The next 'big' change to unittest will (may?) be the introduction of
class and module level setUp and tearDown. This was discussed on
Python-ideas and Guido supported them. They can be useful but are also
very easy to abuse (too much shared state, monolithic test classes and
modules). Several authors of other Python testing frameworks spoke up
*against* them, but several *users* of test frameworks spoke up in
favour of them. ;-)
One problem is that it is not obvious what happens with inheritance.
If I have a class-level setUp for class B, and class C inherits from B,
will there be a separate invocation of setUp for C, or not?
(I guess both possibilities have use cases)
Well, what I would expect (others may disagree) is that you only have
class level setup invoked for classes that have tests (so not for base
classes) and that the base-class setUpClass is only called if invoked by
the subclass.
I haven't thought about *where* the code to do this should go. It
*could* go in TestSuite, but that feels like the wrong place.
