Make OpenCover reports available in CruiseControl.NET

Question

I'm trying to integrate OpenCover with CruiseControl.NET. At this point I've modified by build system so it runs my nunit tests under OpenCover. I then generate Xml and Html reports from those using ReportGenerator.

Assuming it's possible to integrate the reports generated by ReportGenerator into the CruiseControl.NET webapp, how do I integrate the two?

NCover has it's own NCoverReporting task that can be used, but as I'm not running NCover I can't compare its output with the XML reports generated by OpenCover.

Related thoughts / questions:

• OpenCover generates an XML file by default, but is that XML file consumable by cc.net?
• ReportGenerator also generates XML, are they intended for something like cc.net?
• cc.net has a File-Merge publisher that merges logs, but I haven't yet found any documentation indicating which file formats are useful/used by cc.net.

ReportGenerator can also produce a HTML output those files (or index.html) should be easily linkable. – Pescara

Answer 1

I had this problem and I solved it with these steps, take into account that I'm using msbuild, so this will only work if you're using msbuild:

1. Add a Target for Coverage
2. Add a task to your build.proj for creating the OpenCoverage output (OpenCoverReport.xml)
3. Right after after that, add a task for creating the Summary report using ReportGenerator (reporttypes:XML). Like so: MSBuild Coverage Target Example
4. Create the XSL Transforms for creating HTML output with the Summary.xml, don't worry I wrote it already: For parsing assembly level coverage (in your build log output) use the following: XSLT for an Assembly level coverage report and for parsing the Class level coverage (detailed report) use the following: XSLT for a Class level coverage report
5. Add the buildReportBuildPlugin and xslReportBuildPlugin for creating both reports using the previous XSLT files in your dashboard.config file: Add this to the configuration
6. Merge the coverage report summary XML file to the Build output, in your ccnet.config file: add this to your configuration

Is it possible for you to post your entire configuration in the answer (would be easier to follow) - am trying to follow your steps but (1) and (2) are a little cryptic without examples... – Realistic

The link in step 3 it shows the result of step 1 and 2 as well. – Saddler

thank you (also realized that later). But for some reason the XSLTs that are linked here don't produce any results for me. Do they work? – Realistic

@ Marcel Valdez Orozco - Can you please clarify where the file in #6 came from? – Realistic

Answer 2

You could use External Links in your ccnet.config after exposing your report via IIS

   <externalLinks>
     <externalLink name="Code Coverage"     url="http://cc.net/coverage" /> 
   </externalLinks>

seems that he can do that with the coverage reports generated by ReportGenerator then. Having never used CC I couldn't make that call thanks for the update... a +1 from me and welcome to SO :) – Pescara
