Handling Alert in Selenium WebDriver (Selenium 2)

Question

driver.findElement(By.xpath(\"//input[@value=\'添加\']\")).click(); 
//Pops out an Alert and program stops, does not continue 

how to click the alert

Answer 1

Alert alert = driver.switchTo().alert();
alert.accept();

If you want to cancel the pop up use the following:

 alert.dismiss();

instead of

 alert.accept():

Answer 2

C# code:

IAlert alert = driver.SwitchTo().Alert();
alert.Accept(); 
System.Threading.Thread.Sleep(milliseconds);

Answer 3

IWebDriver driver = new ChromeDriver();
driver.Navigate().GoToUrl("http://skynet:8081/1.htm");

var selenium = new WebDriverBackedSelenium(driver, driver.Url);
selenium.Start();

selenium.Click("css=input[type=button]");

Assert.AreEqual(selenium.GetConfirmation(), "Are you sure?");
Assert.AreEqual("OK", selenium.GetAlert());

// <input type="button" onclick="if(confirm('Are you sure?')) alert('OK'); else alert('Cancel');" value="Alert test" />

driver.Quit();

Answer 4

As of the latest selenium 2 release, this can be done (at least using the FirefoxDriver):

    driver.switchTo().alert().accept();

Answer 5

In previous version of Selenium 2 I have had no choice that to handle alerts in Internet Explorer by overriding the window.alert in Javascript:

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
// Override window.alert to store the prompt and accept it automatically
js.ExecuteScript("window.alert = function(msg) { document.bAlert = true; document.lastAlert=msg; }");

// Do some stuff...

// Check for alert
Object o = js.ExecuteScript("return document.bAlert");
if (o != null && (bool)o == true)
{
    //retrieve the alert message
    o = js.ExecuteScript("return document.lastAlert");
    // Do something with the alert text
}

Selenium 2.0b3 has support for handling Alerts in IE and Firefox, so you can do the following:

IAlert alert = driver.SwitchTo().Alert();
// Get the text from the alert
string alertText = alert.Text;
// Accept the alert
alert.Accept();

However, I have not been able to get the above to work with Yes/No alerts (Dismiss() works for No but Accept() doesn't work for Yes). I'm in the process of looking at the IEDriver to work out why this is.

Answer 6

You will have to handle exception and run your handler code for Alert, for Java:

      try{
         driver.findElement(By.xpath("//input[@value='添加']")).click(); 
      } catch(org.openqa.selenium.UnhandledAlertException e){
         Alert alert = driver.switchTo().alert();
         alert.accept();
         // you logic here what you want to do next
      }  

Catch this exception, and then you can accordingly accept or reject alert.
