I'm getting the exception com.google.appengine.api.datastore.DatastoreFailureException: Unexpected failure while trying to implement jBehave with Google App Engine. jBehave essentially runs on top of junit so I don't think jBehave itself is the problem.
This exception is thrown in about 1 out of every 3 runs of the test. I thought it might have been issues of consistency with the LocalServiceTestHelper so I tried configuring the LocalServiceTestHelper various ways which are supposed to ease testing by ensuring the data makes it to the database and can be read back for testing purposes.
Try #1:
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper((new LocalDatastoreServiceTestConfig()));
Try #2:
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper((new LocalDatastoreServiceTestConfig())
.setDefaultHighRepJobPolicyUnappliedJobPercentage(0));
Try #3:
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper((new LocalDatastoreServiceTestConfig())
.setApplyAllHighRepJobPolicy());
However all of these attempts led to the same problem, namely the DatastoreFailureException in approximately 1 out of every 3 runs of the test.
Here's a full stack trace:

Upgrading from JBehave 3.9.4 to 3.9.5 fixed this problem. It also resolved this problem: Plugin execution not covered by lifecycle configuration (JBossas 7 EAR archetype)
