问题描述

我正在尝试模拟django.contrib.auth authenticate方法的返回值,该方法在视图的登录方法中调用.

I am trying to mock the return value of the django.contrib.auth authenticate method which is called within the login method of a view.

有view.py代码:

There's the view.py code:

def login(request): 
    if request.method == 'POST': 
            username = get_username(request.POST.get('email')) 
            password = request.POST.get('password') 

            user = authenticate(username=username, password=password) 

            if user: 
                    if user.is_active: 
                            if not request.POST.get('remember_me', None): 
                                    request.session.set_expiry(0) 
                            auth_login(request, user) 
                            return redirect('/') 
                    else: 
                            return redirect('/') # some error page 
            else: 
                    return redirect('/') # error again 
    else: 
            return render(request, 'auth/login.html') 

还有test.py代码:

And the test.py code:

from django.contrib import auth
...
@patch.object(auth, 'authenticate')
def test_login_missing_user(self, mock_auth):
    request = self.request_factory.post('', data={'email': u'[email protected]', 'password': u'PA$$WORD'})
    self.assertIsInstance(login(request), HttpResponse) #this test PASSES

    user = User.objects.create_user('test_user', '[email protected]', 'test_password')

    mock_auth.return_value = True
    login(request)
    self.assertTrue(mock_auth.called)

最后一个断言失败并出现AssertionError:False不为真

The last assertion fails with AssertionError: False is not true

推荐答案

您正在修补错误的东西:您所做的只是更改测试中而不是视图中authenticate所指的内容.您应该修补your_view.auth.authenticate.

You're patching the wrong thing: all you've done is change what authenticate refers to within your test, not in the view. You should patch your_view.auth.authenticate.

在何处修补上查看Mock文档.

See the Mock docs on Where to patch.
