阅读更多关于 Is there anyway to merge cobertura coverage xml reports together?

问题 I have c++/c application with a lots of unit tests. I would like to get overall coverage and also individual coverage of each test with condition that each test can be run only once. Format of coverage must be xml (cobertura xml) for jenkins cobertura plugin to process. So far I generate gcno files upon compilation and gcda files when source is used. Then call gcovr to get xml file. I would like to create coverage of each unit test (thus creating coverage xml for every unit test) and then

I have the .gcda and .gcno files in a folder, from which I am running the below command. $ gcovr -r . and the result is as below if I run gcov on the gcda files I get the proper coverage value. After a tedious search in multiple forums and countless experiments, finally I figured out the issue and resolved it. Two things are important to get the proper output from gcovr. One is from where the gcovr is executed and other is the root directory path. gcovr should be executed from the folder where the .gcda and .gcno files exist. And the root path is the folder where the source files(.c or .cpp)

I'm using gcovr to generate a XML that is then parsed by Sonar: gcovr -x -b -r . --object-directory=debug/test > coverage_report.xml I have three sets of gcda and gcno files, but I don't know how to generate a global report of them. Is there any way to do that ?
