如何对单元测试单元进行测试

我有一个unittest.TestCase子级,它定义了几个特定于域的断言检查.
我想运行一些单元测试来对该功能进行单元测试,以控制一切在以后的更新中正常工作.

class MyBaseTestCase(unittest.TestCase):
    def setUp(self):
        ...
    def tearDown(self):
        ...
    def run(self, result):
        ...
    def assertSpec(self, condition, message):
        ...

我想在其他单元测试中实例化MyBaseTestCase,如下所示：

class TestBase(unittest.TestCase):
    def test_assertSpec(self):
        self.testclass = MyBaseTestCase()
        self.assertRaises(AssertionError, self.testclass.assertSpec, False)

执行此操作时,我遇到多个不同的错误,所以我的问题是对单元测试自定义unittest函数进行单元测试的常见做法是什么？

如果有帮助：

$jython
>>> import sys
>>> sys.version
'2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06) \n[Java HotSpot(TM) Server VM (Sun Microsystems Inc.)]'

解决方法:

不知道是否有任何Jython特定的东西可以打破这个,但是我会做这样的事情：

import StringIO
import unittest


# The TestCase subclass to test    
class MyBaseTestCase(unittest.TestCase):
    def assertSpec(self, thing):
        assert thing == 123


# The testcase for MyBaseTestCase
class TestMyTest(unittest.TestCase):
    def test_assetSpec(self):
        """Ensure assertSpec works
        """

        class _TestSpec(MyBaseTestCase):
            def test_failure_case(self):
                 self.assertSpec(121)
            def test_success_case(self):
                 self.assertSpec(123)

        # Load tests from _TestSpec
        loader = unittest.TestLoader()
        suite = loader.loadTestsFromTestCase(_TestSpec)

        # Create runner, and run _TestSpec
        io = StringIO.StringIO()
        runner = unittest.TextTestRunner(stream = io)
        results = runner.run(suite)

        # Should be one failed test, and one passed test
        self.assertEquals(results.testsRun, 2)
        self.assertEquals(len(results.failures), 1)

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