testing context not displayed in test output

[Dexterminator]

It seems like only the cljs.test/testing-vars-str is used in:

karma-reporter/src/jx/reporter/karma.cljs

Lines 58 to 72 in 2c268b4

	(defn- format-log [{:keys [expected actual message] :as result}]
	(let [indentation (count "expected: ")]
	(str
	"FAIL in " (cljs.test/testing-vars-str result) "\n"
	(if (and (seq? expected)
	(seq? actual))
	(str
	"expected: " (format-fn indentation expected) "\n"
	" actual: " (format-fn indentation (second actual)) "\n"
	(when-let [diff (format-diff indentation expected (second actual))]
	(str " diff: " diff "\n")))
	(str
	expected " failed with " actual "\n"))
	(when message
	(str " message: " (indent indentation message) "\n")))))

The cljs.test/testing-contexts-str should be displayed as well in order to get any value from using the (testing) macro.
