"""
A set of tests that can be run against a foreign AMQP 1.0 broker.
RUNNING WITH A FOREIGN BROKER:
1. Start the broker
2. Create persistent queues named: interop-a interop-b interop-q tx-1 tx-2
3. Export the environment variable QPID_INTEROP_URL with the URL to connect to your broker
in the form [user[:password]@]host[:port]
4. From the build directory run this test:
ctest -VV -R interop_tests
If QPID_INTEROP_URL is not set, a qpidd broker will be started for the test.
