我正处于使用 Django 开发网络应用程序的开始阶段。 我在 Vagrant 中使用 headless Selenium 设置。
访问页面工作正常，但在下面的测试中它只是挂起。 我不确定这是否是由于 selenium 和我的 firefox 版本之间的兼容性。
我测试环境的pip3卡住:
coverage==4.0.3
defusedxml==0.4.1
Django==1.9.1
django-allauth==0.24.1
oauthlib==1.0.3
psycopg2==2.6.1
python3-openid==3.0.9
requests==2.9.1
requests-oauthlib==0.6.0
selenium==2.49.0
wheel==0.24.0
xvfbwrapper==0.2.7
firefox -v
火狐浏览器 43.0.4
我将从我编写的类开始测试 allauth(Google 登录)而不是挂起的特定函数。

self.vdisplay.start()
self.browser = webdriver.Firefox()
self.browser.maximize_window()
self.browser.implicitly_wait(3000)
self.browser.wait = WebDriverWait(self.browser, 5)

self.browser.quit()
self.vdisplay.stop()
def get_element_by_id(self, element_id):
return self.browser.wait.until(EC.presence_of_element_located(
(By.ID, element_id)))
def get_button_by_id(self, element_id):
return self.browser.wait.until(EC.element_to_be_clickable(
(By.ID, element_id)))
def get_full_url(self, namespace):
return self.live_server_url + reverse(namespace)
以下测试挂起。
def test_google_login(self):
self.browser.get(self.get_full_url("home"))
google_login = self.get_element_by_id("google_login")
with self.assertRaises(TimeoutException):
self.get_element_by_id("logout")
self.assertEqual(
google_login.get_attribute("href"),
self.live_server_url + "/accounts/google/login")
google_login.click()
with self.assertRaises(TimeoutException):
self.get_element_by_id("google_login")
google_logout = self.get_element_by_id("logout")
google_logout.click()
google_login = self.get_element_by_id("google_login")
奇怪的是，如果我把所有东西都拿出来，只运行它通过的前两个句子。 但是，当我插入 with 语句时它挂起!
如果我运行前两个句子并 assertEqual href 属性(因此没有 with 语句和其他所有内容)它通过。当我还添加 google_login.click 时，它再次挂起。
当我按 CTRL-C 测试时，我得到以下回溯:

希望有人能帮我解决这个问题。 提前致谢!!
请您参考如下方法:
我也遇到了 firefox webdriver 的问题。尝试将您的 Firefox 降级到版本 36。这是对我有用的最后一个版本。
