Public bug reported:

Hi,

Building Horizon in Debian Stretch is no problem, and all unit test
pass. Unfortunately, under Python 3.7 in Debian Sid, it doesn't even
start to run unit tests:

Could someone from the Horizon team help me to find the solution? I need
this to be fixed in order to have Horizon for Debian Buster.
