how to merge all opencover coverage files into one coverage file

Question

I am looking how to merge the test projects coverage file into one coverage file for .net core using Coverlet. I know we can do it using Report Generator but the output format of the Report generator is in Xml format which is not understandable by SonarQube. So I could like to know is there a way to get one Coverage file which can be in opencover format using Coverlet.

I have created a coverage files for multiple test projects using Coverlet package. My question is can we able to merge all coverage files into one coverage file without using Report Generator. Can I have an example how to do it.

Any help is appreciated. Thank you in advance.

Answer 1

ReportGenerator is not able to generate an OpenCover file as output.
But ReportGenerator is capable to generate a Cobertura file with all input files merged.
Sonarcube should be able to handle the Cobertura file.

Perhaps you need a plugin:
