hardcoding 2.7 is OK

again, testing sources, even without extensions is not something we
should do. If testing if all files are installed doesn't convince you,
how about 2to3 changes not applied while testing Python 3.X?

... and you will end up in debian/rules that is 5 times bigger than
before and once pytest's interface changes, your package FTBFS - that's
OK if you have time to update all your packages, but if you, like me,
are lazy, then you can use "not very helpful for running tests" pybuild
that does all above and more for you.
