Just a question about test doubles - I'm wondering if there's a convenient library for creating mock functions. Googling around this seems to lead to a lot of options that focus on redefining vars, but that's what I'm trying to avoid. Basically I'm looking for jest.fn only in Clojure, which you could sort of use like:

(let [f (create-stub)]
  (do-thing! f)
  (is (= (call-count f) 1))
  (is (= (args-for-call f 0) [:foo :bar])))

I'd like announce https://github.com/danielmiladinov/burpless, a library I just released, for facilitating writing cucumber tests from Clojure
