TestCase can't define an empty list of fixtures

This could be useful if you have a TestCase base class that define some very basic fixtures that are used across all your tests but then, there is a few particular tests that do not want such fixtures.
Let's say you have something like:
class BaseTestCase(TestCase): fixtures = ['basic_data.json'] class NoFixturesTestCase(BaseTestCase): fixtures = 
If you do this you will get this error:
Traceback (most recent call last): File "/home/lgs/proyectos/personal/django/django/test/testcases.py", line 173, in __call__ self._pre_setup() File "/home/lgs/proyectos/personal/django/django/test/testcases.py", line 716, in _pre_setup self._fixture_setup() File "/home/lgs/proyectos/personal/django/django/test/testcases.py", line 848, in _fixture_setup 'skip_validation': True, File "/home/lgs/proyectos/personal/django/django/core/management/__init__.py", line 159, in call_command return klass.execute(*args, **defaults) File "/home/lgs/proyectos/personal/django/django/core/management/base.py", line 289, in execute output = self.handle(*args, **options) File "/home/lgs/proyectos/personal/django/django/core/management/commands/loaddata.py", line 49, in handle "No database fixture specified. Please provide the path " CommandError: No database fixture specified. Please provide the path of at least one fixture in the command line.
You can use this hack as a workaround:
class NoFixturesTestCase(BaseTestCase): fixtures = ['non-existing-file.json']
And now you will get a warning instead of an error.
I'll create a Github branch with a test showing this behaviour and a fix for it.
