参见这里例如:

正如标题所示,我遵循本教程[http://tech.pro/tutorial/1473/getting-started-with-angularjs-unit-testing]设置单元测试,一切都很好,除了事实,我似乎不能访问vm变量作为我的$范围。
仪表板
var controllerId = 'dashboard'; angular.module('app') .controller(controllerId,['common','datacontext',dashboard]); function dashboard(common,datacontext) { var getLogFn = common.logger.getLogFn; var log = getLogFn(controllerId); var vm = this; vm.title = 'Dashboard';
dashboard.Spec.js
describe("app module",function() { beforeEach(module("app")); describe("dashboard",function() { var scope,controller; beforeEach(inject(function($rootScope,$controller) { scope = $rootScope.$new(); controller = $controller; })); it("should assign Dashboard as title",function() { controller("dashboard",{ $scope: scope }); expect(scope.title).toBe("Dashboard"); }); }); });
我试过的:它工作(测试通过),当我命名’$ scope’直接在控制器依赖和设置“title”属性。但是,我想保持这个模式。
我还尝试直接在依赖关系中传递$ scope,并将控制器参数命名为“vm”…
Karmas失败的测试消息是:预期未定义为“Dashboard”
欣赏任何帮助!
啊,显然现在…我可以通过引用在测试中创建的控制器访问vm变量:
it("should assign Dashboard as title",function () { var vm = controller("dashboard",{ $scope: scope }); expect(vm.title).toBe("Dashboard"); });
