如何在Django中测试具有表单的视图？

Question

I am creating an application in Django and I have a view which receives a form from the html code, and searches in the database if there are any instances of a model whit the values specified in the form.

The problem is that I am new in Django and I don't really know how can I test the functionality of the view (ie: if the view's response has a list of values resulting the search of the values of the form in the request).

Here I put the example code of my view:

@login_required
def view(request):

# If it's a HTTP POST, we're interested in processing form data.
if request.method == 'POST':

    form = Form(data=request.POST)

    # If the form is valid
    if (form.is_valid()):

        resulting_of_search = ModelA.objects.filter(Q(att1=request.POST[attr1]) & ...)



    else:
        resulting_of_search = []


# Not a HTTP POST, so we render our form using two ModelForm instances.
# These forms will be blank, ready for user input.
else:
    form = Form()
    resulting_of_search= []



# Render the template depending on the context.
return render(request,
        'url/url.html',
        {'resulting':resulting_of_search} )

Have you tried the Django Testing Tutorial ? Essentially, you just need to send a post to your view and test that the response returns what you'd expect.

For example..

def test_index_view_with_no_questions(self):
    """
    If no questions exist, an appropriate message should be displayed.
    """
    response = self.client.get(reverse('polls:index'))
    self.assertEqual(response.status_code, 200)
    self.assertContains(response, "No polls are available.")
    self.assertQuerysetEqual(response.context['latest_question_list'], [])

Taken from the docs. You'd want to change that last line so that you assert that 'resulting' is in the context. Or check that it contains a specific list of results you're looking for. Like this..

def test_results(self):
    response = self.client.get(reverse('ensaioak_bilatu'))
    self.assertQuerySetEqual(response.context['resulting'], [...whatever you expect resulting to contain...])

From reading your answer, I think you are not asking about unit testing but just checking whether your view actually works . As a start, you can use the code snippet provided on the Django website at the following link: https://docs.djangoproject.com/en/1.8/topics/forms/#the-view .
