Alert doesn't close using Selenium WebDriver with Google Chrome.

Question

I have the following Selenium script for opening alert on rediff.com:

public class TestC {
    public static void main(S         


        

Answer 1

I'm pretty sure your problem is a very common one, that's why i never advise using Thread.sleep(), since it does not guarantee the code will run only when the Alert shows up, also it may add up time to your tests even when the alert is shown.

The code below should wait only until some alert is display on the page, and i'd advise you using this one Firefox and IE9 aswell.

public class TestC {
    public static void main(String[] args) throws InterruptedException, Exception {
        System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
        WebDriver driver = new ChromeDriver();   
        WebDriverWait wait = new WebDriverWait(driver, 5);

        driver.get("http://www.rediff.com/");
        driver.findElement(By.xpath("//*[@id='signin_info']/a[1]")).click();
        driver.findElement(By.id("btn_login")).click();

        wait.until(ExpectedConditions.alertIsPresent());

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

Mostly all that is done here, is changing Thread.sleep(), for a condition that actually will only move forward on the code as soon a alert() is present in the page. As soon as someone does, it wil switch to it and accept.

You can find the Javadoc for the whole ExpectedConditions class here.

Unfortunately AlertIsPresent doesn't exist in C# API http://selenium.googlecode.com/git/docs/api/dotnet/index.html

You can use something like this:

private static bool TryToAcceptAlert(this IWebDriver driver)
{
    try
    {
        var alert = driver.SwitchTo().Alert();
        alert.Accept();
        return true;
    }
    catch (Exception)
    {
        return false;
    }
}


public static void AcceptAlert(this IWebDriver driver, int timeOutInSeconds = ElementTimeout)
{
    new WebDriverWait(driver, TimeSpan.FromSeconds(timeOutInSeconds)).Until(
        delegate { return driver.TryToAcceptAlert(); }
        );
}
