How to set self.maxDiff in nose to get full diff output?
You set maxDiff to None.
But you will have to actually use a unittest.TestCase for your tests for that to work. This should work.
class MyTest(unittest.TestCase): maxDiff = None def test_diff(self): <your test here>
I had the same problem in Python 3 (from reading the other answers here) and using im_class did not work. The snippet below works in Python 3 (cf. How to find instance of a bound method in Python?):
assert_equal.__self__.maxDiff = NoneAs @Louis commented, the convenience functions are bound methods on a Dummy instance. They all seem to be on the same instance, so changing this for e.g. assert_equal will change it for assert_dict_equal et cetera. From the Python docs, __self__ is available from Python 2.6 and forward.
