You may need to convert the file into uploaded file format before posting to the url,

from django.core.files.uploadedfile import SimpleUploadedFile
from django.core.files import File

class HouseImageTest(APITestCase):

    def setUp(self):
        self.client = APIClient()
        self.user = mommy.make(User, username='Pan')
        self.house = mommy.make(House, location="100.00, 100.00")
        settings.MEDIA_ROOT = tempfile.mkdtemp()

    def test_post_image(self):

        image = Image.new('RGB', (100, 100))    
        tmp_file = tempfile.NamedTemporaryFile(suffix='.jpg')
        image.save(tmp_file)

        file = File(tmp_file)
        uploaded_file = SimpleUploadedFile('new_image.jpg', file.read(), content_type='multipart/form-data')

        data = {
            'image': uploaded_file,
            'houses': self.house.id,
        }

        self.client.force_authenticate(user=self.user)
        response = self.client.post(reverse('api:house_images-list'), data, format='multipart')
        response.render()

        self.assertEqual(status.HTTP_201_CREATED, response.status_code)
