I'd do it with inline Python. Something like:

>>> from mercurial import hg, ui as uimod
>>>  myui = uimod.ui.load()
>>>  repo = hg.repository(myui, path='.')
>>> 
>>> 1. Test repo.changelog here.

Also, excessive `hg` commands makes tests slow. Unfortunately, doing this in Python is probably a bit of work :/
