When I run the Ceilometer test suite with the command "tox -e py27", I get 159 ConnectionFailure errors for the MongoDB tests.

The traceback for all of these errors is:

Traceback (most recent call last):
  File "/opt/stack/ceilometer/ceilometer/tests/base.py", line 71, in skip_if_not_implemented
    return func(*args, **kwargs)

    raise ConnectionFailure(str(e))
ConnectionFailure: connection closed

There is also an odd message "No module named deprecated" at the end of the test results.

If I increase the maximum number of MongoDB connections in the --maxConns argument to mongod in run-tests.sh, the errors go away, but I still get the "No module named deprecated" message.
