commit acfda9c26df888741805249f3ec0f60f369fc664
Author: Louis Sautier <sautier.louis@gmail.com>

    Tests: allow differences when reading a buffer or a file, fixes #173
    
    Also remove the loop in order to avoid analyzing files or buffers for each
    expected value, replace it with a call to assertIn().
