[$injector:unpr] Unknown provider: dataProvider <- data

[Deva Anand]

I am trying to write some unit test for my app, but I am running into an issue.

My .js file looks like

function () {
angular.module('app',[])
    .factory('code', function ($http, svc, $q) {

         function getCodeByID(id) {
            return $http.get(svc.get('my-application') + id)
                .then(function (res) {
                    return res;
                });
        }

    function getCodes(query) {
        var qry = ccUtils.buildQuery(query);
        return $http.get(svc.get('url')
            .then(function (response) {
                var resObj = {};
                resObj.data = response.data.content;
                resObj.pageData = {
                    totalPages: response.data.totalPages,
                    totalElements: response.data.totalElements
                };
                return resObj;
            }));
    }
        });
})();

My spec.js file looks like.

describe('MyController', function() {
var data, svc, code;

// Set up the module
//beforeEach(module('app'));
beforeEach(angular.mock.module('app'));

beforeEach(inject(function(_data_) {
    data = _data_;
}));

beforeEach(inject(function(_svc_) {
    svc = _svc_;
}));

beforeEach(inject(function(_code_) {
    code = _code_;
}));

it('Should exist', function() {
    expect(code).toBeDefined();
});

});

MyController
× Should exist
