我正在使用茉莉花进行angularJS测试。在我的观点中,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");
});
});
调用scope.status
肯定会以错误结束:
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“controller as”语法。具体做法是:
$ controller(' configCtrl as config ',{$ scope:scope});
期望(的 scope.config.status 强>)砥( “任何”);
以下内容现在应该通过:
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");
});
});
