Python 3.3：使用nose.tools.assert_equals时出现DeprecationWarning

我正在使用nosetest工具来断言pythonunittest https://docs.python.org/3.3/library/unittest.html:

...
from nose.tools import assert_equals, assert_almost_equal

class TestPolycircles(unittest.TestCase):

    def setUp(self):
        self.latitude = 32.074322
        self.longitude = 34.792081
        self.radius_meters = 100
        self.number_of_vertices = 36
        self.vertices = polycircles.circle(latitude=self.latitude,
                                           longitude=self.longitude,
                                           radius=self.radius_meters,
                                           number_of_vertices=self.number_of_vertices)

    def test_number_of_vertices(self):
        """Asserts that the number of vertices in the approximation polygon
        matches the input."""
        assert_equals(len(self.vertices), self.number_of_vertices)

    ...

当我跑步时python setup.py test，我收到弃用警告：

...
Asserts that the number of vertices in the approximation polygon ...
/Users/adamatan/personal/polycircles/polycircles/test/test_polycircles.py:22:    
DeprecationWarning: Please use assertEqual instead.
  assert_equals(len(self.vertices), self.number_of_vertices)
ok
...

我找不到任何assertEqual在鼻子工具中。这个警告来自哪里，我该如何解决它？

The nose.tools assert_*函数只是自动创建的 PEP8aliases为了TestCase方法，所以assert_equals是相同的TestCase.assertEquals().

然而，后者只是曾经alias for TestCase.assertEqual() (note: 没有尾随s）。该警告旨在告诉您，而不是TestCase.assertEquals()你需要使用TestCase.assertEqual() as the 别名已被弃用 http://bugs.python.org/issue9424.

For nose.tools这转化为使用assert_equal（没有尾随s):

from nose.tools import assert_equal, assert_almost_equal

def test_number_of_vertices(self):
    """Asserts that the number of vertices in the approximation polygon
    matches the input."""
    assert_equal(len(self.vertices), self.number_of_vertices)

你用过吗assert_almost_equals（带有尾随s），你会看到类似的警告来使用assertAlmostEqual，还有。
