How to test topologies properly

[pwozniak]

Hi,

I have my Storm 1.1.3 cluster with some topologies that I would like to 
test (as a hole).


1. How (in general) should it be done. Maybe I should run the topology 
in the LocalCluster or use test framework dedicated for this 
(org.apache.storm.testing)?

2. TBH I have some tests for my topology that are using test framework 
(for example classses like:MkClusterParam, Testing.withLocalCluster, 
...) but I cannot find any reasonable tutorial, description how it 
should be used. Can you provide me such a tutorial or another source 
where I can find our how to use this framework?

3. What about the mocking? Some of my bolts uses some external 
resources. How I can mock communication like this?
