单元测试组件角

Question

我想单元测试我的组件控制器，我得到以下错误。谁能告诉我，这里有什么不对？

我的依赖关系：

• 角1.5.6
• 角嘲笑1.5.7
• 摩卡2.5.3
• 因缘0.13.22

错误：

modalCleanup component "before all" hook: workFn FAILED 
    Error: [$injector:unpr] Unknown provider: $elementProvider <- $element

组件：

"use strict"; 

import template from "./template.html"; 
import "./style.styl"; 

export default { 
template: template, 
controller: function(MailboxesApi, ErrorHandler, MailboxesStore, Notify, LettersStore, $element, $state, $rootScope) { 
    "ngInject"; 

Object.defineProperty(this, "removing", { 
    get: function() { 
    return MailboxesApi.removing; 
    } 
}); 

$rootScope.$on("modal.cleanup.open",() => this.open()); 

this.close =() => { 
    $element.removeClass("w-cleanup_opened"); 
    $element.off("click"); 
}; 

this.open =() => { 
    $element.addClass("w-cleanup_opened"); 
    $element.on("click",() => this.close()); 
}; 

this.preventBubbling = e => e.stopPropagation(); 

this.confirmHandler =() => { 
    let selected = MailboxesStore.selected; 

    MailboxesApi.cleanup(selected) 
    .then(() => { 

     LettersStore.deselectAll(); 
     LettersStore.removeAll(selected); 
     this.close(); 
     Notify.add("The mailbox was successfully cleaned!"); 
     $state.reload(); 

    }, err => { 
     this.close(); 

     ErrorHandler.handle(err); 
    }); 
}; 

} 
}; 

测试：

"use strict"; 

describe("modalCleanup component", function() { 
let modalCleanupController, $componentController; 

angular.mock.module.sharedInjector(); 

before(angular.mock.module("app")); 

before(angular.mock.module(function($urlRouterProvider) { 
    $urlRouterProvider.deferIntercept(); 
})); 

before(angular.mock.inject(function(_$componentController_) { 
    $componentController = _$componentController_; 
modalCleanupController = $componentController("modalCleanup", null); 
    })); 

it("test...", function() {}); 

});

您需要提供$ componentController因为你在控制器中定义使用它功能$元素。 你可以在你的单元测试中定义类似smtg：

var element = angular.element('<button></button>'); 
modalCleanupController = $componentController("modalCleanup", { 
    //create an empty scope 
    $scope: {}, 
    $element: element 
});
