角4等待状态下使用Java硒

Question

我有问题编写的Java硒，对工作的等待条件既角4角和1。我现在有，对于角1有效的解决方案是如下：

public static ExpectedCondition<Boolean> angularHasFinishedProcessing() { 
    return new ExpectedCondition<Boolean>() { 
     public Boolean apply(WebDriver driver) { 
      return Boolean.valueOf(((JavascriptExecutor) driver).executeScript(
        "return (window.angular !== undefined) &&" + 
          " (angular.element(document).injector() !== undefined) &&" + 
          " (angular.element(document).injector().get('$http').pendingRequests.length === 0)").toString()); 
     } 
    }; 
} 

public static void waitOnAngular(WebDriver driver){ 
    WebDriverWait wait = new WebDriverWait(driver, 15, 100); 
    wait.until(AdditionalConditions.angularHasFinishedProcessing()); 
} 

我正在寻找一些JavaScript来扩展这个apply（）方法来处理angular 4或者其他一些解决方案，人们已经成功地让selenium等待角度$ http请求与所有视图一起加载。

请参阅下面的pom.xml文件，查看我是哪个版本的selenium-java版本。

Answer 1

这是我在此之前一段时间发现，并用它相当成功等待的角度。但我不知道它是否适用于两者。

final String script = "var callback = arguments[arguments.length - 1];\n" + 
     "var rootSelector = \'body\';\n" + 
     "var el = document.querySelector(rootSelector);\n" + 
     "\n" + 
     "try {\n" + 
     " if (angular) {\n" + 
     "  window.angular.getTestability(el).whenStable(callback);\n" + 
     " }\n" + 
     " else {\n" + 
     "  callback();\n" + 
     " }\n" + 
     "} catch (err) {\n" + 
     " callback(err.message);\n" + 
     "}"; 

((JavascriptExecutor) getDriver()).executeAsyncScript(script, new Object[0]);
