Python 2.7和3.4:为什么test_unexpected_error测试会抛出错误而不是失败？

import unittest


class TestLists(unittest.TestCase):

    def test_unexpected_error(self):
        self.assertEqual([0] * 1000 + [1], [1] + [0] * 1000)

    def test_fails_as_expected(self):
        self.assertEqual([0] * 1000 + [1], [0] * 1000 + [0])


if __name__ == '__main__':
    unittest.main()

错误是:

RuntimeError: maximum recursion depth exceeded while calling a Python object

回溯(删节 - 递归错误是一个递归错误是一个递归错误是....)
