# About tests and tornado
# Upstreams claims to work fine with tornado 5, and it's indeed possible to
# launch a cluster with tornado 5 installed, but tests definitely don't run with
# tornado 5 installed. Upstreams CI runs with tornado 4. This is why we limit
# ourselves to <tornado-5 when running tests.
