AngularJs应用程序的量角器定位器超时异常 [英] Protractor Locator Time Out exception for AngularJs application

问题描述

我们正在尝试使可公开访问的网站自动化，并单击其中一个链接，但是在定位元素时，测试失败并显示TimeOut Exception:

来自:任务:Protractor.waitForAngular()-定位器:作者(链接文本，我的帐户)下面的示例conf和spec文件.请求有关如何解决此问题的帮助.

conf.js

  exports.config = {seleniumAddress:'http://localhost:4444/wd/hub'，功能:{'browserName':'chrome'}，规格:['test.js']};test.jsdescribe('test'，function(){它(应该导航"，功能(完成){browser.get('https://ww2.tracfone.com');element(by.linkText('MY ACCOUNT')).click();完毕();});}; 

解决方案

找到了您在网页中看到的问题的根本原因.看来您的网站持续轮询$ timeout或$ http，Protractor将无限期等待并超时.

我已经监视了下面的http流量，发现您的应用程序频繁轮询，而Protractor只是在等待.检出下面的屏幕抓取.(时间轴中的绿色标记表示$ http呼叫--

有关为什么会出现此错误的更多详细信息，请参见此处

Interval.js :我不是这方面的专家，但是您可以探索更多这里

对于连续轮询的任何事物，都应使用$ interval(在Angular 1.2rc3中引入).

3. 尝试使用不同的timeout配置，看看一段时间后您的应用程序轮询是否停止

   allScriptsTimeout:120000，getPageTimeout:120000，jasmineNodeOpts:{defaultTimeoutInterval:120000}

We are trying to automate a publicly accessible website and click on one of the links, but the test fails with TimeOut Exception while locating the element as below:

From: Task: Protractor.waitForAngular() - Locator: By(link text, MY ACCOUNT) Sample conf and spec file below. Requesting help on how to solve this issue.

conf.js

exports.config = {
                seleniumAddress: 'http://localhost:4444/wd/hub',
                capabilities: {
                                'browserName': 'chrome'
                },             
                specs: ['test.js']
};

test.js

describe('test', function() {

                it('should navigate', function(done) {
                                browser.get('https://ww2.tracfone.com');
                                element(by.linkText('MY ACCOUNT')).click();
                                done();
                });
};

解决方案

Found the root cause for the issue you were seeing for your webPage. Looks like your site continuously polls $timeout or $http, Protractor will wait indefinitely and time out.

I have monitored the http traffic below and see that your app polls at frequent intervals and Protractor just waits. Checkout the screen grab below.(The green marks in the timeline indicating $http calls to - https://ww2.tracfone.com/cgi-bin/tealeaf.pl )

More details on why you are seeing this error is documented here. ok. Coming to the different solutions for this, there are multiple work-arounds for this. I will just talk in brief about the alternatives and leave it to you to choose the best one.

1. IgnoreSynchronization: Turn this flag - browser.ignoreSynchronization to false before the browser.get() and continue with the test flow and set the flag to true again for other pages Check here

2. Interval.js : I am no expert on this but you can explore more here

You should use the $interval for anything that polls continuously (introduced in Angular 1.2rc3).

3. Try with different timeOut configurations and see if your app polling stops after some time

   allScriptsTimeout: 120000, getPageTimeout: 120000, jasmineNodeOpts: { defaultTimeoutInterval: 120000 }
