# Django 1.3 adds 'assertNumQueries'. Here is how to do fuzzy testing 
# with this function, using a clever subclass of int.

class FuzzyInt(int):
    def __new__(cls, lowest, highest):
        obj = super(FuzzyInt, cls).__new__(cls, highest)
        obj.lowest = lowest
        obj.highest = highest
        return obj

        return other >= self.lowest and other <= self.highest

    def __repr__(self):
        return "[%d..%d]" % (self.lowest, self.highest)

    def test_1(self):

        with self.assertNumQueries(FuzzyInt(5,8)):
