Clojure testing with multiple test files

Like Java, and probably because it uses Java, Clojure/clojure.test/lein test appear to use naming requirements to run tests. I wanted to use multiple files to store and run tests from:

.../tests/core_test.clj
.../tests/ch5_test.clj

Simply adding a file in the tests directory didn’t allow that. I researched this, and I learned pretty much everything but what to do here. I learned that I could

Exciting! At some point while looking at all this, I thought of use, and how that would bring the test forms from another namespace. use-ing tests from the other files/namespaces probably isn’t the “right” way, but until I learn what to do, this is what I’m going to do.
