本文介绍了测试以$资源响应执行服务控制器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个使用服务控制器,解决一个承诺,然后设置一个变量。
我想测试,如果变量已定,我怎么做呢?

Service.js

 
.module(MyModule的')
。服务('为MyService',['$资源',函数($资源){
  变种R = $资源('/用户/:身份证',{ID:@ ID'});
  this.post =功能(_user){
      返程(新R(_user))。$保存()
   }
}])

控制器

 
.module(MyModule的')
.controller('myCtrl',['为MyService,功能(为MyService){
  VAR VM =这一点;
  vm.value = 0;
  vm.post =功能(_user){      MyService.post(_user)。然后(函数(){
        vm.value = 1;
      });
  };
}])

controller_spec

 描述(测试控制器,函数(){
  beforeEach(模块('Mymodule中'));
  beforeEach(注入(函数($控制器,为MyService){
    this.ctrl = $控制器('myCtrl');
  }))  它('后保存值是1,函数(){
    this.ctrl.post({名称:'盘'});    //始终this.ctrl.value它等于0
    期待(this.ctrl.value).toBeEqual(1);
  });});


解决方案

嘲笑服务方法,并返回一个承诺,那么解决它,当你需要它。

 描述(测试控制器,函数(){
  VAR postDefer;
  beforeEach(模块('Mymodule中'));
  beforeEach(注(函数($控制器,为MyService,$ Q){
    postDefer = $ .defer();
    spyOn(为MyService,'后')and.returnValue(postDefer.promise)。
    this.ctrl = $控制器('myCtrl',{为MyService:为MyService});
  }))  它('后保存值是1,函数(){
    this.ctrl.post({名称:'盘'});    postDefer.resolve();    。范围$适用();
    期待(this.ctrl.value).toBeEqual(1);
  });});

I have a controller that use a service, resolve a promise and then set a variable.I want to test if the variable has been set, How I do this?

Service.js

angular
.module('myModule')
.service('MyService',['$resource',function($resource){
  var r =  $resource('/users/:id',{id:'@id'});
  this.post = function(_user){
      return (new r(_user)).$save()
   }
}])

Controller

angular
.module('myModule')
.controller('myCtrl', ['MyService',function(MyService){
  var vm = this;
  vm.value = 0;
  vm.post = function(_user){

      MyService.post(_user).then(function(){
        vm.value = 1;
      });
  };


}])

controller_spec

describe('Test Controller',function(){
  beforeEach(module('myModule'));
  beforeEach(inject(function($controller, MyService){
    this.ctrl = $controller('myCtrl');
  }))

  it('after save value is 1',function(){
    this.ctrl.post({name: 'chuck'});

    //Always this.ctrl.value it's equal to 0
    expect(this.ctrl.value).toBeEqual(1);
  });

});
解决方案

mock the service method and return a promise, then resolve it when you need it.

describe('Test Controller',function(){
  var postDefer;
  beforeEach(module('myModule'));
  beforeEach(inject(function($controller, MyService, $q){
    postDefer = $.defer();
    spyOn(MyService, 'post').and.returnValue(postDefer.promise);
    this.ctrl = $controller('myCtrl', {MyService : MyService});
  }))

  it('after save value is 1',function(){
    this.ctrl.post({name: 'chuck'});

    postDefer.resolve();

    scope.$apply();
    expect(this.ctrl.value).toBeEqual(1);
  });

});
