Traffic Light Controller Subscription

Tests

Subscription can be turned on and off for S0001

Check that we can subscribe to status messages. The test subscribes to S0001 (signal group status), because it will usually change once per second, but otherwise the choice is arbitrary as we simply want to check that the subscription mechanism works.

  1. subscribe
  2. check that we receive a status update with a predefined time
  3. unsubscribe
