将服务模拟到控制器中

Question

我正在尝试使用 Jasmine 2.2.0 模拟服务：CheckoutService.patch() returns 我的 CheckoutController:

describe('CheckoutController', function() {
    var $scope, vm, checkoutServiceMock, def;

    beforeEach(function(){
        module('app');

        checkoutServiceMock = jasmine.createSpyObj('CheckoutService', ['patch']);

        inject(function($rootScope, $controller, $q){
            def = $q.defer();

            $scope = $rootScope.$new();

            vm = $controller('CheckoutController', {
                $scope: $scope,
                CheckoutService: checkoutServiceMock
            });

            checkoutServiceMock.patch.andReturn(def.promise);
        });
   });
});

但我得到：TypeError: 'undefined' is not a function (evaluating 'checkoutServiceMock.patch.andReturn(def.promise)')

我错过了什么？

Answer 1

我猜你应该把andReturn改成and.callfake()，例如：

spyOn(checkoutServiceMock, "patch").and.callFake(function() {
  return def.promise;
});

有关 Jasmine 2.2，请参阅 docs。
