按照angularJS $ httpBackend的官方指南,我会做这个测试,但是Karma给我这个错误: Error: No pending request to flush ! at Function.$httpBackend.flush

测试

'use strict';

describe('profileCtrl', function () {
var scope, $httpBackend;

beforeEach(angular.mock.module('maap'));
beforeEach(angular.mock.inject(function($rootScope, $controller, _$httpBackend_){

    $httpBackend = _$httpBackend_;
    $httpBackend.when('GET', 'profile').respond([{id: 1, name: 'Bob'}]);
    scope = $rootScope.$new();
    $controller('profileCtrl', {$scope: scope});
}))

it('should fetch list of users', function(){
    $httpBackend.flush();
    expectGET(scope.current_user.length).toBe(1);
    expect(scope.current_user[0].name).toBe('Bob');
});

});

这个简单的控制器:

'use strict';

 angular.module('maap').controller('profileCtrl', function($scope, UserService) {

$scope.current_user = UserService.details(0);

});

我有3个服务返回3个promise,但第三个需要第二个数据,所以我把它称为第二个.我想等待所有三个承诺得到解决,这是我实现的方式,但不起作用(仅等待第一个和第二个).

var promise1, promise2, promise3;

promise1 = service1();
promise2 = service2();

promise2.then(function (data) {
  promise3= service3(data);

});

$q.all([ promise1, promise2, promise3]).then(function success() {
 //somehing
});

我尝试将我的应用程序部署到heroku服务中,但在推送文件后,日志会给我这个错误:错误:大多数中间件(如logger)不再与Express捆绑在一起,必须单独安装.
