Hello David, Unfortunately there is no really good way for CTest to guess all the lines from the source code. We use GCov output, which contains the actual lines and their corresponding coverage. If the file is not used, then GCov will not contain any information and therefore it will be ignored.
So, as I said, we cannot just take the whole file, since the file will contain comments, empty lines, etc. I guess we could write a simple C++ parser (no such thing) that would parse files and remove comments and other useless things, but that would be way too complicated. Hope that helps.
