[jira] [Commented] (OLINGO-767) TriPinService Test fails sometimes in maven build

["aki yoshida (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OLINGO-767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14712928#comment-14712928 ] 

aki yoshida commented on OLINGO-767:
------------------------------------

Could this be of the port that the test is used?

I noticed that many (maybe all) tests on olingo are using some
constant port number instead of generating a free port number.

Maybe this is not related directly to the actual problem of
TripPinService, but I had often problems in running the olingo
builds/tests where something else is running.

So, I think it would be nice to have a test utility class somewhere in
oligo so that any test can use it to find a free port to run its
tests?.
here is such a utility class used in apache camel.
https://github.com/apache/camel/blob/master/components/camel-test/src/main/java/org/apache/camel/test/AvailablePortFinder.java
