That's pretty much exactly how we have things for CouchDB tests,
except that I wrote an Erlang source module that autoconf rewrites so
it knows where the build and source directories. Then in test code, I
just wrap file names with calls to source_file/1 and build_file/1 to
get the correct paths. This means that when writing tests you only
have to know if something is going to be part of the build/generated
by tests or is part of the source tarball.

I'm not exactly sure which copies you're referring to needing, but
another pattern I've seen is to just have a build target that copies
all files to the build directory so that the knowledge of paths
doesn't need to be considered. You can just treat everything as
relative to where your tests are run.
