Why do I receive error … unexpected request: GET /

问题:

I've defined the following service in my angular app :

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

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

and I'm writing the following spec to test it :

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();
    });

});

Whenever I run the tests, the first test passes but the second test produces the error :

Error: Unexpected request: GET /internalapi/quotes

What am I doing wrong?

EDIT:

It turned out I'd configured Restangular like so ... RestangularProvider.setBaseUrl("/internalapi");. But I was faking calls to internalapi/quotes. Notice the lack of the "/". Once I added the slash /internalapi/quotes all was good :)

You need to tell $httpBackend to expect a GET request.

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();
    }));

});

Alternatively you can put your respond() on your expectGET(). I prefer to put my whenGET() statements in a beforeEach() that way I do not have to define the response within every test.

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

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

I had the same problem as you guys. My solution was to add a '/' at the start of the URL-parameter of the .expectGET. Using your example:

$httpBackend.expectGET("/internalapi/quotes").respond({ hello: 'world'})

Best of luck
