問題描述

我正在用一個小型 AngularJS 應用程序測試 Protractor.

I'm testing Protractor with a small AngularJS app.

這是測試:

describe('Testing Protractor', function() {
  var draftList;

  it('should count the number of drafts', function() {
    browser.get('#/');
    draftList = element.all(by.repeater('newsletter in drafts'));
    expect(draftList.count()).toEqual(2);
  });
});

控制器:

angular.module('myApp.controllers', []).
  controller('DraftsCtrl', ['$scope', 'Draft', function($scope, Draft) {
    $scope.drafts = Draft.query();
}])

草稿服務:

angular.module('myApp.services', ['ngResource']).
  factory('Draft', ['$resource',
    function($resource) {
      return $resource('api/drafts/:id')
    }])

使用 Protractor 運行此測試會導致以下錯誤:

Running this test using Protractor results in the following error:

Error: Timed out waiting for Protractor to synchronize with the page after 11 seconds

但是，如果在控制器中我更改此行:

However, if in the controller I change this line:

$scope.drafts = Draft.query();

到這里:

$scope.drafts = [];

測試按預期失敗，但更重要的是:它不會超時.

The test fails as expected, but more importantly: it does not time out.

啟用 query() 后，無論是在瀏覽器中手動運行應用程序，還是查看 Protractor 打開的瀏覽器窗口時，API 返回的數據都會由中繼器正確顯示.

With query() enabled, both when running the app manually in a browser and when looking at the browser window opened by Protractor, the data returned by the API is correctly displayed by a repeater.

為什么服務與 API 通信時 Protractor 無法與頁面同步?

Why is Protractor not able to synchronize with the page when the service is communicating with the API?

AngularJS 是 v1.2.0-rc3.量角器是 v0.12.0.

AngularJS is v1.2.0-rc3. Protractor is v0.12.0.

推薦答案

這是一個已知問題，但是有一個臨時的解決方法.設置 ptor.ignoreSynchronization = true.

This is a known issue, but there is a temporary workaround. Set ptor.ignoreSynchronization = true.

例如:

describe('Testing Protractor', function() {
  var draftList;
  var ptor;

  beforeEach(function() {
    ptor = protractor.getInstance();
    ptor.ignoreSynchronization = true;
  });

  it('should count the number of drafts', function() {
    ptor.get('#/');
    draftList = element.all(by.repeater('newsletter in drafts'));
    expect(draftList.count()).toEqual(2);
  });
});
