Question

Click Here for the Screenshot------I am getting this error "Error: beforeEach expects a function argument; received [object Object]" while testing angularjs using karma and jasmine.I have tried in so many ways but couldn't get the solution. I have given below my spec code and karma conf js . for your information i do use requirejs in my application due to some dependencies

//Service Spec code :

define([], function () {
'use strict';
describe('search Service spec', function () {
    var searchService;

    beforeEach(angular.module('flightRouteApp', []));

    describe('service methods', function () {

            it('should calculate the length of the element', inject(function (searchService) {
                expect(searchService).toBeDefined();
            }));
     });
});

}）;

只需更改您的beforeEach，即可：

beforeEach(module('flightRouteApp'));

得到此错误“错误：beforeEach期望一个函数参数;收到[object Object]”，同时使用karma和jasmine测试angularjs
