angularjs – 间隔函数,当角度控制器初始化时执行

我想测试以下函数实际上是使用茉莉花调用该控制器的初始化。似乎使用间谍是一种方式，它只是不能像我所期望的那样工作，当我把它的期望在“它”块被调用。我想知道是否有一种特殊的方法来检查在调用范围函数中是否调用了某些东西，但是在控制器本身中。

App.controller('aCtrl',[ '$scope',function($scope){

    $scope.loadResponses = function(){
        //do something
    }

    $scope.loadResponses();

}]);

// spec文件

describe('test spec',function(){

    beforeEach(
    //rootscope assigned to scope,scope injected into controller,controller instantiation.. the expected stuff

        spyOn(scope,'loadResponses');
    );

    it('should ensure that scope.loadResponses was called upon instantiation of the controller',function(){
         expect(scope.loadResponses).toHaveBeenCalled();
    });
});

$scope.loadResponses = function(){
    //do something
}
// <-- You would need your spy attached here
$scope.loadResponses();

var scope;
beforeEach(inject(function($controller,$rootScope) {
    scope = $rootScope.$new();
    $controller('aCtrl',{$scope: scope});
    scope.$digest();
}));
it("should have been called",function() {
    spyOn(scope,"loadResponses");
    scope.doTheStuffThatMakedLoadResponsesCalled();
    expect(scope.loadResponses).toHaveBeenCalled();
});
