Spec validation failures break the runner

[arichiardi]

Hello folks/weavejester 😄

It seems that spec validations break. I am using eftest.runner from within boot and I see the following when spec does not validate:

Uncaught exception, not in assertion.
expected: nil
  actual: 
clojure.lang.Compiler$CompilerException: java.lang.ClassCastException: eftest.runner$synchronize$fn__2894 cannot be cast to clojure.lang.MultiFn, compiling:(clojure/test/check/clojure_test.cljc:95:1)

2/2   100% [==================================================]  ETA: 00:00

All good in vanilla boot.test where I can see the failure properly. Of course eftest feels like a faster/better testing tool so I will try to investigate more.

Missing ex-data is probably because Boot/Bat-test running eftest inside a pod. No easy solution, because exceptions can't be thrown from pod back to boot main context, boot-cljs does some magic to serialize, deserialize and rethrow exceptions but that has lots of problems also. Anyway, this is probably not problem in eftest core.
