没有关于量角器browser.actions()和抛出TypeError的默认建议:browser.actions(.).dragAndDrop(.).perfrom不是函数

Question

我正在使用window 10 OS中5.4.2版本的量角器版本，为了编写脚本，我使用Eclipse进行网络Developers.Version:光子发布(4.8.0)和Tern插件。

对于browser.actions()我没有默认的建议。另外，由于以下错误，我的执行失败了。

消息:失败:browser.actions(.).dragAndDrop(.).perfrom不是函数堆栈: TypeError: browser.actions(.).dragAndDrop(.).perfrom不是UserContext的函数。(F:\Learning\Repositories\protractor-sam-test-scripts\EclipsePro\src\com\sam\scriptjs\draganddrop.spec.js:15:45) at C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\jasminewd2\index.js:112:25 at new ManagedPromise (C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\promise.js:1077:7)(C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\promise.js:2505:12) at schedulerExecute (C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\jasminewd2\index.js:95:18) at TaskQueue.execute_ (C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\promise.js:3084:14) at TaskQueue.executeNext_ (C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\promise.js:3067:27) at asyncRun (C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\promise.js:2974:25) at C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\lib\promise.js:668:7 at From: Task:在UserContext的控制流中运行它(“拖放”)。来自异步测试的(C:\Users\sam\AppData\Roaming\npm\node_modules\protractor\node_modules\jasminewd2\index.js:94:19)：Suite的错误。(F:\Learning\Repositories\protractor-sam-test-scripts\EclipsePro\src\com\sam\scriptjs\draganddrop.spec.js:11:4) at Object.(F:\Learning\Repositories\protractor-sam-test-scripts\EclipsePro\src\com\sam\scriptjs\draganddrop.spec.js:2:1) at Module._compile (module.js:652:30) at Object.Module._extensions..js (module.js:663:10) at Module.load (module.js:565:32) at tryModuleLoad (module.js:505:12)

我已经更新了我的protractor和webdriver-manager版本，但是错误仍然存在。

请看我的spec.js

//draganddrop.spec.js
describe('drag and drop trial', function() {


      //Each single it function is a test script
      it('first spec', function() {
          browser.driver.get('https://codef0rmer.github.io/angular-dragdrop/#!/');
        expect(browser.getTitle()).toEqual('Drag and Drop for AngularJS');
      });

      it('Drag and drop', function() {
           var from=element(by.model('list1'));
           var to=element(by.model('list2'));
          //drag and drop source  to Destination
           browser.actions().dragAndDrop(from,to).perfrom();
           browser.sleep(7500);
          });

}) 

Answer 1

尝试使用以下代码：

    //1st way: dragging one element to another
    browser.actions().mouseDown(from).mouseMove(to).mouseUp().perform();

在实现dragAndDrop的三种方法中，我发现这种方法在量角器中是最合适的。
