用HTML 运行 以下代码。出现以上bug 。

coding=utf-8

from selenium import webdriver
import unittest

class Test_ranzhi(unittest.TestCase):

url = 'http://laibaoqin.top/ranzhi/www'
user = 'admin'
password = 12345678


@classmethod
def setUpClass(cls):
    cls.driver = webdriver.Firefox()

@classmethod
def tearDownClass(cls):
    cls.driver.quit()

def test_case1(self):
    pass
    self.driver.maximize_window()
    self.driver.implicitly_wait(30)
    self.driver.get(url)
    text = self.driver.find_element_by_css_selector(".btn").text
    print(text)
    if text != "繁體":  # 选择系统语言
        self.driver.find_element_by_css_selector(".btn").click()
        self.driver.find_element_by_xpath("//*[text()='繁體']").click()

    self.driver.find_element_by_css_selector("#account").send_keys(user)
    self.driver.find_element_by_css_selector("#password").send_keys(password)
    self.driver.find_element_by_xpath("//*[@id='keepLoginon']").click()
    self.driver.find_element_by_css_selector('#submit').click()

    try:
        act_name = self.driver.find_elements_by_css_selector(".nav.navbar-nav>li>a")[0].text
        print(act_name)
        assert act_name == "admin"
    except Exception as e:
        print("验证出错了", e)

    print("11111113")
    self.assertEqual(1 ,2)

python3

[brianlaibaoqin]

self.driver.find_element_by_css_selector("#account").send_keys(user)
self.driver.find_element_by_css_selector("#password").send_keys(password)   有参数化的 报AttributeError: 'NoneType' object has no attribute 'find'  ，请看看 ！

没重现啊，兄弟！你的参数化作用域也不对，下面根本引用不到的，还不如放在class上面

1， 我发现我的原因在哪里了，就是你的bug！

[GoverSky]

1、在teardownClass 中初始化driver 是不会重启浏览器的，一个测试类只执行一次，要每次测试都重启放在setUp和tearDown中初始化和关闭
2、我这不编写注释也没有问题的，不知道你的问什么返回了None，因为本身用的是TestCase的_testMethodDoc，这块再针对改一下~
