demo3.py 将熊猫作为pd导入 从selenium.webdriver.support.ui导入选择 导入演示1 从demo2导入登录页面 从selenium.webdriver.common.action_chains导入ActionChains

导入demo2

import unittest

class configuration(demo1.Login):
    def test_demo(self):
        driver=self.driver

        test=loginpage().test_login()

        conf= driver.find_element_by_link_text('Configuration')
        hover=ActionChains(self.driver).move_to_element(conf)
        hover.perform()

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

**追踪（最近通话）：   在test_demo中，文件“ /root/eclipse-workspace/NMS/src/demo/demo3.py”，第23行     test = loginpage（）。test_login（）   在test_login中，文件“ /root/eclipse-workspace/NMS/src/demo/demo2.py”，第21行     driver = self.driver

AttributeError：“登录页面”对象没有属性“驱动程序”

错误：test_login（demo2.loginpage）
