--------------------------------------------------------------
[~jeffzhang] - rather than waiting for initStarted and then sleeping for 1
second, the test will be more robust if you wait for the expected FINAL state -
which is FAILED on most of the tests. The test will eventually timeout if the
state is not reached.
The sequence re-ordering in initialize() looks good though.
Eventually, it may be better to use one of the ControlledInputInitializers -
but that can wait for a separate jira.
