单元测试 – 如何对Angular服务与$cookies的交互进行单元测试？

anagular-mocks让我们以与在代码中类似的方式在规范中配置我们的模块,除了不使用config函数,我们将函数作为第二个参数传递给我们用于调用模块的模块函数.茉莉花.

它看起来像这样：

describe ('my service',function () {
    var $cookieStore,myService

    beforeEach(module ('myModule',function ($provide) {
        // this function configures the "myModule" module before any
        // injectables are created.

        // We use a decorator to access the cookie store before other
        // services are instantiated.
        $provide.decorator ('$cookieStore',function ($delegate) {
            // at this point the "$cookieStore" service  has only just 
            // been constructed,and is accessible here as "$delegate".
            // Services that have "$cookieStore" as an injected
            // dependency have not been instantiated yet,so we
            // can slip our cookie in now.
            $delegate.put ('favorite-cookie','oatmeal');
            return $delegate;
        });
    }));

    beforeEach (inject (function (_$cookieStore_,_myService_) {
        myService = _myService;
        $cookieStore = _$cookieStore_;
    }

    it ('should interact with the pre-existing "favorite-cookie" cookie',function () {
        // your expectations go here.
    });

    afterEach(function() {
        // clean up
        $cookieStore.remove ('favorite-cookie');
    });


});
