[SciPy-dev] Making numpy test work in scikits

I have to say that the fact that not all test_*.py are parsed for tests
annoys me in Numpy. If you want to test a file something.py, you have to
create a tests/test_something.py, you can't use an other name. And when you
want to test more than just a part of your code - like for the optimizers, I
want to test several modules together -, those tests are not part of the
test suite that Numpy creates.
Thus, I created a file that executes all test_*.py, but it cannot work with

But I thought that this worked (I think I've used it before) :

def test():
  from numpy.testing import NumpyTest
  return NumpyTest().test()

in the __init__.py of a module that must be tested, doesn't it ?
