KNOX-1049 - check for null topology to avoid NPE in tests
> Default Service or App Context for Topologies

> Key: KNOX-1049
> URL: https://issues.apache.org/jira/browse/KNOX-1049

> In order to help reduce the complexity and level of granularity of the UI
> related rewrite rules, it would be good to be able to have UIs deployed to
> their own topology that has implied context paths. For instance, when
> authoring the rewrite rules for something like Ambari, we need to add the
> "ambari" path element in front of every relative path.
> Coupled with the need to do this and the need to disambiguate a relative url
> like images/log.gif between one app another, we end up with a rewrite rule
> for every single link in a UI.
> So, if we can limit UIs to their own topology then we shouldn't have to add
> "ambari" in front of each link in rewrite rules. But in order to match a
> topology path in the GatewayFilter we will need to know the missing path
> element.
> This JIRA is an attempt at coding this into the topology.
