如何在Jasmine中使用带有"Controller as"语法的范围变量？

Question

我正在使用茉莉花进行angularJS测试.在我的视图中,我使用"Controller as"语法:

<div ng-controller="configCtrl as config">
    <div> {{ config.status }} </div>
</div>

如何在茉莉花中使用这些"范围"变量？"控制器"指的是什么？我的测试如下:

describe('ConfigCtrl', function(){
    var scope;

    beforeEach(angular.mock.module('busybee'));
    beforeEach(angular.mock.inject(function($rootScope){
        scope = $rootScope.$new();

        $controller('configCtrl', {$scope: scope});
    }));

    it('should have text = "any"', function(){
        expect(scope.status).toBe("any");
    });
}); 

默认情况下scope.status,调用结束时会出现错误:

Expected undefined to be "any".

更新:控制器(从TypeScript编译的javascript)如下所示:

var ConfigCtrl = (function () {
    function ConfigCtrl($scope) {
        this.status = "any";
    }
    ConfigCtrl.$inject = ['$scope'];
    return ConfigCtrl;
})();

解决方案是在测试中实例化控制器时使用"控制器为"语法.特别:

$ controller(' configCtrl as config ',{$ scope:scope});

expect(scope.config.status).toBe("any");

现在应该通过以下内容:

describe('ConfigCtrl', function(){
    var scope;

    beforeEach(angular.mock.module('busybee'));
    beforeEach(angular.mock.inject(function($controller,$rootScope){
        scope = $rootScope.$new();

        $controller('configCtrl as config', {$scope: scope});
    }));

    it('should have text = "any"', function(){
        expect(scope.config.status).toBe("any");
    });
});

当我们使用controller as语法时,不需要将$ rootScope注入我们的测试中.以下应该可以正常工作.

describe('ConfigCtrl', function(){
    beforeEach(module('busybee'));

    var ctrl;

    beforeEach(inject(function($controller){
        ctrl = $controller('ConfigCtrl');
    }));

    it('should have text = "any"', function(){
         expect(ctrl.status).toBe("any");
    });
});
