How do I test $scope.$on in AngularJS

Question

How do I test that the scope is populated after the broadcast? I\'ve searched and found a few QA\'s here in stackexchange, but none answered my problem. The code is working

Answer 1

If want to fake the returnValue from $scope.$broadcast() you can do something like these two cases:

Case 1:

scope.$broadcast('TEST_CHANGED', {test: 'test1'});
spyOn(scope, '$broadcast').and.callThrough();
expect(something).toEqual('something');

Case 2:

scope.$broadcast('TEST_CHANGED', {test: 'test2'});
spyOn(scope, '$broadcast').and.callThrough();
expect(something2).toEqual('something2');
