使用 Selenium 测试 AngularJS [英] Testing AngularJS with Selenium

问题描述

我在堆栈 ASP MVC + AngularJS 上有一个 SPA 应用程序，我想测试 UI.现在我正在尝试使用 PhantomJS 和 WebKit 驱动程序的 Selenium.

这是一个示例测试页面 - 使用单个元素查看.列表项

从服务器动态加载并受 Angular 限制.

<li>文本</li><li>text2</li>

我正在尝试通过测试，但此行中有错误:

_driver.FindElements(By.TagName('li'))

此时没有加载的元素，_driver.PageSource 不包含元素.

如何等待物品加载?请不要建议 Thread.Sleep()

解决方案

这将等待页面加载/jquery.ajax(如果存在)和 $http 调用，以及任何伴随的摘要/渲染循环，将其放入实用程序函数中等一下.

/* C# 示例var pageLoadWait = new WebDriverWait(WebDriver, TimeSpan.FromSeconds(timeout));pageLoadWait.Until((司机) =>{返回(布尔)JS.ExecuteScript(@"*/尝试 {如果(document.readyState ！=='完成'){返回假；//页面尚未加载}如果(窗口.jQuery){如果(window.jQuery.active){返回假；} else if (window.jQuery.ajax && window.jQuery.ajax.active) {返回假；}}如果(窗口.角度){如果(！window.qa){//用于跟踪加载完成后的渲染周期完成情况窗口.qa = {doneRendering: 假};}//获取此应用程序的角度注入器(如有必要，更改元素)var injector = window.angular.element('body').injector();//存储用于这些检查的提供程序var $rootScope = injector.get('$rootScope');var $http = injector.get('$http');var $timeout = injector.get('$timeout');//检查是否摘要if ($rootScope.$$phase === '$apply' || $rootScope.$$phase === '$digest' || $http.pendingRequests.length !== 0) {window.qa.doneRendering = false;返回假；//Angular 消化或加载数据}如果(！window.qa.doneRendering){//设置超时以将角度渲染标记为完成$超时(功能(){window.qa.doneRendering = true;}, 0);返回假；}}返回真；}赶上(前){返回假；}/*");});*/

I have a SPA application on stack ASP MVC + AngularJS and I'd like to test the UI. For now I'm trying Selenium with PhantomJS and WebKit drivers.

This is a sample testing page - view with single element. The list items <li> load dynamically from server and are bounded by Angular.

<div id="items">
    <li>text</li>
    <li>text2</li>
</div>

I'm trying to pass a test and there is an error in this line:

_driver.FindElements(By.TagName('li'))

At this point there are no loaded elements and _driver.PageSource doesn't contain elements.

How can I wait for the items to load? Please do not suggest Thread.Sleep()

解决方案

This will wait for page loads / jquery.ajax (if present) and $http calls, and any accompanying digest/render cycle, throw it in a utility function and wait away.

/* C# Example
 var pageLoadWait = new WebDriverWait(WebDriver, TimeSpan.FromSeconds(timeout));
            pageLoadWait.Until<bool>(
                (driver) =>
                {
                    return (bool)JS.ExecuteScript(
@"*/
try {
  if (document.readyState !== 'complete') {
    return false; // Page not loaded yet
  }
  if (window.jQuery) {
    if (window.jQuery.active) {
      return false;
    } else if (window.jQuery.ajax && window.jQuery.ajax.active) {
      return false;
    }
  }
  if (window.angular) {
    if (!window.qa) {
      // Used to track the render cycle finish after loading is complete
      window.qa = {
        doneRendering: false
      };
    }
    // Get the angular injector for this app (change element if necessary)
    var injector = window.angular.element('body').injector();
    // Store providers to use for these checks
    var $rootScope = injector.get('$rootScope');
    var $http = injector.get('$http');
    var $timeout = injector.get('$timeout');
    // Check if digest
    if ($rootScope.$$phase === '$apply' || $rootScope.$$phase === '$digest' || $http.pendingRequests.length !== 0) {
      window.qa.doneRendering = false;
      return false; // Angular digesting or loading data
    }
    if (!window.qa.doneRendering) {
      // Set timeout to mark angular rendering as finished
      $timeout(function() {
        window.qa.doneRendering = true;
      }, 0);
      return false;
    }
  }
  return true;
} catch (ex) {
  return false;
}
/*");
});*/
