I think it's a great idea :-) The current design of Tracker makes it tricky to write tests. I would like to make it easier to use the Tracker store and the mining and extraction code within a single process, but that requires a bit of work. So the current "state of the art" is to set up a separate D-Bus and start instances of all the Tracker daemons attached to that bus. This is done by setting the DBUS_SESSION_BUS_ADDRESS environment variable for each of the daemon processes. Additionally you set XDG_CACHE_HOME and XDG_DATA_HOME so that tracker-store places its database elsewhere instead of overwriting the user's real tracker-store files that are in ~/.cache/tracker and ~/.local/share/tracker. Finally to get a different configuration you can use the DCONF_PROFILE environment variable. There are two implementations of this in tracker.git :-) One you've spotted in https://github.com/GNOME/tracker/tree/master/tests/functional-tests/. The D-Bus session bus is set up in test-runner.sh and then in common/utils/system.py there's the TrackerSystemAbstraction class which is a helper to set up the rest of the test environment. The other implementation is the https://github.com/GNOME/tracker/blob/master/utils/sandbox/tracker-sandbox.py script which does more or less the same thing, but is a commandline tool aimed mainly at helping to debug the Tracker daemons. Neither of these are perfect, improvements to either is welcome. Ideally we'd merge the two implementations and fully document on the wiki for folk who want to reuse them.
