angularjs - Throw error in error function of $http causes $digest already in progress in unit test -

here plunker showing issue:

here plunker error commented out in both scripts.js , scripts.spec.js , don't $digest error anymore:

throwing , testing errors seems work when not inside callback of $http request. know why might not working?

the problem mock $exceptionhandler service re-throws exceptions default. exception causing $rootscope.$apply aborted in middle.

one solution switch mock $exceptionhandlerprovider 'log' mode , check $exceptionhandler.errors. see here.
