【问题标题】:Selenium is not working with firefox and python webdriver on ububtuSelenium 不能在 ubuntu 上使用 firefox 和 python webdriver
【发布时间】:2016-11-28 19:15:55
【问题描述】:

我正在尝试使用 selenium、firefox 和 python webdrivers 为我的 webapp 编写测试用例,而我的开发环境是在 ubuntu 16.04 LTS 上设置的,但我遇到了异常,

WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

这是我的代码块

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
driver.close()

这是完整的异常堆栈:

Traceback (most recent call last):
  File "LoginLogout.py", line 4, in <module>
    driver = webdriver.Firefox()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 80, in __init__
    self.binary, timeout)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/extension_connection.py", line 52, in __init__
    self.binary.launch_browser(self.profile, timeout=timeout)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser
    self._wait_until_connectable(timeout=timeout)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 99, in _wait_until_connectable
    "The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

我有以下环境设置

Mozilla 火狐:47.0

硒版本:2.53.6

python 版本:2.7.12

操作系统:Linux 4.4.0-31-generic #50-Ubuntu SMP x86_64

【问题讨论】:

  • 你能在 webdriver 之外正常启动 Firefox 吗? chrome或IE驱动会出现这种情况吗?

【解决方案1】:

Selenium 正在放弃使用 FirefoxDriver,转而使用 Marionette。几周前我在迁移到 Firefox 47.0 时遇到了这个问题,当时我切换到了。
