I'm try to test my model with ImageField, for this purpose i'm reading .jpg file in binary mode and save in the model. I find a lot of question in StackOverflow, but nothing seems to work for me.
testImagePath = os.path.join(settings.BASE_DIR, 'test_image_folder/test_image.jpg')
"image" : SimpleUploadedFile(name='test_image.jpg', content=open(testImagePath, 'rb').read(), content_type='image/jpeg')
error:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

class Test(TestCase):
testUser = {
"username": "TestUser",
"email": "[email protected]",
"password": "TestUserPassword",
"confirm_password": "TestUserPassword"
}
testAlbum = {
"owner" : testUser['username'],
"name" : "Test Album"
}
testImagePath = os.path.join(settings.BASE_DIR, 'test_image_folder/test_image.jpg')
testPhoto = {
"owner" : testUser['username'],
"album" : testAlbum['name'],
"name" : "Test Photo",
"image" : SimpleUploadedFile(name='test_image.jpg', content=open(testImagePath, 'rb').read(), content_type='image/jpeg')
}
