为什么我会收到错误…意外请求：GET / internalapi / quotes

Question

我在我的角度应用程序中定义了以下服务：

services.factory('MyService', ['Restangular', function (Restangular) {
       return {
           events : { loading : true },

           retrieveQuotes : function() {
               return Restangular.all('quotes').getList().then(function() {
                   return { hello: 'World' };
               });
           }
    };
}]);

我正在编写以下规范对其进行测试：

describe("MyService", function () {

    beforeEach(module('MyApp'));
    beforeEach(module("restangular"));

    var $httpBackend, Restangular, ms;

    beforeEach(inject(function (_$httpBackend_, _Restangular_, MyService) {
        ms = MyService;
        $httpBackend = _$httpBackend_;
        Restangular = _Restangular_;
    }));


    it("retrieveQuotes should be defined", function () {
        expect(ms.retrieveQuotes).toBeDefined();
    });

    it("retrieveQuotes should return array of quotes", function () {

        $httpBackend.whenGET("internalapi/quotes").respond({ hello: 'World' });
        ms.retrieveQuotes();
        $httpBackend.flush();
    });

});

每当我运行测试时，第一个测试通过，但第二个测试产生错误：

Error: Unexpected request: GET /internalapi/quotes

我究竟做错了什么？

编辑：

原来，我已经配置Restangular是这样的…
RestangularProvider.setBaseUrl("/internalapi");。但是我在打电话给我internalapi/quotes。注意缺少“
/”。一旦我添加了斜线，/internalapi/quotes一切都很好:)

您需要告诉$ httpBackend期待GET请求。

describe("MyService", function () {

   beforeEach(module('MyApp'));
   beforeEach(module("restangular"));

   var Restangular, ms;

    beforeEach(inject(function (_Restangular_, MyService) {
        ms = MyService;

        Restangular = _Restangular_;
    }));


    it("retrieveQuotes should be defined", function () {
        expect(ms.retrieveQuotes).toBeDefined();
    });

    it("retrieveQuotes should return array of quotes", inject(function ($httpBackend) {

        $httpBackend.whenGET("internalapi/quotes").respond({ hello: 'World' });

        //expect a get request to "internalapi/quotes"
        $httpBackend.expectGET("internalapi/quotes");

        ms.retrieveQuotes();
        $httpBackend.flush();
    }));

});

或者，您可以穿上自己respond()的衣服expectGET()。我更喜欢whenGET()用beforeEach()那种方式陈述我的陈述，而不必在每个测试中都定义响应。

        //expect a get request to "internalapi/quotes"
        $httpBackend.expectGET("internalapi/quotes").respond({ hello: 'World' });

        ms.retrieveQuotes();
        $httpBackend.flush();
