python - 带有 selenium 的单元测试在 python 中完美无缺，但在 django manage.py 测试中出现导入错误

Question

我有这个文件，是从 Selenium IDE 生成的

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
import unittest, time, re

class Tcase(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "http://localhost:9999/"
        self.verificationErrors = []

    def test_tcase(self):
        driver = self.driver
        driver.get(self.base_url)
        # other things...

    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException, e: return False
        return True

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

if __name__ == "__main__":
    unittest.main()

我正在开发一个 Django 项目 (1.4) 和 python 2.6，我想用 Selenium 对其进行测试。

如果我直接从 python 运行这个文件，它可以正常工作。

如果我运行这个做

python manage.py test myapp

导入错误

C:\web\opineo> python .\manage.py test core

    from selenium import webdriver
ImportError: cannot import name webdriver

怎么了？ Selenium 文件在那里!在 Python 2.6 的站点包中

编辑:

这有效，正如预期的那样，它打开了 Firefox

PS C:\web\opineo> python.exe .\manage.py shell
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32
>>> from selenium import webdriver
>>> driver = webdriver.Firefox()

Answer 1

最后我发现了问题:从测试中调用的文件名为 selenium.py，所以它覆盖了库；一个非常新手的错误。

这就是它在 selenium 中找不到 webdriver 的原因!
