Python noestest如何模仿MySQLdb

Question

我试图从我的项目中模仿MySQLdb lib，但我真的不知道如何做到：

这是我的测试代码：

import unittest
from mock import MagicMock
from core.distrib.main.CentralDistDraw import CentralDistDraw
from connector.mysql  import MySQL

class CentralDistDraw(unittest.TestCase):
    def test_hello(self):
        draw = CentralDistDraw()
        msql = MySQL()
        msql.getConnection = MagicMock()

这是我的课：

^{pr2}$

引发的错误：

有人知道测试第三方库的正确方法吗？在
