I disagree; these tests are basically asking the question:
"Can the validateTerminologyInORU_R01 method take an ORU_R01 encounter and validate each and every terminology element in the encounter using _some_ CodeValidator?"

So we're not trying to see if our CodeValidator itself is working, we're trying to ensure that the "unit logic" of this method is working. Our CodeValidator implementation needs to be tested separately. Remember that this method doesn't know how the CodeValidator is implemented, that's not it's concern.

I haven't added a test for the Mule code validator, since all it does is kick of a request to the apelon flow. Issue #85 covers the functionality of the flow. However with Issue #85 completed now we can maybe add a test to see that the code validator itself behaves correctly (even if it's just a few lines). We'll have to do this as a new issue though. What do you think?
