Putting the tests there seems like a very reasonable solution to the immediate issue.  It contravenes the options to install (or not install) tests ("R CMD INSTALL --install-tests" loses meaning).  I'm going to update the structure of my vignette so that it detects if the tests are there and builds the vignette based on the existence of the tests (making it say "Please install the tests following these instructions...").

I'm immediately ok with reworking the directory structure and tests, but I think it would be preferable long run to:
Have R CMD BUILD gain an --install-args option so that installation arguments can be controlled (for situations like this and I'm sure others).

Thank you (and Happy Thanksgiving to those celebrating it),
