[Tracker] Tests with tracker

[Éloi Rivard <eloi rivard gmail com>]

Hi.

I would like to write some tests in an existing program that uses tracker. I would like to not run tests on the system daemon. I saw that there are some interesting things here https://github.com/GNOME/tracker/tree/master/tests/functional-tests

I did not find clear documentation about this topic. I just come here to check with you if I did not missed some documentation, and take some advices. So, what do you think about tests?
