If you run R CMD check mypkg, then you'll get a subdirectory created 
called mypkg.Rcheck.  If your package has tests, this subdir will itself 
have a tests subdir, and that will contain a .Rout file for your tests.

One way to monitor the tests would be to run them in the background and 
watch that file using "tail -f" (if you have tail, or can get it).
