# TODO check both 5001 and 5002.
# 5001 should have a readable gateway (part of the API)
# 5002 should have a readable gateway (using ipfs config Addresses.Gateway)
# but ideally we should only write the tests once. so maybe we need to
# define a function to test a gateway, and do so for each port.
# for now we check 5001 here as 5002 will be checked in gateway-writable.
