Unit tests for multiple processors

[Phil H]

Hi there,

I use the built in unit tests in the maven processor archetype for each of
my processors, but I would like to set up some integration testing using
multiple processors.

Is this possible? If so, anyone care to sling me some example code? Eg: say
I wanted to run a test connecting GenerateFlowFile’s output to PutFile’s
input.

Thanks!
Phil
