Hi,

Following the examples, I tried this:
```
@Test(groups = "unit", testName = "ConsolesApiMockTest")
public class ConsolesApiMockTest extends BaseOpenStackMockTest<NovaApi> {
   public void getVNCConsole() throws Exception {
      String serverId = "5f64fca7-879b-4173-bf9c-8fa88330a4dc";

      MockWebServer server = mockOpenStackServer();
      server.enqueue(addCommonHeaders(new MockResponse().setBody(stringFromResource("/keystoneAuthResponse.json"))));
      server.enqueue(addCommonHeaders(new MockResponse().setBody(stringFromResource("/extension_list_full.json"))));
      try {
         NovaApi novaApi = api(server.getUrl("/").toString(), "openstack-nova");

         String zoneId = getFirst(novaApi.getConfiguredZones(), "RegionTwo");

         Optional<? extends ConsolesApi> consolesApi = novaApi.getConsolesExtensionForZone(zoneId);

      ...
      } finally {
         server.shutdown();
      }
   }
}
```
and I get an exception 
```
org.jclouds.http.HttpResponseException: CacheLoader returned null for key [identity=jclouds:joe, credential=letmein]. connecting to GET https://az-1.region-a.geo-1.compute.hpcloudsvc.com/v1.1/3456/extensions HTTP/1.1
	at org.jclouds.http.internal.BaseHttpCommandExecutorService.invoke(BaseHttpCommandExecutorService.java:162)
	at org.jclouds.rest.internal.InvokeSyncToAsyncHttpMethod.invoke(InvokeSyncToAsyncHttpMethod.java:129)
...
```

which is caused in `novaApi.getConsolesExtensionForZone(zoneId)` because it's trying to actually connect to the publicURL for the specific zone. I don't know how to proceed from this point, so once more I ask for your help!
