Can any one explain me how could i calculate code coverage percentage, number of lines covered and other useful information by xml.
I am using Xslt for converting it into html , i can not use Report generator tool for this purpose.
Thanks in advance.
Solution
A line of code is covered by a SequencePoint.
A visited SequencePoint has a vc > 0
So the total coverage for the coverage run is
count( SequencePoint where vc > 0) * 100 / count(SequencePoint)
You can then fine tune the results by restricting your search on a per module/type/method basis
BranchPoint and MethodPoint results can be calculated in a similar way
OTHER TIPS
Take a look at ReportGenerator: https://github.com/danielpalme/ReportGenerator With this tool you can convert your OpenCover report to HTML, XML and Latex
Perhaps this helps: Make OpenCover reports available in CruiseControl.NET
