量角器 browser.get() 在 IE11 中抛出异常答案

【问题标题】：Protractor browser.get() throwing exception in IE11量角器 browser.get() 在 IE11 中抛出异常
【发布时间】：2019-12-18 15:04:03
【问题描述】：

我正在尝试在 Win 8.1 上的 IE11 中运行一个简单的量角器测试。

我的测试：

it("should navigate to from the homepage to the add contact page", function () {
    browser.get("http://localhost:4000/");
    // ... it already crashes here
});

我的配置：

exports.config = {
// run in multiple browsers
multiCapabilities:[    
    {
       'browserName': 'internet explorer',
    }
],

specs: ['./**/*js'],

// Options to be passed to Jasmine-node.
jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000
},

onPrepare: function () {
    require('jasmine-reporters');
    jasmine.getEnv().addReporter(
        new jasmine.JUnitXmlReporter('xmloutput', true, true)
    );
}
};

错误：

我对量角器还是很陌生，我不知道该怎么做。我的测试在 Chrome 和 Firefox 中运行良好。有什么想法吗？

【问题讨论】：

您要测试的是 Angular 应用吗？如果在量角器配置中添加allScriptsTimeout: 300000, 会怎样？如果你打开browser.get("https://angularjs.org/"); - 同样的错误怎么办？谢谢。
您是否尝试对 chrome 运行测试以排除它是 IE 驱动程序问题？

【解决方案1】：

试试这个，对我来说它有助于解决类似的错误A Jasmine spec timed out. Resetting the WebDriver Control Flow.

量角器-conf.js

{"browserName": "internet explorer",
    "ie.forceCreateProcessApi": true,
    "ie.browserCommandLineSwitches": "-private",
    "ie.ensureCleanSession": "true",
    "seleniumAddress": 'http://10.0.1.XXX:4444/wd/hub'
}

确保设置了路径 HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main 中的 TabProcGrowth" = dword: 00000000。

【解决方案2】：

IEExplorerDriver 有望实现异步脚本执行，但存在几个已知问题，即驱动程序可能会很慢并且经常超时等待页面加载：

http://angular.github.io/protractor/#/browser-setup

https://github.com/angular/protractor/issues/1052

根据您提供的日志，这些行以某种方式表明发生了超时。

对于 Protactor 团队来说，这仍然是一个悬而未决的问题，希望他们能尽快提出解决方案。

另一件需要考虑的事情是，Protactor 使用 Promise 来异步执行脚本，这在浏览器支持方面目前仍处于 IE11 的预览版中

【解决方案3】：

对于没有角度的网站，而不是 driver.get 使用下面的代码。

browser.driver.get("https://material.angularjs.org/latest/demo/radioButton");

在 IE 中也可以选择 Internet 选项>IE 选项并为所有区域启用保护模式

我设法在我的配置中通过以下功能解决了这个问题，js

 onPrepare: function () {
        browser.driver.ignoreSynchronization = true;// for non-angular set true. default value is false 
        browser.waitForAngularEnabled(false);   // for non-angular set false. default value is true  
      browser.driver.manage().window().setSize(1280, 1024);

       }, 
 capabilities: {
     browserName: 'internet explorer',
     platform: 'ANY',
     version: '11'
    },
