Aled Sage commented on BROOKLYN-272:
------------------------------------
Disabling {{ConfigYamlTest.testDeferredSupplierToAttributeWhenReady}} and
{{ConfigYamlTest.testDeferredSupplierToAttributeWhenReadyInSpecialTypes}}.
The {{entity.config().getNonBlocking()}} can return absent. When it's called
with
a deferred supplier value, it will kick off a task and then wait just a few
millis for that
task to execute deferredSupplier.get(). If it times out, then it returns
Maybe.absent.
However, on apache jenkins the machine is often slow so the task doesn't
complete in the
given number of millis (even though deferredSupplier.get() doesn't need to
block for anything).
> Non-deterministic test failures in jenkins

> Key: BROOKLYN-272
> URL: https://issues.apache.org/jira/browse/BROOKLYN-272
> Project: Brooklyn
> Issue Type: Bug
> Reporter: Aled Sage
>
> There are several non-deterministic tests that fail occasionally in the
> apache jenkins build. We should fix those tests: either the underlying bug if
> there is one, or the way to the test has been written to make it more
> deterministic.
> Having build failures unrelated to the changes being made in a PR (and on
> master) is extremely disruptive for development. We must avoid that wherever
> possible.
> I therefore suggest we disable these non-deterministic failing tests
> immediately, and use this jira issue to track fixing them. We can annotate
> the tests with
> {noformat}
> @Test(groups={"WIP", "Non-deterministic-failure"})
> {noformat}
> to make them easy to find. (note the "Non-deterministic-failure" group is
> not used by any profiles, it's just there for searching purposes).
> The tests I have identified from recent build failures are:
> * {{BasicStartableTest.testTransitionsThroughLifecycles}} - see
