EmberJS 測試路由

2018-01-03 17:03 更新

測試路由

您可以使用兩種方法測試路由。一個是接受，另一個是單元測試。驗收測試通常用于測試應(yīng)用程序的工作流，單元測試通常用于測試一小段代碼。

例子

         <script type="text/javascript">
            //Creates an instance of Ember.Application and assign it to a global variable
            App = Ember.Application.create();

            //The 'map' method can be invoked to define URL mappings
           App.Router.map(function() {
             this.route('home');
           });

           //Customize the behavior of a route by creating an Ember.Route subclass
          App.ApplicationRoute = Ember.Route.extend({
              _displayText: function(navtext) {

          //The IndexController template stores its properties and sends its actions to the Controller
          App.IndexController = Ember.Controller.extend({

          });

          //emq.globalize();

          //The 'DefaultResolver' defines the default lookup rules before consulting the container for registered items
          setResolver(Ember.DefaultResolver.create({ namespace: App }));
          App.setupForTesting();   //This method is used to prepare the application for testing

          var res;

          //The 'moduleFor' helper is used to setup a test container
          moduleFor('route:application', 'Unit: route/application', {
             setup: function() {
                res = window.document.write;   //Store a reference to the browser
             },
            teardown: function() {
              window.document.write = res;   //Restore original functions
            }
          });

          test('Display is called on displayText', function() {

          //'this.subject()' is used to get an instance of the 'IndexController' and 'HomeController'
          var route = this.subject();

          //The text to be display
          var expectedText = 'Tutorialspoint';

          //Defines window.document.write to perform a qunit test
          window.document.write = function(navtext) {
             equal(navtext, expectedText, 'expected ' + navtext + ' to ' + expectedText);
          }

          //Call the _displayText function which triggers the qunit test above
          route._displayText(expectedText);
        });

輸出

讓我們執(zhí)行以下步驟，看看上面的代碼如何工作：

將上面的代碼保存在testing_routes.html文件中
在瀏覽器中打開此HTML文件。

以上內(nèi)容是否對您有幫助：
