35840	assertFormError shows error when testing form input	KevinS		"Hi all, 

I was encountering some issue using the `self.assertFormError` to test a simple form input. 
Not sure why it keeps giving me the following error; I thought once the form is posted, it should be bound. 

`forms.py`
{{{#!python
class Form_Test(forms.Form):
    name = forms.CharField(max_length=20)
    integer = forms.IntegerField()
    
    def clean_integer(self):
        c = self.cleaned_data['integer']
        if c < 10:
            self.add_error(
                field='integer',
                error='Must be bigger than 10'
            )
        else:
            return c
}}}

`views.py`

{{{#!python
def FormTest(request):
    if request.method == 'POST':
        form = Form_Test(request.POST)
        if form.is_valid():
            print('Hello World')
    else:
        form = Form_Test()
    return render(request, 'basic_form.html', context={'form': form})
}}}

`urls.py ==> path('test-form/', views.FormTest, name='test_form'),`

`test_views.py`

{{{#!python
from django.test import TestCase, 
from django.contrib.auth.models import User
from django.urls import reverse
from ChurchAccount.forms import Form_Test

class AuthViewsTest(TestCase):
    def setUp(self):
        self.form_url = reverse('test_form')

    def test_form_test(self):
        response = self.client.post(self.form_url, data={'name': 'abc','integer': 2})
        self.assertFormError(response, 'form', 'integer', 'Must be bigger than 10')
        self.assertEqual(response.status_code, 200)

    ....
}}}
