Hi everyone! I'm working on some test that use a java object. I'm thinking it would be nice to mock that out. I've gathered that reify might be the best way to do this. This is how I'm trying to wire up my test

(let [mock (reify LDClientInterface (allFlags [client ld-user] "flags"))]
      (with-redefs-fn {#'my-ns/init-client (fn [] mock)} ;; line 10
        #(is= (my-ns/foo) false))
      )

java.lang.ClassCastException: circle.util.test_launchdarkly$fn$reify__106395 cannot be cast to clojure.lang.IFn
