用硒运行django-test时管道出现错误

Question

在使用selenium(没有远程,没有xvfb)运行django测试时,我总是得到以下异常:

Creating test database for alias 'default'...

使用django 1.4和selenium python-bindings 2.28.0与Firefox WebDriver一起使用LiveServerTestCase运行测试.有人有想法,如何解决它？

确保请求页面的浏览器正在等待响应.

如果我没记错,那就是selenium_client.implicitly_wait(sec)和它的selenium_client.set_page_load_timeout(sec)命令,请确保你正在使用它.

如果不是,服务器将尝试写入已损坏的管道,因为浏览器在发送响应之前关闭连接.
