clojure - Midje print stacktrace when test fails -

-

i learning clojure, , trying use tdd *.

i use midje testing library. love far, expected versus actual results display helpfull.

but there way use clojure.tools.trace or similar print trace of first test fails ?

*: specifically, remember seeing talk robert c. martin transformation priority premise, , i'm implementing factorial function way. there isn't yet code show though.

one possibility writing own emitter might overkill specific goal.

alternatively, can monkey-patch function responsible formatting expected values:

(require '[midje.util.exceptions :as e]          '[midje.emission.plugins.util :as u])  (defn- format-captured-throwable   [ex]   (if (e/captured-throwable? ex)     ;; ... adjust needs ...     (pr-str 'this-is-your-exception (e/throwable ex))))  (alter-var-root   #'u/attractively-stringified-value   (fn [f]     #(or (format-captured-throwable %) (f %))))

format-captured-throwable has produce string, though, meaning directly printing stacktrace let end near midje's test report. 

user=> (fact (throw (exception. "khaaaaaaaan.")) => :not-khan)  fail @ (form-init4689442922606051135.clj:1)     expected: :not-khan       actual: this-is-your-exception #<exception java.lang.exception: khaaaaaaaan.>
