Python Selenium 2.39 和 Firefox 26

Question

我正在尝试使用 unittest 脚本执行一些 selenium，但出现以下错误

Ran 1 test in 766.686s

FAILED (errors=1)

template.py 中第 70 行的 tearDown() 函数中出现错误，该函数是使用 Selenium-IDE 自动生成的默认单元测试函数

def tearDown(self):
    self.driver.quit()
    self.assertEqual([], self.verificationErrors)

编辑:

这个问题发生在我将 Firefox 更新到 26 时，即使我更新到 selenium 2.39.0 问题也没有消失

我是这样解决问题的

从 here 获取便携版 Firefox (获取与您一起使用的版本，例如我有 Firefox 版本 23)并将其解压缩到特定目录

import os 
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary(os.path.join('Pathto','FirefoxPortable','FirefoxPortable.exe'))
driver = webdriver.Firefox(firefox_binary=binary)

这已经用 selenium 2.37.2 和 2.39.0 测试过

尽情享受吧!
