Hi,
I am working on java GUI testing and I am using EMMA coverage reports in HTML format .
I faced problem with getting the overall code coverage, every once I run and stop GUI I get new report with new values.
I.e: run EMMA on GUI/part1 stop GUI and get new coverage report, run EMMA report another time but on part2 and stop GUI. I don't need new report but I need to merge 2 reports.
So is there a way to merge the new generated HTML EMMA report with old one or to merge 2 EMMA report.

Thanks,
