class BaseTestCase(unittest2.TestCase):

    def setUp(cls):
        cls.driver = webdriver.Chrome()
        cls.driver.maximize_window()
        # 智能等待3s
        cls.driver.implicitly_wait(3)
        # 登录至主页
        cls.driver.get(r"http://192.168.123.195:50097/otrs/index.pl")
        #cls.driver.get(r"http://127.0.0.1:50099/otrs/index.pl")
        cls.driver.find_element_by_id("User").send_keys("root@localhost")
        cls.driver.find_element_by_id("Password").send_keys("123456")
        cls.driver.find_element_by_id("LoginButton").click()
        time.sleep(3)


    def tearDown(cls):
        # 退出系统
        cls.driver.find_elements_by_css_selector("#LogoutButton")[1].click()
        time.sleep(3)
        cls.driver.quit()
