no stacktrace & test abort in phantomjs

[laurentsenta]

Hi again, I have another problem, using phantomjs:

With the same setup that in #58 but without :js-env option, I get

• an error with no stack-trace nor info on where to look for
• the test runner seem's to abort, I have half a dozen namespaces that do not show up.

Here's the output:

I rely a lot on core.async and async tests, could this be an issue?
Thanks again for taking a look,

👍 running into the same issue and it makes it difficult to debug failing tests

This is helping me get at stack traces in tests

(ns stack-trace.api
 (:require
  clojure.string))

(defn print-phantom-trace
 [trace]
 (let [process-line (fn [s] (clojure.string/replace s #"file:.*generated_test_suite\.out" " ... "))]
  (doseq [l (map process-line (clojure.string/split-lines trace))]
   (prn l))))

(defn trace-pred
 [pred]
 (try
  (when-not (pred)
   (throw (js/Error. "fail")))
  (catch js/Error e
   (print-phantom-trace (.-stack e)))))
