Hi, This is a problem I was working on this morning (with the help of
chouser, thank you!), and ended up with a 'with-private-fns' macro that
works like this:
(with-private-fns [org.foo.bar [fn1 fn2]]
(deftest test-fn1..)
(deftest test-fn2..))
I'm a Clojure greenhorn, but I like this approach because my private fn
tests are consolidated. I think in the end thought it boils down to a
matter of personal style :)
The macro itself looks like this:
(defmacro with-private-fns [[ns fns] & tests]
"Refers private fns from ns and runs tests in context."
`(let ~(reduce #(conj %1 %2 `(ns-resolve '~ns '~%2)) [] fns)
~...@tests))
A test file making use of it can be found here:

Cheers,
Alan
