unit-testing – 如何使用$location服务单元测试angularjs控制器

我试图创建一个简单的单元测试，测试我的show函数。

我得到以下错误：

TypeError: Object #<Object> has no method 'show'

似乎$ rootScope不是控制器的范围？

这是我的控制器：

function OpponentsCtrl($scope,$LOCATIOn) {
    $scope.show = function(url) {
        $LOCATIOn.path(url);
    }
}
OpponentsCtrl.$inject = ['$scope','$LOCATIOn'];

这里是我的控制器单元测试：

describe('OpponentsCtrl',function() {
    beforeEach(module(function($providE) {
        $provide.factory('OpponentsCtrl',function($LOCATIOn){
            // whatever it does...
        });
    }));

    it('should change LOCATIOn when setTing it via show function',inject(function($LOCATIOn,$rootScope,OpponentsCtrl) {
        $LOCATIOn.path('/new/path');
        $rootScope.$apply();
        expect($LOCATIOn.path()).toBe('/new/path');

        $rootScope.show('/test');
        expect($LOCATIOn.path()).toBe('/test');
    }));
});

describe('OpponentsCtrl',function() {

    var LOCATIOn;

    beforeEach(module(function($providE) {
        $provide.factory('OpponentsCtrl',function($LOCATIOn){
            LOCATIOn = $LOCATIOn;
        });
    }));

    it('should change LOCATIOn when setTing it via show function',inject(function() {    
        spyOn(LOCATIOn,'path');    
        expect(LOCATIOn.path).toHaveBeenCalledWith('/new/path');
    }));
});
