javascript - Jasmine object “has no method 'andReturn'” -

-

beginner jasmine, first attempt jasmine spies. thought mimicking format displayed here (search: "andreturn"), i'm getting error can't work out:

typeerror: object function () {         calltracker.track({           object: this,           args: array.prototype.slice.apply(arguments)         });         return spystrategy.exec.apply(this, arguments);       } has no method 'andreturn'

no clue i'm doing wrong. here's spec:

describe('die', function() {     it('returns value when roll it', function() {         var die = object.create(die);         spyon(math, 'random').andreturn(1);         expect(die.roll()).toequal(6);     }); });

and corresponding js:

var die =  {        roll: function() {         return math.floor(math.random() * 5 + 1);     } }

thanks help!!!

jasmine 2.0 changed of spy syntax. jasmine 2.0 docs

spyon(math, 'random').and.returnvalue(1);
