function Invoke-PSQualityCheck { <# .SYNOPSIS Invoke the PSQualityCheck tests .DESCRIPTION Invoke a series of Pester-based quality tests on the passed files .PARAMETER Path A string array containing paths to check for testable files .PARAMETER File A string array containing testable files .PARAMETER Recurse A switch specifying whether or not to recursively search the path specified .PARAMETER ScriptAnalyzerRulesPath A path the the external PSScriptAnalyzer rules .PARAMETER ShowCheckResults Show a summary of the Check results at the end of processing Note: this cannot be used with -Passthru .PARAMETER ExportCheckResults Exports the Check results at the end of processing to file .PARAMETER Passthru Returns the Check results objects back to the caller Note: this cannot be used with -ShowCheckResults .PARAMETER PesterConfiguration A Pester configuration object to allow configuration of Pester .PARAMETER Include An array of test tags to run .PARAMETER Exclude An array of test tags to not run .PARAMETER ProjectPath A path to the root of a Project .EXAMPLE Invoke-PSQualityCheck -Path 'C:\Scripts' This will call the quality checks on single path .EXAMPLE Invoke-PSQualityCheck -Path 'C:\Scripts' -Recurse This will call the quality checks on single path and sub folders .EXAMPLE Invoke-PSQualityCheck -Path @('C:\Scripts', 'C:\MoreScripts') This will call the quality checks with multiple paths .EXAMPLE Invoke-PSQualityCheck -File 'C:\Scripts\Script.ps1' This will call the quality checks with single script file .EXAMPLE Invoke-PSQualityCheck -File 'C:\Scripts\Script.psm1' This will call the quality checks with single module file .EXAMPLE Invoke-PSQualityCheck -File 'C:\Scripts\Script.psd1' This will call the quality checks with single datafile file Note: The datafile test will fail as it is not a file that is accepted for testing .EXAMPLE Invoke-PSQualityCheck -File @('C:\Scripts\Script.ps1','C:\Scripts\Script2.ps1') This will call the quality checks with multiple files. Files can be either scripts or modules .EXAMPLE Invoke-PSQualityCheck -File 'C:\Scripts\Script.ps1' -ScriptAnalyzerRulesPath 'C:\ScriptAnalyzerRulesPath' This will call the quality checks with single file and the extra PSScriptAnalyzer rules .EXAMPLE Invoke-PSQualityCheck -Path 'C:\Scripts' -ShowCheckResults This will display a summary of the checks performed (example below uses sample data): Name Files Tested Total Passed Failed Skipped ---- ------------ ----- ------ ------ ------- Module Tests 2 14 14 0 0 Extracting functions 2 2 2 0 0 Extracted function script tests 22 330 309 0 21 Total 24 346 325 0 21 For those who have spotted that the Total files tested isn't a total of the rows above, this is because the Module Tests and Extracting function Tests operate on the same file and are then not counted twice .LINK Website: https://github.com/andrewrdavidson/PSQualityCheck SonarQube rules are available here: https://github.com/indented-automation/ScriptAnalyzerRules #> [CmdletBinding()] [OutputType([System.Void], [HashTable], [System.Object[]])] param ( [Parameter(Mandatory = $true, ParameterSetName = "Path")] [String[]]$Path, [Parameter(Mandatory = $true, ParameterSetName = "File")] [String[]]$File, [Parameter(Mandatory = $true, ParameterSetName = "ProjectPath")] [String]$ProjectPath, [Parameter(Mandatory = $false, ParameterSetName = "Path")] [switch]$Recurse, [Parameter(Mandatory = $false)] [String[]]$ScriptAnalyzerRulesPath, [switch]$ShowCheckResults, [switch]$ExportCheckResults, [switch]$Passthru, [Parameter(Mandatory = $false)] [System.Object]$PesterConfiguration, [Parameter(Mandatory = $false)] [String[]]$Include, [Parameter(Mandatory = $false)] [String[]]$Exclude ) Set-StrictMode -Version Latest #
