And also requires each test to be separately decorated. Grouping tests
with the same setUp and tearDown into common classes with unittest is
useful.
I'm intrigued about using decorators to mark tests and the setUp and
tearDown - of course this is configuration over convention and actually
marginally more work. I would still want test classes to inherit from
TestCase to inherit the functionality.
It is possible that the xUnit frameworks for statically typed languages
use decorators for tests rather than naming conventions because
introspection is so much harder in these languages. Pure speculation on
my part of course.
Any other useful decorators provided by the xUnit frameworks?
