[TIP] Can coverage.py be used to collect coverage data for Functional or integration tests?

Only if Python provides a way to do that - which to my knowledge, it
does not.

(You *could* probably attach via gdb and use that to trace what Python
code is being executed - but it's going to be painful and horribly
slow :P)

coverage.py doesn't care what test framework you're using. Think of it
as a wrapper around a Python process - you can also just do:

   coverage run python foo.py

without any test framework involved.

So either just run your entire test framework under coverage, or do
something like what pytest-cov does:
https://github.com/pytest-dev/pytest-cov/tree/master/src/pytest_cov

(alternatively, stop using your own test framework and extend
something more common instead :P)
