The error message states, "undefined cannot be used as a function."

For testing purposes, I am running checks on my Service using httpBackend. Specifically, I am focusing on a simple get request that needs to be tested for the response code. However, despite my efforts, I keep encountering this error:

TypeError: undefined is not a function (evaluating '$httpBackend.expectGET('/api/something').response({})') in test/spec/services/requests.js (line 22)
        test/spec/services/requests.js:22:51
        Error: Unsatisfied requests: GET /api/something in /bower_components/angular-mocks/angular-mocks.js (line 1812)
        verifyNoOutstandingExpectation@/bower_components/angular-mocks/angular-mocks.js:1812:74
        /test/spec/services/requests.js:28:48

This is the service setup:

angular.module('requestService', [])
  .factory('Request', ['$http', 'localConfig', 'Query', function($http, localConfig){
return {
      getRequest: function(fromDate, toDate) {
        return $http({
          url: '/api/something',
          method: "GET",
          params: {fromDate: fromDate,
                    toDate: toDate},
          headers: {
            'Content-Type': 'application/json; charset=utf-8'
          }
        })
      }
     }
  }]);

This is how the testing process is structured:

describe('Service: Request', function () {
  var reqService, $httpBackend;
  beforeEach(module('webapp'));
  beforeEach(module('requestService'));
  beforeEach(inject(function(Request, _$httpBackend_){
    reqService = Request;
    $httpBackend = _$httpBackend_;
  }));

  it('should test the response to be 200', function(){
    $httpBackend.expectGET('/api/something').response({});
    $httpBackend.flush();
  });

  afterEach(function(){
    $httpBackend.verifyNoOutstandingExpectation();
    $httpBackend.verifyNoOutstandingRequest();
  })
});

EDIT

Following recommendations, changes were made to the test:

it('should test the response to be 200', function(){
    console.log('service: ' + reqService);
    reqService.getRequest('2016-03-26', '2016-03-29');
    $httpBackend.expectGET('/api/something').respond({});
    $httpBackend.flush();
  });

Unfortunately, a new issue has arisen:

 Error: Unexpected request: GET /api/something?fromDate=2016-03-26&toDate=2016-03-29

Answer №1

You forgot to invoke the getRequest function in the service, which means the ajax call was never made. This is why the expectGET condition was not satisfied and resulted in an Error: Unsatisfied requests:. Additionally, there is a typo where response should be corrected to respond.

it('should verify that the response is 200', function(){
    //performing the action
    reqService.getRequest();

    $httpBackend.expectGET('/api/something').respond({});
    $httpBackend.flush();
});

Answer №2

It appears that the correct method to use is respond() instead of response():

$httpBackend.expectGET('/api/something').respond({});
