Camel NMR dependencies

[Vinny]

Hello,
Trying to test some of my nmr routes. I've looked at
http://camel.apache.org/nmr.html
and have looked at the test example at the bottom. The problem is I can't
seem to locate the dependency that supplies the AbstractComponentTest class
anywhere. Is there a maven dependency that is needed? Is this still the way
to test nmr routes or are there alternatives ?
TIA
Vincent
