Hyperledger Sawtooth XO test case hangs on execution

Question

I'm attempting to use nose2-3 to run the sawtooth xo tp unit tests, but the code is hanging. When I Ctrl-C out, the below is displayed. Basically, the TP test case makes a call to register the mock validator, and that call never returns because the ZMQ Poller is waiting for something.

I'm on Ubutnu 16 LTS using Python 3.5.2 and rebased with hyperledger/sawtooth-core last week, so I'm running a straightforward configuration with the latest code.

What am I doing wrong here?

Thanks.

Have you tried running Dockerfile-tests-installed in the same directory? These tests are mainly for automated use with a complete test environment all set up. See Jenkinsfile in the top level github directory.

If you just want to run it and try it out, you can run it in Ubuntu or with Docker following these instructions: https://sawtooth.hyperledger.org/docs/core/releases/latest/app_developers_guide/installing_sawtooth.html

Basically you install Sawtooth, Docker, docker-compose, and run: docker-compose -f sawtooth-default.yaml up

You can then run Sawtooth commands from a Docker shell with: docker exec -it sawtooth-shell-default bash
