For me tests are not failing, and are also not failing on Travis.
But I managed to make them fail on my local machine by setting datastore.elasticsearch.index.refresh_interval
from 5 to 1. Which is odd, if I set it to lower value the failure is something like:
Result message has a wrong size! expected:<1> but was:<5>
and that is exactly opposite of errors on eclipse CI.
So, the issue is most probably as already mentioned on insert / query time frame.
Maybe, we could solve this issue by this configuration parameter? Finding a sweet spot for index delay.
Sleep / waits in tests are newer good idea, thou I use them to
☹

Maybe you can consider using Awaitility [1] for this purpose? This is usually a good replacement for Thread.sleep().
I can see the same issues on our internal CI system.
Maybe you can re-try for a specific amount of time. That way you could abort early if everything works fine.

I suggest to increase, in the test, the wait time before querying.
May be related to the load of the machine, so in some cases Elasticsearch is not able to update indexes before the test query.
What do you think (currently the test waits for the Elasticsearch refresh time between the insert operation and the subsequent querying)
Build works OK on my machine, but it seems to fail intermittently on Hudston. We should try to investigate it.
Just look at the Hudson build right now [1].

Hi Jens,
from our side we didn’t experienced failure on datastore test. Do you have a stacktrace to help us investigating a possible issue?
for me the unit test `org.eclipse.kapua.service.datastore.internal.MessageStoreServiceTest.testMessageOrderingMixedTest` is failing quite often.
Is that just me? Or does it fail for others as well?
Is there something that can be done about it? Fixing the unit test? Fixing the actual code?
Thanks
Jens
