JavaScript - AngularJS promise 不返回任何东西

Question

我正在尝试使用 Jasmine 返回关于单元测试的简单 HTTP 帖子，但它似乎不起作用。该应用程序在网络上运行良好。我测试了几个孤立的功能。但这行不通。

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

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

    var AuthFactory, httpBackend;

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

    it('should return POST', function() {
        AuthFactory.signIn({inputUser: {username: "admin"}, passInput: {password: "adminpass"}}).then(
            function(result) {
                console.log('======== SUCCESS ========');
                console.log(result);
            },
            function(err) {
                console.log('======== ERROR ========');
                console.log(err);
            },
            function(progress) {
                console.log('======== PROGRESS ========');
                console.log(progress);
            }
        );
        console.log('HTTP call finished.');
        expect(1).toBe(1);
    });

});

这是工厂:

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

    var AuthFactory = {};

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

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

    return AuthFactory;

}]);

这是我得到的:

PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 0 of 1 SUCCESS (0 s
LOG: Object{$$state: Object{status: 0}, success: function (fn)
{ ... }, error: function (fn) { ... }}
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 0 of 1 SUCCESS (0 s
LOG: 'HTTP call finished.'
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 0 of 1 SUCCESS (0 s
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 1 of 1 SUCCESS (0 s
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 1 of 1 SUCCESS (0 secs / 0.022 secs)

我已经通过 Postman 测试了 HTTP 调用，它成功返回了数据。那么...我做错了什么？

谢谢。

AuthFactory.signIn 是异步的并返回一个 promise - 您的测试函数在 promise 得到解决之前完成。

你需要告诉 Jasmine 它应该 wait for the asynchronous test to complete :

it('should return POST', function(done) {
  var result = AuthFactory.signIn({inputUser: {username: "admin"}, passInput: {password: "adminpass"}}).then(
      function(result) {
          console.log('======== SUCCESS ========');
          console.log(result);
      },
      function(err) {
          console.log('======== ERROR ========');
          console.log(err);
      },
      function(progress) {
          console.log('======== PROGRESS ========');
          console.log(progress);
      }
  );
  result.then(function(){
    console.log('HTTP call finished.');
    expect(1).toBe(1);
  }).finally(done); //here we hook Jasmine callback to promise chain
});
