.SYNOPSIS This script will invoke Pester tests, then serialize XML results and pull them in appveyor.yml .DESCRIPTION Internal function that creates SMO server object. .PARAMETER Finalize If Finalize is specified, we collect XML output, upload tests, and indicate build errors .PARAMETER PSVersion The version of PS .PARAMETER TestFile The output file .PARAMETER ProjectRoot The appveyor project root .PARAMETER ModuleBase The location of the module .PARAMETER IncludeCoverage Calculates coverage and sends it to codecov.io .EXAMPLE .\appveyor.pester.ps1 Executes the test .EXAMPLE .\appveyor.pester.ps1 -Finalize Finalizes the tests #> param ( [switch]$Finalize, $PSVersion = $PSVersionTable.PSVersion.Major, $TestFile = "TestResultsPS$PSVersion.xml", $ProjectRoot = $ENV:APPVEYOR_BUILD_FOLDER, $ModuleBase = $ProjectRoot, [switch]$IncludeCoverage ) # Move to the project root Set-Location $ModuleBase # required to calculate coverage $global:dbatools_dotsourcemodule = $true Remove-Module dbatools -ErrorAction Ignore Import-Module "$ModuleBase\dbatools.psm1" -DisableNameChecking function Get-CoverageIndications($Path, $ModuleBase) { # takes a test file path and figures out what to analyze for coverage (i.e. dependencies) $CBHRex = [regex]'(?smi)<#(.*)#>' $everything = (Get-Module dbatools).ExportedCommands.Values $everyfunction = $everything.Name $funcs = @() $leaf = Split-Path $path -Leaf # assuming Get-DbaFoo.Tests.ps1 wants coverage for "Get-DbaFoo" # but allowing also Get-DbaFoo.one.Tests.ps1 and Get-DbaFoo.two.Tests.ps1 $func_name += ($leaf -replace '^([^.]+)(.+)?.Tests.ps1', '$1') if ($func_name -in $everyfunction) { $funcs += $func_name $f = $everything | Where-Object Name -eq $func_name $source = $f.Definition $CBH = $CBHRex.match($source).Value $cmdonly = $source.Replace($CBH, '') foreach($e in $everyfunction) { # hacky, I know, but every occurrence of any function plus a space kinda denotes usage !?
