我正在使用python版本的selenium进行django的一些测试,但firefox webdriver在尝试启动新会话时抛出URLError异常。我所做的是:
browser = webdriver.Firefox()
更新:然后我做了一些测试,然后我需要关闭它,因为当前测试完成,但是对于下一个我需要一个新的会话,所以我尝试打开一个新的
browser.close()
capabilities = webdriver.DesiredCapabilities()
browser.start_session(capabilities.FIREFOX)
然后它抛出了这个:
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/user/projects/myproject/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 104, in start_session

raise URLError(err)
URLError: <urlopen error [Errno 111] Connection refused>
奇怪的是,同样的步骤与Chrome网络驱动程序完美配合。
有谁知道为什么会造成这种情况? 在此先感谢您的任何帮助

你不应该使用start_session。 在第一行,您将创建本地firefox浏览器的新实例。 start_session是远程webdriver的一种方法。 您所需要的只是:
driver = webdriver.Firefox() #opens new Firefox browser locally
driver.quit() #kills the session
driver = webdriver.Firefox() #opens new Firefox browser locally
由于你在这里重复代码,你应该在测试类中有这样的东西
class Test(unittest.Testcase):
def setUp(self):
self.driver = webdriver.Firefox()
def tearDown(self):
self.driver.quit()
def test_something(self):
#do some magic test here
def test_something_else(self):
#do some other stuff
这样浏览器将在每次测试开始时启动,并在每次测试结束时关闭。
