title: Is there anyway to merge cobertura coverage xml reports together?
body: <p>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.</p>
  
  <p>So far I generate gcno files upon compilation and gcda files when source is used. Then call gcovr to get xml file.</p>
  
  <p>I would like to create coverage of each unit test (thus creating coverage xml for every unit test) and then merge these xml files into one xml file.</p>
  
  <p>Thanks!</p>
