This SO answer helped me solve it.
In the end, this is the updated working test code:
def test_create(self):
(abs_dir_path, filename) = os.path.split(self.image)
with open(self.image) as infile:
_file = SimpleUploadedFile(filename, infile.read())
attachment = Attachment.objects.create(
model_id=self.model.id,
file=_file
)
self.assertIsInstance(attachment, Attachment)
self.assertEqual(
attachment.filename,
self.image.split('/')[-1] # test-mountains.jpg
)
