Function New-CoverageReport () { <# .SYNOPSIS Creates a new coverage report based on the given PesterFileMap. .DESCRIPTION New-CoverageReport runs all Pester tests listed in the PesterFileMap. Source files without pester test will be marked as uncovered. It returns a coveralls.io REST API compatible Object. To upload the coverage report use Publish-CoverageReport. .PARAMETER PesterFileMap You need to provide a PesterFileMap created with New-PesterFileMap. .PARAMETER RepoToken Coveralls.io provides RepoTokens for grant access to the api upload methods. Therefore take a look at the repository page like: https://coveralls.io/github/<Github UserName>/<Repo Name>. .PARAMETER ModuleRoot New-CoverageReport uses relative file paths of the module. If you run New-CoverageReport not from the root directory of your module you need to provide the ModuleRoot path. This pattern is used to cut from the full file names to create the relative path. .INPUTS [None] .OUTPUTS [Hashtable] .EXAMPLE # Set location to your module root $FileMap = New-PesterFileMap -SourceRoot '.\src'-PesterRoot '.\tests' $CoverageReport = New-CoverageReport -PesterFileMap $FileMap -RepoToken 'ABCD1234' Publish-CoverageReport -CoverageReport $CoverageReport .NOTES File Name : New-CoverageReport.ps1 Author : Marco Blessing - marco.blessing@googlemail.com Requires : .LINK https://github.com/OCram85/PSCoverage #> [CmdletBinding()] Param( [Parameter(Mandatory=$True)] [ValidateNotNullOrEmpty()] [Hashtable]$PesterFileMap, [Parameter(Mandatory=$True)] [ValidateNotNullOrEmpty()] [String]$RepoToken, [Parameter(Mandatory=$False)] [ValidateNotNullOrEmpty()] [String]$ModuleRoot = $(Get-Location) ) BEGIN { $CoverReport = [PSCustomObject]@{ repo_token = $RepoToken commit_sha = (git log --format="%H" HEAD -1) git = Get-GitInfo service_name = 'appveyor' source_files = @() } } PROCESS { ForEach ($Item in $PesterFileMap.GetEnumerator() | Where-Object {$_.Value.Length -gt 0} ) { $Pest = Invoke-Pester -Script $Item.Value -CodeCoverage $Item.Name -PassThru -Quiet $Lines = (Get-Content -Path $Item.Name | Measure-Object).Count $CoverageArray = @() $Hits = 0 $Missed = 0 For ($LinePointer = 1; $LinePointer -le $Lines; $LinePointer++) { $Hits = ($Pest.CodeCoverage.HitCommands | Where-Object {$_.Line -eq $LinePointer} | Measure-Object).Count $Missed = ($Pest.CodeCoverage.MissedCommands | Where-Object {$_.Line -eq $LinePointer} | Measure-Object).Count Write-Verbose ("Line: {0} | Hits: {1} | Missed: {2}" -f $LinePointer, $Hits, $Missed) If ((-not $Hits -gt 0) -and (-not $Missed -gt 0)) { $CoverageArray += 'null' } Else { If ($Hits -gt 0) { $CoverageArray += $Hits } Else { If ($Missed -gt 0) { $CoverageArray += $Missed } } } } $CoverageSourceFile = [PSCustomObject]@{ name = $Item.Name.Replace($ModuleRoot,'').Replace('\','/') source_digest = (Get-FileHash -Path $Item.Name -Algorithm MD5).Hash coverage = $CoverageArray } If ($CoverageSourceFile.Name.StartsWith('/')) { $CoverageSourceFile.Name = $CoverageSourceFile.Name.Remove(0,1) } $CoverReport.source_files += $CoverageSourceFile } ForEach ($Item in $PesterFileMap.GetEnumerator() | Where-Object {$_.Value.Length -eq 0} ) { $Lines = (Get-Content -Path $Item.Name | Measure-Object).Count $CoverageArray = @() For ($LinePointer = 1; $LinePointer -le $Lines; $LinePointer++) { $CoverageArray += '0' } $CoverageSourceFile = [PSCustomObject]@{ name = $Item.Name.Replace($ModuleRoot,'').Replace('\','/') source_digest = (Get-FileHash -Path $Item.Name -Algorithm MD5).Hash coverage = $CoverageArray } If ($CoverageSourceFile.Name.StartsWith('/')) { $CoverageSourceFile.Name = $CoverageSourceFile.Name.Remove(0,1) } $CoverReport.source_files += $CoverageSourceFile } } END { Write-Output $CoverReport } } |
