Hi Jouni,
I just installed gs on one of the buildbots -- so at least the .pdf
generation should get tested on one machine. (The one running the py24
and py25 tests.)
As far as the decorator turning one test in into multiple tests out --
it may be possible. Nose does this automatically for tests like:
def check_sum(func):
a = 10; b = 20
assert a+b == func(a,b)
def test_sum():
for func in [np.add, pylab.add]:
yield check_sum, func
This test function is a generator that nose will then generate two test
cases out of. So, perhaps the image_comparison decorator could be
changed to become a generator? I'm not 100% sure it will work, but I
don't see why it won't. If it does work, I think this is a good idea.
