Question

我有这个简单的控制器：

＆＃39;使用严格的＆＃39;;

angular.module('feedsSnapshotsApp').controller('feedEditCtrl', function ($scope, lakesService) {

        $scope.getDataForLakes= function(){
            lakesService.query().then(function(result){
                $scope.model.lakes = result.lakes;
            });
        };
})
;

我想做以下事情：

我想测试函数是否正常工作：我想在我的测试单元中模拟服务，并为＆＃34; lakesService.query＆＃34;返回一个模拟的承诺。为了做到这一点，我该如何实现这一目标呢？

var scope;
beforeEach(module('feedsSanpshotApp')); 
beforeEach(inject(function($rootScope, $controller, $q) {
    scope = $rootScope.$new();
    scope.model = {
        lakes: undefined
    };
    var lakesServiceMock = {
        query: function () {
            var deferred = $q.defer();
            deferred.resolve('modelLakes'); // put the result you want to be resolved here
            return deferred.promise;
        };
    };
    var mock = {
        $scope: scope,
        lakesService: lakesServiceMock
    };
    $controller('feedEditCtrl', mock);
}));

it('test', function (done) {
    scope.getDataForLakes();
    expect(scope.model.lakes).toBe('modelLakes');
    done();
});

我如何模拟控制器内部的服务，并处理承诺？
