Question

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上设置但是我得到了Exception，

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()

以下是完整的异常堆栈：

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 Firefox：47.0

Selenium版本：2.53.6

python版本：2.7.12

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

Answer 1

Selenium正在逐渐使用FirefoxDriver而不是Marionette。几个星期前，当我转向Firefox 47.0并在那时切换到了这个问题时，我遇到了这个问题。
