Question

我使用命令＃34执行以下代码：nosetests --with-html test_rest_api.py＆＃34;

class Test_rest_api(unittest.TestCase):

    def test_create_task_group(self):
        data = {"name":"group2"}
        response = ib_api.rest_request('POST', object_type="create_Test")
        msg = json.loads(response.read())
        self.assertTrue(response.status >= 200 and response.status < 300,msg)

if __name__ == '__main__':
    unittest.main(verbosity=2)

如果案例失败，我会得到变量＆＃34; msg＆＃34;中的字符串，但如果案件通过，我就不会收到消息

尝试如下解决方案，

self.assertTrue(response.status == 200 , msg)
print msg

这样可行，但问题是如果案例失败，则在html报告中出现2次消息

请建议处理上述案件的任何好方案

我最终定制了unittest的断言函数，以便在我的日志记录中获取PASS消息。

像这样：

class TestBase(unittest.TestCase):
    def _assert_logs(self, expr, msg=None):                                                         
        """                                                                                         
        Helper function: Auto-logs PASS/FAIL for all overriden asserts                                 

        Keyword arguments:                                                                             
            expr -- Conditional expression appearing in an assert, ex. "x is None"                     
            msg -- General message to log (default = None)                                             
        """                                                                                         
        if expr:                                                                                       
            self.log.debug("PASS {0}".format(msg))                                                     
        else:                                                                                          
            self.log.error("FAIL {0}".format(msg)) 

    def assertIn(self, member, container, msg=None, expected=None,                                     
                 actual=None):                                                                         
        """

        Arguments:

            second -- second variable of conditional being evaluated                                   

        Keyword arguments:                                                                             
            msg -- msg that identifies the test assertion

        msg = self._format_message(msg, expected, actual)                                              
        self._assert_logs(member in container, msg)                                                    
        super(TestBase, self).assertIn(member, container, msg)

然后让您的测试用例继承自TestBase而不是unittest.TestCase。希望它有所帮助！

python unittest也为所有传递的案例添加消息并在nose html报告中打印
