Selenium無法打開Firefox 48.0.1

我開始學習如何在Django中創建Web應用程序時成爲更好的測試驅動開發人員。我正在嘗試使用Selenium來打開瀏覽器，但是我收到了錯誤消息。Selenium無法打開Firefox 48.0.1

selenium.common.exceptions.WebDriverException: Message: Can't load the profile. Profile Dir: /var/folders/xn/bvyw0fm97j1_flsyggj0xn9r0000gp/T/tmptoxt890d If you specified a log_file in the FirefoxBinary constructor, check it for details.

我讀過「安裝FF擴展」禁用附加組件兼容性檢查「跳過這一切都很好。」 selenium.common.exceptions.WebDriverException: Message: Can't load the profile。我做到了這一點，但它仍然無法正常工作。我在Selenium版本2.53.6中使用了Python2.7和Python3.5。

Python的文件

from selenium import webdriver 
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities 
import unittest 

caps = DesiredCapabilities.FIREFOX 
caps["marionette"] = True 

class NewVisitorTest(unittest.TestCase): 

    def setUp(self): 
     self.browser = webdriver.Firefox(capabilities=caps) 

    def tearDown(self): 
     self.browser.quit() 

    def test_can_start_a_list_and_retrieve_it_later(self): 
     self.browser.get('http://localhost:8000') 

     self.assertIn('To-Do', self.browser.title) 

if __name__ == '__main__': 
    unittest.main(warnings='ignore')

該錯誤是因爲你使用FF 48.對於FF> = 47 FirefoxDriver停止工作。您必須使用新的MarionetteDriver

設置這樣的：

from selenium import webdriver 
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities 

caps = DesiredCapabilities.FIREFOX 
caps["marionette"] = True 

browser = webdriver.Firefox(capabilities=caps) 
browser.get('http://localhost:8000') 

assert 'Django' in browser.title

真棒，它的工作。謝謝Yacdaniel Hurtado！現在我可以繼續學習。 – JBT

我有這個工作，我不知道晚上發生了什麼，但現在我得到這個問題。 NotADirectoryError：[Errno 20]不是目錄。我是否必須將我的計算機上的Firefox可執行文件的路徑傳遞給Firefox以及功能？ – JBT

是的，你可以添加它：'caps [「binary」] =「/ usr/bin/firefox」但它看起來像其他類型的問題，你改變了你的代碼或什麼？ –
