You're really not supposed to run QMTest with a database other than the
top-level of your database.  You can set QMTEST_DB_PATH to the database
location ("$HOME" in your example) so that you run "qmtest" from
anywhere -- but you should always run "tests.test_suite" that way -- it
doesn't generally work to go into "tests" and then ry to run
"test_suite".

(There's something called a "MountDatabase" for combining multiple test
databases into something bigger, and it does spport the kind of thing
you're doing -- but I don't think that's what you want here.)
