Python模块属性错误

Question

我知道这个话题已多次出现，但我完全陷入困境并需要帮助。请告诉我这里做错了什么以及如何解决它。提前谢谢。

# testcase1.py

import unittest
import sys


class Global:

    b = 0


class Util_Case_ID(unittest.TestCase):

    def setUp(self):
        sys.path.insert(0, 'C:/**/views')
        sys.path.insert(0, 'C:/**/app')
        sys.path.insert(0, 'C:/**/tests')

        from app.views.utility import method_a
        Global.b = len(method_a())

    def test1(self):
        self.assertEqual(Global.b, 11)

    def tearDown(self):
        sys.path.remove('C:/***/app/views')
        sys.path.remove('C:/***/app')
        sys.path.remove('C:/*/tests')

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

AttributeError：module＆＃39; UnitTests＆＃39;没有属性＆＃39; testcase1＆＃39;

Traceback如下：
