按照
angularJS $httpBackend的官方指南，我会做这个测试，但是Karma给我这个错误：
错误：无待处理的请求冲洗！
在函数$ httpBackend.flush
错误：无待处理的请求冲洗！
在函数$ 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(){
$httpBackend.flush();
expectGET(scope.current_user.length).toBe(1);
expect(scope.current_user[0].name).toBe('Bob');
});
});
对于这个简单的控制器：
'use strict';
angular.module('maap').controller('profileCtrl',function($scope,UserService) {
$scope.current_user = UserService.details(0);
});
_ $ httpBackend_无法刷新，因为您的测试中没有发出任何http请求。
原文链接：https://www.f2er.com/angularjs/144067.html然后，一旦某个地方在您的测试中发出http请求，您可以调用flush方法，以便为已经创建的请求提供响应。
就像是：
it('should fetch list of users',function(){
// Do something that will make an http request
MyService.getAllUser(function ...) // for example
// Then provide a response for the http request that
// has been made when getAllUser was called
$httpBackend.flush();
// Check the expected result.
expect(something).toBe('Bob');
});
