> Gremlin Server spawned by test suites should use a different port
> -----------------------------------------------------------------
>
> Key: TINKERPOP-1538
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1538
> Project: TinkerPop
> Issue Type: Improvement
> Components: server, test-suite
> Affects Versions: 3.2.3
> Reporter: Daniel Kuppitz
>
> The Gremlin Server instance spawned by test suites should use a different
> port (if the default port is already in use). You get all kind of test
> errors, if something else (even another Gremlin Server instance) is already
> using the default port.
