【问题描述】：

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

Creating test database for alias 'default'...

使用 django 1.4 和 selenium python-bindings 2.28.0 和 Firefox WebDriver 使用 LiveServerTestCase 运行测试。有人知道如何解决吗？

【问题讨论】：

Broken pipe error selenium webdriver, when there is a gap between commands?的可能重复

【参考方案1】：

确保请求页面的浏览器正在等待响应。

如果我没记错的话，有 selenium_client.implicitly_wait(sec) 和 selenium_client.set_page_load_timeout(sec) 命令，请确保您正在使用它。

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了连接。

【讨论】：

谢谢！虽然 selenium_client.waitForPageToLoad(ms) 在那个版本/python-bindings 中不存在，但诀窍是设置隐式超时：selenium_client.implicitly_wait(sec) 和 selenium_client.set_page_load_timeout(sec)

但事实并非如此。 selenium_client.waitForPageToLoad(ms) 不存在。
