karma/angularjs如何使用服务测试运行块

这篇文章如下 我已经发布了另一个更简单的帖子 范例

要测试的代码 测试 这给了我这个错误

**Error: Unexpected request: GET menus.json
No more request expected**

最后请看@scarIz的回复

---

出现错误的原因是，

菜单.query

将在您对

myApp

模块执行每个测试之前运行，因为它在模块的

.run（）

配置中被调用。虽然您已经在

运行测试套件中提供了后端定义，但您还没有为
MainCtrl
提供后端定义

因此，为了解决这一问题，您可能希望使用在每次测试之前运行的全局
beforeach
块，该块应在规范之前包含的帮助文件中定义：

beforeEach(inject(function($httpBackend) {
  $httpBackend.when('GET', 'menus.json').respond([{id: 1, name: 'Bob'}])
  $httpBackend.flush();
}));

@斯卡尔兹非常感谢：）很抱歉打扰你，你能看一看测试结果吗？我应用了相同的代码，但在ui路由器上它不工作，我想知道如何修复它^^
**Error: Unexpected request: GET menus.json

beforeEach(module('myApp'));
var $httpBackend;
beforeEach(inject(function( _$httpBackend_) {
    $httpBackend = _$httpBackend_;

        id: 1, 
        name: 'Bob'
    }])

afterEach(function() {
    $httpBackend.verifyNoOutstandingExpectation();
    $httpBackend.verifyNoOutstandingRequest();
});

        //mock Application to allow us to inject our own dependencies

        //mock the controller for the same reason and include $rootScope and $controller
        beforeEach(inject(function( $controller,_$rootScope_, _$httpBackend_){
