I don't think it would be seriously easier to write, more maintainable or
easier to understand. There's nothing complicated or obscure in setUp and
tearDown methods (the only annoying thing being PEP8 non-compliance).
As a matter of fact, nose has a "with_setup()" decorator which allows to
avoid writing setUp/tearDown methods. But in my experience it's more
annoying to use because:
- you have to add the decorator explicitly (setUp/tearDown is always
invoked)
- you have to create your own recipient for local state (setUp/tearDown
can simply use the TestCase instance), or use global variables which
is ugly.
