如何在使用java with selenium>的网页中出现警报时收到通知

Question

I am trying to automate a website, but there is sudden appearance of alert box which is related some feed back which i need to close that alert then only i can proceed to new level in that site. The problem is i am unable to find the alert box appears at particular time in that site. it appears randomly. How to solve my problem.

Answer 1

The fastest solution I can think up is to create a method that will get rid of the alert, something like

try{
    Alert alert = null;
    try {   
        alert = driver.switchTo().alert();  
    } catch (Exception e) {
        Robot robot = new Robot();
        robot.keyPress(27);
        robot.keyRelease(27);
    }

    if (alert != null) {
        alert.dismiss();
    }
  }

After that, you just have to call it within your code every time. I know this is not the best implementation, but it will work.

Answer 2

If you want to block unnecessary alert appearance during execution, you need to override alert function using JavascriptExecutor as below :-

((JavascriptExecutor)driver).executeScript("window.alert = function() { return true; }");

You should just run the above mentioned code once at every time when new page loading before doing other action. It will override the alert functionally and accept it internally.

Edited :- As you're saying it's a HTML alert window instead of JavaScript alert then above code wouldn't work, in this case you should hide this alert using JavascriptExecutor once at every time when new page loading before doing other stuff if it is found as below :

//find first alert element 
List<WebElement> alert = driver.findElements(..);
if(alert.size() > 0 && alert.get(0).isDisplayed())
{ 
    ((JavascriptExecutor)driver).executeScript("arguments[0].style.display = 'none'", alert.get(0));
}

Declare the global variable eg:

public boolean acceptNextAlert = true; 

Following is the function

public String closeAlertAndGetItsText() 
 {
        try {
          Alert alert = driver.switchTo().alert();
          String alertText = alert.getText();
          if (acceptNextAlert) {
            alert.accept();
          } else {
            alert.dismiss();
          }
          return alertText;
        }
        catch (NoAlertPresentException ex)
         { 
           ex.printStackTrace();
         }
        finally 
        {
          acceptNextAlert = true;
        }
        return StartUrl;
      }
}

Call this function

String c=closeAlertAndGetItsText();

I found the solution based on Saurabh's code

  List<WebElement> alert = driver.findElements(..);
    if(alert.size() > 0 && alert.get(0).isDisplayed())
    { 
        ((JavascriptExecutor)driver).executeScript("arguments[0].style.display = 'none'", alert.get(0));
    }

I have created class CloseAlert.java in my project and inside the class created a static method closeAlert. created two list for the elements which are in appeared alert box and called this class in my main class when ever the new page is opened and it works fine now.

 public class CloseAlert {
        static List<WebElement> alert;
        static List<WebElement> alert2;

        public static void AlertClose(WebDriver driver)
        {
            alert = driver.findElements(By.xpath("//a[@class='fsrCloseBtn']"));
            alert2 = driver.findElements(By.xpath("//div[@class='fsrDeclineButtonContainer']/a"));

            if(alert.size() > 0 && alert.get(0).isDisplayed()||alert2.size() > 0 && alert2.get(0).isDisplayed())
            { 
                if(driver.findElement(By.xpath("//div[@class='fsrDeclineButtonContainer']/a")).isDisplayed())
                {
                    System.out.println("Alert found with no thanks button");

                    driver.findElement(By.xpath("//div[@class='fsrDeclineButtonContainer']/a")).click();
                }
                else if(driver.findElement(By.xpath("//a[@class='fsrCloseBtn']")).isDisplayed())
                {
                    System.out.println("alert found with Close button" );
                    driver.findElement(By.xpath("//a[@class='fsrCloseBtn']")).click();
                }

            }

            }
