在之前介绍的测试框架中，发现测试结果中显示的都是测试用例的函数名，并没有将注释显示出来
这很不符合国人使用阿，没办法，自己动手来改改吧
首先，testtools是继承unittest的一个工具，所以应该存在unittest TestCase的相关函数
看看testtools.testcase原码吧，发现，不显示注释的奥秘在这里
class TestCase(unittest.TestCase): """Extensions to the basic TestCase. :ivar exception_handlers: Exceptions to catch from setUp, runTest and tearDown. This list is able to be modified at any time and consists of (exception_class, handler(case, result, exception_value)) pairs. :ivar force_failure: Force testtools.RunTest to fail the test after the test has completed. :cvar run_tests_with: A factory to make the ``RunTest`` to run tests with. Defaults to ``RunTest``. The factory is expected to take a test case and an optional list of exception handlers. """............def shortDescription(self): return self.id()
原来这里没显示注释，那来改改吧，直接上代码
def __init__(self, *args, **kwargs): """Construct a TestCase. :param testMethod: The name of the method to run. :keyword runTest: Optional class to use to execute the test. If not supplied ``RunTest`` is used. The instance to be used is created when run() is invoked, so will be fresh each time. Overrides ``TestCase.run_tests_with`` if given. """ runTest = kwargs.pop('runTest', None) super(TestCase, self).__init__(*args, **kwargs) self._reset() test_method = self._get_test_method() if runTest is None: runTest = getattr( test_method, '_run_test_with', self.run_tests_with) self.__RunTest = runTest self._testMethodDoc = test_method.__doc__ 这里，加入最后一行
self._testMethodDoc = test_method.__doc__
def shortDescription(self): #return self.id() doc = self._testMethodDoc return doc and doc.split("\n")[0].strip() or None 这里再改成这样。
再次运行，结果如下：
======================================================================FAIL: i dont konw----------------------------------------------------------------------_StringException: Traceback (most recent call last): File "test_case\testtools_learn.py", line 34, in test_case_2 assert 2 == 3AssertionError----------------------------------------------------------------------
很好，显示为用例的注释名了。
