Nosetest和unittest.expectedFailures [英] Nosetest and unittest.expectedFailures

问题描述

我目前正在使用Selenium，Python和鼻子测试来测试我的网站.对于成功的测试，一切正常，我在失败测试中遇到了问题(我从未使用Python/Selenium/Nosetest进行过测试……). 对于以下测试:

I am currently testing my website with Selenium, Python and nosetests. Everything works fine for success tests, I got a problem on failure tests (I have never test with Python / Selenium / Nosetest so ...). For the following test :

 @unittest.expectedFailure
    def test_connection_failure(self):

        # Fill the username with the login only
        self.driver.find_element_by_id('form_identifiant').send_keys(test_login)

        # Send the form
        self.driver.find_element_by_id('form_submit').click()

        # Check the landing URL
        page_url = self.driver.current_url
        self.assertEqual(page_url, page_home)

我正在测试一个非常简单的案例:当您仅输入登录名时，您将无法连接到该网站.因此，当我比较当前页面的URL和登录名/密码对正确的页面时，除了失败之外，我没有做其他事情.

I am testing a very simple case : when you enter only a login, you can't connect to the website. So I do except a failure when I compare my current page URL and the page where I should be if the login / password couple were correct.

我从鼻子测试提示中收到以下消息:

I got the following message from nosetests prompt :

[root@localhost AppGestion]# nosetests ConnectionTests.py
/usr/lib64/python2.7/unittest/case.py:380: RuntimeWarning: TestResult has no addExpectedFailure method, reporting as passes
  RuntimeWarning)

我只是不明白这个错误.我在网上找到了"addExpectedFailure"方法，但没有找到如何使用它，放在何处……我想这样做是因为实际上鼻子测试只是跳过了该测试.

I just don't understand this error. I found the "addExpectedFailure" method on the net but didn't found how to use it, where to put it ... I would like to because the test is just skipped by nosetest actually.

有任何线索吗?

推荐答案

使用nose处理预期异常的装饰器是@raises(...):

The decorator with nose to handle an expected exception is @raises(...):

http://nose.readthedocs.io/en/latest/testing_tools.html

但是在您的情况下，您可以简单地使用assertNotEqual而不使用装饰器:

But in your case, you could simply use assertNotEqual without the decorator:

def test_connection_failure(self):

    # Fill the username with the login only
    self.driver.find_element_by_id('form_identifiant').send_keys(test_login)

    # Send the form
    self.driver.find_element_by_id('form_submit').click()

    # Check the landing URL
    page_url = self.driver.current_url
    self.assertNotEqual(page_url, page_home)
