单元测试 – 如何使用jasmine模拟Angular服务？

这可能是重复的,但我在这里看了很多其他问题,他们通常会以某种方式错过我正在寻找的东西.他们主要谈论他们自己创造的服务.我能做到并做到了.我试图覆盖我的模拟注入的角度.我认为它会是相同的,但由于某些原因,当我单步执行代码时,它始终是角度$cookieStore而不是我的模拟.

我对jasmine和angularjs的经验非常有限.我来自C#背景.我经常编写单元测试moq(C#的模拟框架).我习惯看到这样的事情

[TestClass]
public PageControllerTests
{
    private Mock<ICookieStore> mockCookieStore;
    private PageController controller;

    [TestInitialize]
    public void SetUp()
    {
        mockCookieStore = new Mock<ICookieStore>();
        controller = new PageController(mockCookieStore.Object);
    }

    [TestMethod]
    public void GetsCarsFromCookieStore()
    {
        // Arrange
        mockCookieStore.Setup(cs => cs.Get("cars"))
                    .Return(0);

        // Act
        controller.SomeMethod();

        // Assert
        mockCookieStore.VerifyAll();
    }
}

我想模拟我在我的一个控制器中使用的$cookieStore服务.

app.controller('PageController',['$scope','$cookieStore',function($scope,$cookieStore) {

    $scope.cars = $cookieStore.get('cars');

    if($scope.cars == 0) {
            // Do other logic here
            .
    }

    $scope.foo = function() {
        .
        .
    }
}]);

我想确保使用’garage’参数调用$cookieStore.get方法.我也希望能够控制它的回馈.我希望它返回0然后我的控制器必须做一些其他逻辑.

这是我的测试.

describe('Controller: PageController',function () {

    var controller,scope,cookieStoreSpy;

    beforeEach(function () {
        cookieStoreSpy = jasmine.createSpyObj('CookieStore',['get']);
        cookieStoreSpy.get.andReturn(function(key) {
            switch (key) {
                case 'cars':
                    return 0;
                case 'bikes':
                    return 1;
                case 'garage':
                    return { cars: 0,bikes: 1 };
            }
        });

        module(function($provide) {
            $provide.value('$cookieStore',cookieStoreSpy);
        });
        module('App');

    });

    beforeEach(inject(function(_$httpBackend_,$rootScope,$controller) {
        scope = $rootScope.$new();
        controller = $controller;
    }));

    it('Gets car from cookie',function () {
        controller('PageController',{ $scope: scope });
        expect(cookieStoreSpy.get).toHaveBeenCalledWith('cars');
    });
});

locationMock = jasmine.createSpyObj('location',['path','search']);
locationMock.location = "";

locationMock.path.andCallFake(function(path) {
  console.log("### Using location set");
  if (typeof path != "undefined") {
    console.log("### Setting location: " + path);
    this.location = path;
  }

  return this.location;
});

locationMock.search.andCallFake(function(query) {
  console.log("### Using location search mock");
  if (typeof query != "undefined") {
    console.log("### Setting search location: " + JSON.stringify(query));
    this.location = JSON.stringify(query);
  }

  return this.location;
});

module(function($provide) {
  $provide.value('$location',locationMock);
});
