testing println in clojure.test

[Kevin Kleinfelter]

I've got a function which is supposed to println a computed value.  How do I test whether it printed that value, when using clojure.test?

Or, another way of asking the same question is how do I grab the output from println when testing a function with clojure.test?

TIA

The with-out-str macro should be able to do this for you.  A few examples of use can be found on ClojureDocs here:

https://clojuredocs.org/clojure.core/with-out-str

You may find the Clojure cheat sheet useful for discovering things like this (at least for things the cheat sheet includes -- it doesn't cover any but a tiny handful of functions outside of Clojure core functionality).  In particular for your question, the section titled "IO" (i.e. Input/Output), subsection "to string" would have helped:
