使用Jasmine测试服务功能POST响应 [英] Testing a service function POST response with Jasmine

问题描述

我不完全确定如何执行此操作，但我有一个端点URL，它是登录身份验证的POST请求。添加请求有效内容时，您将获得成功的登录凭据或错误。但是，我似乎在获取回复方面遇到了问题。

I'm not entirely sure how to do this but I have a endpoint URL which is a POST request for login authentication. When you add a request payload, you will get either a successful login credential or an error. However, I seem to have problems with fetching the response.

这是我的规范文件：

describe('Service: AuthFactory',function(){

    beforeEach(function () {
        module('ui.router');
        module('users');
        module('main');
    });

    var AuthFactory, httpBackend;

    beforeEach(inject(function($httpBackend, $rootScope, $controller, _AuthFactory_){
        httpBackend = $httpBackend;
        AuthFactory = _AuthFactory_;

    }));

    it('Return a POST response from a Service function', function() {
        var url = "http://localhost:3000";
        var dataObj = JSON.stringify({
            inputUser: { user: "TestCase1" },
            inputPass: { password: "TestPass1" }
        });
        httpBackend.expect('POST', url + '/api/AuthService/signIn', dataObj)
            .respond({});

        AuthFactory.signIn(dataObj).success(function(response) {
            console.log(response);
            // outputs Object {}
            // when in reality it should
            // output the response to POST
            // eg: { "login": { "user": "Test_User", "time": 54935934593 }, "outputHead": { "token": asjfjj234kfAd } }
        });

        httpBackend.flush();

        expect(true).toBe(true);
    });
});

这是我的服务。

angular.module('users').factory('AuthFactory', ['$http', function($http) {

var AuthFactory = {};

AuthFactory.signIn = function(data) {
    return $http.post('http://127.0.0.1:3000/api/AuthService/signIn', data);
};

AuthFactory.signOut = function(data) {
    return $http.post('http://127.0.0.1:3000/api/AuthService/signOut', data);
};

return AuthFactory;

}]);

当我运行测试时，它（显然）通过了控制台。 log（）输出对象{} 。

When I run the test, it passes (obviously) but the console.log() outputs Object{}.

当我使用Chrome扩展程序时像邮差。我做一个示例POST请求，返回的响应是登录凭据！那么为什么它适用于Postman而不是我的 AngularJS Jasmine单元测试？

And when I use a Chrome extension like Postman. I do an example POST request and the response that returns is the login credentials! So why is it working on Postman but not on my AngularJS Jasmine unit test?

推荐答案

这一行就是你得到一个空对象作为回应的原因：

This line is why you get an empty object as your response:

httpBackend.expect('POST', url + '/api/AuthService/signIn', dataObj)
        .respond({});

要给出您想要的回复，只需添加以下内容：

To give the response you want just add the following:

httpBackend.expect('POST', url + '/api/AuthService/signIn', dataObj)
            .respond({"login": { "user": "Test_User", "time": 54935934593 }, "outputHead": { "token": asjfjj234kfAd }});
