send_keys 在 django 测试中不起作用

Question

我想要功能测试

功能测试流程是

1. 创建用户
2. 使用创建的用户登录网站
3. 单击名为booksale 的按钮

在myproject/functional_test/test_booksale.py

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from django.test import LiveServerTestCase

from users.models import User


class OurClientLogInTest(LiveServerTestCase):

    def setUp(self):
        self.browser = webdriver.Firefox()
        ## create 1 user id
        User.objects.create_user(username='MyTestID', password='123', nickname='NICKNAMETEST', phone='01011111111')


    def tearDown(self):
        self.browser.quit()

    def test_our_client_can_log_in_this_website(self):

        # url connect
        self.browser.get(self.live_server_url)

        # web page header title has 'Korea book'
        self.assertIn('Korea book', self.browser.title)

        # click log_in button in main page
        log_in = self.browser.find_element_by_id('log_in')
        log_in.send_keys(Keys.ENTER)
        self.assertIn('로그인', self.browser.title)

        # insert username, password
        # click enter
        username_box = self.browser.find_element_by_name('username')
        password_box = self.browser.find_element_by_name('password')

        username_box.send_keys('MyTestID')
        password_box.send_keys('123')

        self.browser.find_element_by_id('button').click()

        ##redirect main page
        self.assertIn('Korea book', self.browser.title)

        ## click a button named book_sale
        book_sale = self.browser.find_element_by_id('book_sale')
        book_sale.send_keys(Keys.ENTER)

        from IPython import embed; embed()

我指挥python manage.py functional_test

它显示错误

TypeError: join() argument must be str or bytes, not 'NoneType'

当我删除代码时

book_sale.send_keys(Keys.ENTER)

测试非常清楚地通过了

我不明白为什么 book_sale 按钮不发送 ENTER KEY..

请帮帮我

如果book_sale元素是按钮，你应该尝试使用.click()而不是send_keys()：-

book_sale.click()
