Description

Running a single-host setup similar to system_tests_edge_router RouterTest. See config generator script gen_configs.py attached. The test case uses current proton cpp examples to generate traffic.

 

1. ./gen_configs.py
2. Start the routers by running ./run-ratchet.sh
3. simple_recv -a amqp://127.0.0.1:21009/closest/foo -m 100000000
4. simple_recv -a amqp://127.0.0.1:21012/closest/foo -m 100000000
5. simple_send -a amqp://127.0.0.1:21009/closest/foo -m 100000000
6. kill receiver on port 21009. This produces the core.
