        """Verify whether content served by pulp can be downloaded.

        The process of publishing content is more involved in Pulp 3 than it
        was under Pulp 2. Given a repository, the process is as follows:

        1. Create a publication from the repository. (The latest repository
           version is selected if no version is specified.) A publication is a
           repository version plus metadata.
        2. Create a distribution from the publication. The distribution defines
           at which URLs a publication is available, e.g.
           ``http://example.com/content/foo/`` and
           ``http://example.com/content/bar/``.

        Do the following:

        1. Create, populate, publish, and distribute a repository.
        2. Select a random content unit in the distribution. Download that
           content unit from Pulp, and verify that the content unit has the
           same checksum when fetched directly from Pulp-Fixtures.
