Use doctest or dutest [1]_ loaders and specify an HTML-aware output
checker (e.g. lxml.doctestcompare.LHTMLOutputChecker [3]_, [4]_ ...)

Perhaps there are different options out there ... Pls feel free to
send us (the list ;) feedback about your research ...

;) ... If using unittest-like TCs ... You could easily put together
your test suites using dutest.MultiTestLoader to load them at once ...
and there is also another loader available to load the tests found in
a specified folder and subfolders ... using regex filters too ... ;)

An article [2]_ covers something like this by using dutest module ...
perhaps some minor modifications are required since new versions may
have introduced either enhancements or bug fixes ...
