javascript - currentSpec in Jasmine 2 is undefined -

i want upgrade test suite latest jasmine version 2.3.4. have custom helper methods testing angularjs stuff inside spy_helper.js this:

(function() {   this.stubpromise = function(service, functionname) {     var $q = jasmine.getenv().currentspec.$injector.get("$q")     var $rootscope = jasmine.getenv().currentspec.$injector.get("$rootscope")      var deferred = $q.defer();     var spy = spyon(service, functionname).andreturn(deferred.promise);     spy.andresolvewith = function(value) {       deferred.resolve(value);       $rootscope.$apply();       return spy;     };     spy.andrejectwith = function(value) {       deferred.reject(value);       $rootscope.$apply();       return spy;     };     return spy;   }; }).call(this);  // inside test can stubpromise(someservice, 'foobar').andresolvewith("test"); 

the helper stubs promise , resolves or rejects promise. have bunch of such helpers.

the problem jasmine 2 is, jasmine.getenv().currentspec undefined. intended jasmine 2 developers, far know.

but how adapt helpers jasmine 2? extend arguments $injector or $q , $rootscope, result in unhandy tests stubpromise(someservice, 'foobar', $injector).andresolvewith("test"); , have inject $injector on top of every test.

so, there way angular's $injector inside helpers?

furthermore in other helpers, need catch after method of spec, check if expected spies on promises called jasmine.getenv().currentspec.after(flush);

any appreciated, because helpers saved me lot of time, , i'd not happy rewrite of them or throw them out. maybe there library out there, similar (and didn't know it).
