[PYTHON] Yield in a class that inherits unittest.TestCase didn't work with nose (depending on the version of nose?)

Experiment

`test_sample.py`


# coding: utf-8
from unittest import TestCase
from nose.tools import eq_


class SampleTest(TestCase):
    def setUp(self):
        pass

    def tearDown(self):
        pass

    def test_sample(self):
        """
Test sample
        """
        for i in xrange(3):
            yield eq_, True, False

Even so

$ nosetests -s -v test_sample.py
Test sample... ok

----------------------------------------------------------------------
Ran 1 tests in 0.001s

It didn't work as expected.

Corrected as below,

`test_sample.py`


# coding: utf-8
from nose.tools import eq_


def test_sample():
    """
Test sample
    """
    for i in xrange(3):
        yield eq_, True, False

Then

$ nosetests -s -v test_sample.py
Test sample... FAIL
Test sample... FAIL
Test sample... FAIL

It worked as expected.

Goodbye, nose. I'm going to go to pytest ... artigatougozaimashita.
