If it's running on devapi:
../germinator/ws-tests/run_tests.sh https://devapi.opentreeoflife.org
It's also possible to just run it locally, something like this:
(create files or symlinks 'ott' and 'synth.tre' in services directory)
services/service start
../germinator/ws-tests/run_tests.sh localhost: host:translate=true
