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，并且在两个功能性Web测试用例中注意到了该错误。所有的测试用例都在最后通过，但是我在控制台中得到了:

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'...

这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)

它运行完毕，但转储了上述异常。这个想法是测试一个简单的注册页面。单击提交按钮后，页面会重新显示并提示用户填写其他表单字段。正如预期的那样，一切似乎都可以正常工作，但是为什么会出现错误？我想念什么吗？

用127.0.0.1替换localhost对我不起作用，而添加sleep只会减慢测试速度。在退出浏览器之前，我可以通过调用refresh来消除错误:

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

在我的情况下，导致问题的是 <link>和 <script>标记中的静态文件加载。但是当我退出之前添加 refresh时，它消失了。
