角单元测试未知提供商：$ scopeProvider

问题描述

您好，我写我的茉莉第一角度测试，但我不断收到错误

------测试开始：文件：C：\\用户\\里根\\文档\\的Visual Studio 2013 \\网站已\\里根\\ testApp \\ TestProject \\ NG-测试\\ MainCtrlSpec.js ------
测试MainCtrl与内嵌模拟：应该有标贴'失败
    错误：[$喷油器：unpr]未知提供商：$ scopeProvider＆LT; - $范围＆LT; - MainCtrl

我试图玩弄它，但我卡住了。如果你看到问题，请让我知道。如果您需要更多code，以及请让我知道，但我认为这个问题是在这两个文件。

MainCtrl.js

  VAR应用= angular.module（ChartApp，[chart.js之]）;    app.controller（MainCtrl，[$范围
      功能（$范围，DataSrv）{
          $ scope.labels = DataSrv.labels;
          $ scope.data = DataSrv.data;
          $ scope.type = DataSrv.type;
          $ scope.title = DataSrv.title;
      }
    ]）;
 

解决方案

由于没有 $范围服务， $控制器提供商不能实例注入 $范围参数。

您需要提供范围在实例中使用 $控制器供应商的控制器。你可以注入 $ rootScope 在你的设置，你可以通过做得到一个子作用域 $ rootScope。$新的（） 。注入它作为参数传递给 $控制器 contstructor。即 $控制器（MainCtrl，{$范围：适用范围}），其中范围的，甚至你可以在$ rootScope

通过新的子范围。

即

  VAR CTRL，mockDataSrv，范围;
    // ...您code
    // ...
    beforeEach（注（函数（$控制器，$ rootScope）{
        范围= $ rootScope $新的（）。 //得到childscope
        CTRL = $控制器（MainCtrl，{$范围：适用范围}）; //把它作为参数作为$范围的价值
    }））;
 

Hello I am writing my first angular test with Jasmine but I keep getting the error

------ Test started: File: C:\Users\Regan\Documents\Visual Studio 2013\WebSites\Regan\testApp\TestProject\ng-tests\MainCtrlSpec.js ------Test 'MainCtrl with inline mock:should have lables' failed Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope <- MainCtrl

I have tried playing around with it but am stuck. If you see the problem please let me know. If you need more code as well please let me know but I think the problem is in these two files.

    beforeEach(module("ChartApp"));

    var ctrl, mockDataSrv;

    beforeEach(module(function($provide) {
        mockDataSrv = {
            labels: ["Reading", "Coding", "Thinking About Coding", "Reddit", "StackOverflow"],
            data: [500, 300, 300, 40, 220],
            type: "PolarArea",
            title: "Angular Chart Expriment"
        };
        $provide.value("DataSrv", mockDataSrv);
    }));

    beforeEach(inject(function ($controller) {
        ctrl = $controller("MainCtrl");
    }));

    it("should have lables", function () {
        expect(scope.labels).toBeDefined();
    });
});

MainCtrl.js

var app = angular.module("ChartApp", ["chart.js"]);

    app.controller("MainCtrl", ["$scope",
      function ($scope, DataSrv) {
          $scope.labels = DataSrv.labels;
          $scope.data = DataSrv.data;
          $scope.type = DataSrv.type;
          $scope.title = DataSrv.title;
      }
    ]);

解决方案

Since there is no $scope service, $controller provider cannot instantiate the injected $scope argument.

You need to provide the scope while instantiating a controller using the $controller provider. You can inject $rootScope in your setUp and you can get a child scope by doing $rootScope.$new(). Inject it as an argument to the $controller contstructor. i.e $controller("MainCtrl", {$scope:scope }) where scope is the new child scope of even you can pass in the $rootScope.

i.e

   var ctrl, mockDataSrv, scope;
    //... Your code
    //...
    beforeEach(inject(function ($controller, $rootScope) {
        scope = $rootScope.$new(); //get a childscope
        ctrl = $controller("MainCtrl", {$scope:scope }); //Pass it as argument as $scope's value
    }));
