/functions/Invoke-DbcCheck/ .EXAMPLE Invoke-DbcCheck -Tag Backup -SqlInstance sql2016 Runs all of the checks tagged Backup against the sql2016 instance .EXAMPLE Invoke-DbcCheck -Tag RecoveryModel -SqlInstance sql2017, sqlcluster -SqlCredential (Get-Credential sqladmin) Runs the Recovery model check against the SQL instances sql2017, sqlcluster using the sqladmin SQL login with the password provided interactively .EXAMPLE Invoke-DbcCheck -Check Database -ExcludeCheck AutoShrink -ConfigFile \\share\repo\prod.json Runs all of the checks tagged Database except for the AutoShrink check against the SQL Instances set in the config under app.sqlinstance Imports configuration file, \\share\repo\prod.json, prior to executing checks. .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 Runs the Suspect Pages and Last Backup checks against the SQL Instances sql2016, sql2017, sql2008, sql2008\express after setting them in the configuration .EXAMPLE Invoke-DbcCheck -SqlInstance sql2017 -Tags SuspectPage, LastBackup -Show Summary -PassThru | Update-DbcPowerBiDataSource Start-DbcPowerBi Runs the Suspect Page and Last Backup checks against the SQL Instances set in the config under app.sqlinstance only showing the summary of the results of the checks. It then updates the source json for the XML which is stored at C:\Windows\temp\dbachecks\ and then opens the PowerBi report in PowerBi Desktop .EXAMPLE Get-Help -Name Invoke-Pester -Examples Want to get super deep? You can look at Invoke-Pester's example's and run them against Invoke-DbcCheck since it's a wrapper. https://github.com/pester/Pester/wiki/Invoke-Pester Describe about_Pester #> #TODO the help is probably not correct function Invoke-DbcCheck { [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSAvoidGlobalVars', '', Justification = 'Because scoping is hard')] [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseDeclaredVarsMoreThanAssignments', '', Justification = 'Because its set to the global var')] [CmdletBinding(DefaultParameterSetName = 'Default')] param ( [Alias('Path', 'relative_path')] [object[]]$Script, [Alias('Name')] [string[]]$TestName, [switch]$EnableExit, [Parameter(Position = 0)] [Alias('Tags', 'Tag', 'Checks')] [string[]]$Check, [AllowEmptyCollection()] [Alias('ExcludeTags', 'ExcludeTag', 'ExcludeChecks')] [string[]]$ExcludeCheck = (Get-PSFConfigValue -FullName 'dbachecks.command.invokedbccheck.excludecheck' -Fallback @()), [switch]$PassThru, [DbaInstance[]]$SqlInstance, [DbaInstance[]]$ComputerName, [PSCredential]$SqlCredential, [PSCredential]$Credential, [object[]]$Database, [object[]]$ExcludeDatabase = (Get-PSFConfigValue -FullName 'dbachecks.command.invokedbccheck.excludedatabase' -Fallback @()), [string[]]$Value, [string]$ConfigFile, [object[]]$CodeCoverage = @(), [string]$CodeCoverageOutputFile, [ValidateSet('JaCoCo')] [string]$CodeCoverageOutputFileFormat = 'JaCoCo', [switch]$Strict, [Parameter(Mandatory = $true, ParameterSetName = 'NewOutputSet')] [string]$OutputFile, [ValidateSet('NUnitXml')] [string]$OutputFormat, [switch]$AllChecks, [switch]$Quiet, [ValidateSet('None', 'Minimal', 'Detailed', 'Default', 'Passed', 'Failed', 'Pending', 'Skipped', 'Inconclusive', 'Describe', 'Context', 'Summary', 'Header', 'Fails', 'All', 'Diagnostic')] #None, Default,Passed, Failed, Pending, Skipped, Inconclusive, Describe, Context, Summary, Header, All, Fails.
