Code review comment for lp:~epics-core/epics-gateway/dbe_props

I still get all tests failing, whether I use use 'make runtests' or 'nosetests --exe' in the pyTestsApp directory. This is the output to the end of the first test, the others give exactly the same traceback:

tux% nosetests --exe
EEEEEEE
======================================================================
ERROR: DBE_ALARM monitor on an ai with two alarm levels - crossing the level generates updates

Traceback (most recent call last):
  File "/local/anj/dbe_props/testTop/pyTestsApp/TestDBEAlarm.py", line 20, in setUp
    os.environ["EPICS_CA_ADDR_LIST"] = "localhost:{} localhost:{}".format(gwtests.iocPort,gwtests.gwPort)

======================================================================

Setting VERBOSE=YES shows the IOC starting and stopping (it looks like it could be starting the IOCs all at once, but that's probably just the order of capturing and displaying the stdout streams).

What could I be doing wrong?
