Looping through Python nosetests

Question

I'm trying to follow this post's recommendation to looping through nosetests but it does not work.

Here is sample code (I need a class implementation):

class NoseTesting(unittest.TestCase):

    def _prepare_incredients(arg):
        """This is private method"""
        logger.info("The args are == {0}".format(arg))

    def test_make_icecream(self,):
        logger.info("Test case starting")
        for arg in ['sugar','cone']:
            yield (self._prepare_incredients,arg)

Answer 1

If you actually read the documentation linked from the previous question:

As in the example, test generators must yield tuples, the first element of which must be a callable and the remaining elements the arguments to be passed to the callable.

Instead, you are calling the method within your "test generator" and yielding the result ( None , in this case). Switch the relevant line to:

yield (self._prepare_incredients, arg)
