It's somewhat old but there is a great series of blog posts about testing
Storm topologies using Clojure:

and if you take a look at Storm's testing.clj file, there are some great
Clojure utilities used for testing within Storm itself:

I learned a bunch by reading the multilang test cases here as a starting

and then learning more about the Clojure DSL:

Of course, if you're a Java programmer, you may be looking at all this
Clojure-based testing infrastructure and saying, "Great, now I have two
problems -- my unit tests, and learning Clojure." Indeed :) But, Clojure is
a pretty nice language and worth learning for use cases like this.
