(Python 3.5 and Django 1.10)

I am trying to test a Django form that enables a required file upload.

The form is very simple and includes a field that looks like:

    upload_file = forms.FileField()

The corresponding test to try and check the upload:

def test_form_validation_with_file(self):

    fake_file = ContentFile(b'''Some file content''')

    fake_file.name = 'fake.xls'

    suf_file = SimpleUploadedFile('suf.xls', b'''this is text''')

    data = {

        'upload_file': suf_file,

    }

    form = forms.RequestForm(data=data)

    self.assertTrue(form.is_valid())

The form validation fails i.e. it does not seem to recognise that file data has been suppplied.

I have also tried with the  "fake_file" for the data but without success.

Any help or pointers appreciated.

It does not appear that you are binding the file to the form correctly. Django forms use a separate argument to the form class for file content. It is not part of the form 'data'.
