我无法在 python django 中使用 selenium webdriver 选择选项

Question

我正在尝试选择一个下拉选项，但每当我运行它时，它都会引发错误。我是 Selenium 的新手。因此，任何建议都会有所帮助。 这是我的 HTML 代码

<select name="department" required="" id="id_department">
    <option value="" selected="">---------</option>
    <option value="SubAssembly">SubAssembly</option>
    <option value="BoardTest">BoardTest</option>
    <option value="PCBoards">PCBoards</option>
    <option value="TechAssembly">TechAssembly</option>
    <option value="Testing">Testing</option>
    <option value="Welding">Welding</option>
    <option value="SM">SM</option>
    <option value="Mach">Mach</option>
</select>

这是我的 Selenium 代码。

from selenium import webdriver
from accounts.models import RegisterForm
from django.contrib.staticfiles.testing import StaticLiveServerTestCase
from django.urls import reverse
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.select import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as E
from selenium.webdriver.support.ui import Select
import time
import pytest

class TestProjectRegisterPage(StaticLiveServerTestCase):

    def setUp(self):
        self.browser = webdriver.Chrome('functional_test/chromedriver.exe')
    
    def tearDown(self):
        self.browser.close()
    
    def test_no_project_alert_is_displayed(self):
        self.browser.get(self.live_server_url)
        time.sleep(5)
        self.browser.find_element_by_link_text('REGISTER').click()
        time.sleep(5)
        username = self.browser.find_element("id_username")
        username.send_keys('aayush')
        email = self.browser.find_element("id_email")
        email.send_keys('aayush@gmail.com')
        department = Select(self.find_element("id_department")).select_by_visible_text('Testing')
        time.sleep(10)

我在这里缺少什么？谢谢。我正在使用 chrome 网络驱动程序

Answer 1

from selenium.webdriver.support.select import Select

department = Select(self.find_element_by_id("id_department"))
department.select_by_visible_text('Testing')

但你使用：Select(self.find_element("id_department"))

另外，在设置方法中至少添加driver.implicitly_wait(20)。尝试一一删除time.sleep()。

小更新：

self.browser.find_element_by_link_text('REGISTER').click(),

username = self.browser.find_element_by_id("id_username"),

email = self.browser.find_element_by_id("id_email"),

department = Select(self.find_element_by_id("id_department"))

适用于所有定位器都是 ID 或链接文本的情况。
