typo:
s/activitie/activity/

plus I'm not sure if we can be sure that all the activities are the same
in this call (if it's just a multiplication of one array)? On other
places (like 'libvirt-test-api.py') we check for all members in the array.

second typo or copy paste error :)
s/activitie/activity/

I don't quite understand what are you trying to achieve here. The order
of keys and values in python dict cannot be guaranteed if I'm not wrong.
And even if yes, that would mean you are checking just for the first
testcase, I guess. Or maybe I just don't get this right.
