from utils.appender import Appender
import unittest

class AppenderTest(unittest.TestCase):
    def test_GetFileNameByNow(self):
        result=Appender.getFileNameByNow()
        print(result)
        self.assertEqual(result,"2017-12-14 17:00:00.csv")

使用unittest測試時發(fā)生錯誤，請問如何修改:

zjw at monster in ~/project/python/AdFetchExtractor/test (develop●) 
$ python3 -m unittest appender_test.py 
E
