Subject Re: Code coverage with debug logs: 100% branch coverage not possible?...
Date Wed, 12 Feb 2014 20:36:27 GMT
IIRC, there should be an option in Emma/Cobertura that allows you to
exclude coverage on certain classes. So if you can exclude your log4j
classes (you don't really want to test your logging, do you?), then you
should be able to raise your percentage.
