with_data misguidely prepends the fixture to *args which breaks unittest.TestCase instance usage.

I believe the following test should pass :-

import fixture
import unittest

class TestFixt (fixture.loadable.LoadableFixture):
    '''Create an empty fixture class which doesn't apply anything'''
    def attach_storage_medium(self,ds): pass
    def rollback(self,): pass
    def commit(self,): pass 

dbfixture = TestFixt()

fixture_tables = []

class SillyTests(unittest.TestCase):

    @dbfixture.with_data(*fixture_tables)
    def test_something_inane(self,fixt =None):
        self.assertNotEqual(fixt,None,"Fixture not applied")



if __name__ == "__main__":
    unittest.main()

However instead of passing in raises an exception AttributeError: <SuperSet at 0x1389690 with keys []> has no attribute 'assertNotEqual' this is due to the fixture being prepending to args (rather than the more usual append) and taking the of the self parameter.

I'd suggest changing the with_data to append , but that risks breaking existing users, so I suggets one of two possibilities.

1. A new decorator which is identical to with_data but appends, rather than prepends the fixture,
2. Modifying with_data to insert the fixture after the first argument if the first argument exists and and is an instance of unittest.Testcase .

I think overall I prefer the first but I've got some PoC code for the second.

Did you ever work around this? I am dealing with the same issue right now.

there is a fix in my fork of this, at rgammans@43aae7b

[hello-josh]

This library is so unmaintained that someone should just fork and fix it.

@TRII that would be our (the "maintainers") preference. We took on the library as it was unmaintained and we needed the Django functionality to be updated. We keep the parts of the library up-to-date with Django's releases as best we can, but we don't have time or knowledge to keep any of the other ORMs supported. Ideally this library could be split into a core and several plugins but this would require a complete re-write with some serious software design considerations.
