VStest code coverage report in jenkins

Question

I am setting CI for .Net project using Jenkins.

I used MSTest Plugin and VStestrunner plugin to run test. Now I have .trx file and .Coverage file I am facing problem in displaying code coverage report

Please help me is you know any plugin to do this.

Answer 1

I have struggled this for a long time, finally I found we can use "CodeCoverage.exe" "ReportGenarator.exe" and "Cobertura plugin" to show perfect coverage report.

"ReportGenarator.exe" can be get from https://github.com/danielpalme/ReportGenerator/releases

• first use "CodeCoverage.exe" translate .coverage file to .xml file

    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Team Tools\Dynamic Code Coverage Tools\CodeCoverage.exe" analyze -output:./TestResults/coverage.xml ./TestResults/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.coverage"

• second use ReportGenarator.exe translate vstest xml format to Cobertura xml format

    "ReportGenerator_4.4.7\net47\ReportGenerator.exe" -reports:./TestResults/coverage.xml -targetdir:./TestResults -reporttypes:cobertura

• finally install cobertura plugin use it to collect xml file, here give a pipeline useage example

    post {
        always {
            cobertura coberturaReportFile: './TestResults/Cobertura.xml'
        }
    }

• the result just like this

Answer 2

To display the coverage report you need to convert it in XML format and use MSTest Plugin to publish the report. MSTest Plugin recommends (https://wiki.jenkins-ci.org/display/JENKINS/MSTest+Plugin) to use third party application to convert in XML format and powershell (you will need to install pugin for it) to run it.

However you can convert it with PowerShell only. There is example of script:

$coverageFile = $(get-ChildItem -Path .\TestResults -Recurse -Include *coverage)[0]
$xmlCoverageFile = ".\TestResults\vstest.coveragexml"

Add-Type -path "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Coverage.Analysis.dll"

[string[]] $executablePaths = @($coverageFile)
[string[]] $symbolPaths = @()

$info = [Microsoft.VisualStudio.Coverage.Analysis.CoverageInfo]::CreateFromFile($coverageFile, $executablePaths, $symbolPaths);
$data = $info.BuildDataSet()

$data.WriteXml($xmlCoverageFile)

You maybe will need to fix the path to Microsoft.VisualStudio.Coverage.Analysis.dll according to your VS version.
