Question

我在从Django运行SeleniumRC时遇到了麻烦。我可以在Python shell中运行Selenium docs和python selenium client docs提供的示例代码，而不运行Django（所以没有manage.py），但是当我实际尝试从django运行Selenium时TestCase或者从Django shell，我得到一个超时错误。这是我正在尝试运行的代码：


from selenium import selenium
from django.test import TestCase

class TestSelenium(TestCase):
    def setUp(self):
        self.verificationErrors = []
        self.selenium = selenium("localhost", 4444, "*firefox", "http://127.0.0.1:8000/")
        self.selenium.start()

    def test_foo(self):
        sel = self.selenium
        sel.open("/")

使用manage.py test registration.TestSelenium运行会产生以下错误：


======================================================================
ERROR: test_testformmaintainsdata (registration.tests.TestSelenium)

    result = self.do_command(verb, args)

    response.begin()

    version, status, reason = self._read_status()

    line = self.fp.readline()
  File "/usr/lib/python2.6/socket.py", line 427, in readline
    data = recv(1)
timeout: timed out

Ran 1 test in 12.475s

奇怪的是，即使抛出错误，并且Python停止，SeleniumRC服务器确实启动了Firefox，但是自从Django停止后我无法运行更多的Selenium命令。这是SeleniumServer的输出：

有人有什么想法吗？

Answer 1

如果其他人遇到此问题，我可以通过在setUp方法中增加套接字超时来解决它。

Answer 2

这将使用浮点秒中的超时值来实现：

import socket

from selenium import selenium
from django.test import TestCase

class TestSelenium(TestCase):
    def setUp(self):
        socket.settimeout(30)
        # ...
        self.selenium.start()

请参阅python stdlib docs
