我想为 Django 应用编写一些 Selenium 单元测试。我们已经有很多常规的 python 单元测试。我复制了 example selenium test from the Django docs (这只不过是 selenium 的“hello world”):
from selenium.webdriver.firefox.webdriver import WebDriver
from django.test import LiveServerTestCase
class MySeleniumTestCase(LiveServerTestCase):
@classmethod
def setUpClass(cls):
cls.selenium = WebDriver()
super(MySeleniumTestCase, cls).setUpClass()
@classmethod
def tearDownClass(cls):
cls.selenium.quit()
super(MySeleniumTestCase, cls).tearDownClass()
def test_simple(self):
self.selenium.get("/")
但是，当我在本地或使用 CircleCI 运行它时(在云中测试即服务)，我收到此错误:
======================================================================
ERROR: test_simple (proj.lib.tests.MySeleniumTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):

这是Django 1.5.5，python 2.7，selenium python包2.42.1
有什么问题？如何让 selenium 工作？
请您参考如下方法:
get 方法需要一个完整的 URL。也就是说，URI 包括协议(protocol)和主机名/ip。
self.selenium.get("/")
# becomes
self.selenium.get("http://stackoverflow.com/questions/24011019/")
