Based on the definition of a unit here, how would you then define/describe an integration test?

I agree that too many small tests can be bad, and not every function requires a test, however, I was under the impression that the image you have under ["So What is a UNIT"](craftbettersoftware.com…), the image on the left IS-A unit test and the image on the right IS-AN integration test.

Would love to hear your thoughts on this. Thanks!
