Django和Selenium Web测试错误:[Errno 10054]

Question

我正在使用Selenium Web驱动程序运行一些基本的功能性Web测试,我在两个功能性Web测试用例中注意到了这个错误.测试用例都在最后通过,但我在控制台中得到了这个:

Exception happened during processing of request from ('127.0.0.1', 1169)
    data = self._sock.recv(self._rbufsize)
error: [Errno 10054] An existing connection was forcibly closed by the remote host

Destroying test database for alias 'default'...

以下是其中一个测试用例的示例:

def test_can_join_main_site(self):
    self.browser.get(self.live_server_url)
    self.browser.find_element_by_link_text('Register').click()
    time.sleep(5)
    self.browser.find_element_by_name('submit').click()
    time.sleep(5)

它运行完成但转储上述异常.我们的想法是测试一个简单的注册页面.单击提交按钮后,页面将重新显示并提示用户填写其他表单字段.正如所料,一切似乎都正常,但为什么错误？我错过了什么吗？

Answer 1

替换localhost为127.0.0.1对我来说不起作用,添加sleep只会减慢测试速度.我在退出浏览器之前通过调用refresh来摆脱错误:

from selenium import webdriver
browser = webdriver.Firefox()
# do stuff with browser
browser.refresh()
browser.quit()

在我的情况下,正在加载导致问题的静态文件<link>和<script>标签.但是当我refresh在戒烟之前添加时它就消失了.

Answer 2

使用FireFox，我能够通过充分减慢关机过程来解决此问题：

@classmethod
def tearDownClass(cls):
    time.sleep(3)
    cls.selenium.quit()
    time.sleep(3)
    super(TestClass, cls).tearDownClass()

Answer 3

我通过在 URL 中localhost替换为来解决了该问题：127.0.0.1

    url = self.live_server_url
    url = url.replace('localhost', '127.0.0.1')
    self.driver.get('%s%s' % (url, reverse('whatever')))
