AssertionError: 'image/bmp' is not None

Probably the cause is the change of library Pillow added few days ago.
https://github.com/python-pillow/Pillow/commit/fe18b039ca9e11c6deed8f21a9e5eca815badbb7

My Pillow version is 2.9.0, so the content_type is "image/bmp" and is not None.

The original purpose of this test is to check the case when Pillow doesn't detect the MIME type of the image, so we need to find a new case of that if possible.

Replying to timgraham:

The original purpose of this test is to check the case when Pillow doesn't detect the MIME type of the image, so we need to find a new case of that if possible.

Then, should I choose a different type of image which Pillow doesn't detect the MIME type? Or can I set file extension which doesn't exist?

I found a tga file can be ImageFile and its MIME type is not detected, so I changed bmp to tga.

comment:6 by Andriy Sokolovskiy, 9 years ago

Yes, after previous ticket I added MIME for BMP, so it will fail.
I think it is better to use mock to model this situation instead of fixing every time after Pillow registers MIME for image plugin without it.
