The ImageCollectionTest.test_pull_multiple test performs a `docker pull` without
a `:tag` specified) to pull all tags of the given repository (image).
After pulling the image, the image(s) pulled are checked to verify if the list
of images contains the `:latest` tag.
However, the test assumes that all tags of the image are tags for the same
version of the image (same digest), and thus a *single* image is returned, which
is not always the case.
Currently, the `hello-world:latest` and `hello-world:linux` tags point to a
different digest, therefore the `client.images.pull()` returns multiple images:
one image for digest, making the test fail:
=================================== FAILURES ===================================
____________________ ImageCollectionTest.test_pull_multiple ____________________
tests/integration/models_images_test.py:90: in test_pull_multiple
assert len(images) == 1
E AssertionError: assert 2 == 1
E + where 2 = len([<Image: 'hello-world:linux'>, <Image: 'hello-world:latest'>])
This patch updates the test to not assume a single image is returned, and instead
loop through the list of images and check if any of the images contains the
`:latest` tag.
