angularjs – 创建单元测试,其中每个测试都有其特定的测试数据和

工作方式：

'use strict';
describe('lessonplannerFactory unit tests',function () {

    // load the service's module
    // beforeEach(module('clientApp'));

    // Arrange
    var dateFactory = {
        getVisibleDateRange: function (startDate,endDate,visibleWeekDays) {
            // I do not care about the parameters,I just want to stub out the visible days with 2 stubs
            var days = [ moment(new Date(2014,1)),moment(new Date(2014,2))];
            return days;
        }
    };

    // load the service's module
    beforeEach(module('clientApp',function ($provide) {
        $provide.value('dateFactory',dateFactory);
    }));

    // Arrange
    var lessonPlannerFactory;
    beforeEach(inject(function (_lessonPlannerFactory_) {  // The underscores before/after the factory are removed by the $injector
        lessonPlannerFactory = _lessonPlannerFactory_;
    }));

    it('creates periods by a daily rotation of n according to a given timetable for a certain timespan',inject(function (_dailyPeriodsTestDataFactory_) {

        // Arrange
        var testCases = _dailyPeriodsTestDataFactory_.testCases;  // specific test data

        // Act
        // Do something with the injected lessonPlannerFactory.method1(testCases[0],..);

        // Assert

    }));
});

我想要的是用我自己的话或伪代码描述的：

describe("lesson planner factory unit tests")
{

   // Inject a lesson planner factory instance for each test

test1(_specificTestData1_)
{
    // Arrange
    var data = _specificTestData1_;

    var stub1 = { } // setup specific stub

    inject this specific stub into this test with $provide.value = mock // This stub is used INSIDE the method1 to stub out a factory dependency

    // Act
    var result = lessonPlannerFactory.method1(data,..);

    // Assert

}

test2(_specificTestData2_)
{
    // Arrange
    var data = _specificTestData2_;

    var stub2 = { } // setup specific stub

    inject this specific stub into this test with $provide.value = mock // This stub is used INSIDE the method2 to stub out a factory dependency

    // Act
    var result = lessonPlannerFactory.method2(data,..);

    // Assert

}

}

这就是我尝试过的,但它不起作用.

我认为在测试中的这一点上将存根分配给$provide.value为时已晚,因为之前注入/创建了lessonPlannerFactory,并且lessonPlannerFactory将真正的存根对象作为依赖项.只是看看：

'use strict';
describe('lessonplannerFactory unit tests',function () {

    // load the service's module
    beforeEach(module('clientApp'));

    // Arrange
    var lessonPlannerFactory;
    beforeEach(inject(function (_lessonPlannerFactory_) {  // The underscores before/after the factory are removed by the $injector
        lessonPlannerFactory = _lessonPlannerFactory_;
    }));

    it('creates periods by a daily rotation of n according to a given timetable for a certain timespan',inject(function (_dailyPeriodsTestDataFactory_) {

        // Arrange
        var testCases = _dailyPeriodsTestDataFactory_.testCases;  // specific test data

        // specific test stub
        var dateFactory = {
            getVisibleDateRange: function (startDate,visibleWeekDays) {
                // I do not care about the parameters,I just want to stub out the visible days with 2 stubs
                var days = [ moment(new Date(2014,2))];
                return days;
            }
        };

        // load the stub
        module('clientApp',function ($provide) {
            $provide.value('dateFactory',dateFactory);
        });

        // Act          on the testcases in a for loop
        var result = lessonPlannerFactory.createPeriodsDaily(testCases[i].data1,..);

        // Assert
    }));
});

多数民众赞成我得到的错误：

TypeError: Cannot read property 'running' of undefined
    at isSpecRunning (http://localhost:3000/base/app/bower_components/angular-mocks/angular-mocks.js:1924:65)

那么我怎样才能为一个服务依赖注入一个存根而不是在beforeEach方法中,而是在单元测试本身内部,因为我需要一个特定的存根！
