I’ve been trying to get common_test working with code coverage and one of the more esoteric (annoying!?) issues I’ve run into is that the cover tool doesn’t work properly with packages. There is a workaround, which I mention here, but that will only fix the problem with cover. In addition to this, the ct_cover module will produce reports without proper links to coverage info unless you copy the source code over the corresponding ebin directories. It would be *really* nice if this got sorted out.
