How can I handle the window popup by using the Selenium WebDriver?

In the context of selenium, here is a detailed explanation given by using the several steps which are given below:-

Identify the window popup

You can use the “getwindowHandles()” to get all Windows handles currently available to the WebDriver.

You can identify the window handle for the pop-up window by comparing handles before and after the pop-up appears.

Switch the popup window

You can use the “switch to Window” method to switch the pop-up window based on its handle. You can perform actions specific to the pop-up window.

Handling the pop-up elements

You can try to locate and interact with the elements on the popup window by using the selenium WebDriver command.

Switch back to the main window

After completing the actions on the pop-up window, you can switch the WebDriver focus back to the main window by using the “switch to. Window” method for handling the main window.

Here is an example given in Java programming language for handling a window Popup in selenium WebDriver:-

Import org.openqa.selenium.By;
Import org.openqa.selenium.WebDriver;
Import org.openqa.selenium.chrome.ChromeDriver;
Public class HandlePopupExample {
    Public static void main(String[] args) {
        // Set the path to the ChromeDriver executable
        System.setProperty(“webdriver.chrome.driver”, “path_to_chromedriver”);
        // Initialize ChromeDriver
        WebDriver driver = new ChromeDriver();
        // Navigate to the webpage containing the popup
        Driver.get(https://example.com);
        // Get the handle of the main window
        String mainWindowHandle = driver.getWindowHandle();
        // Click on a button or perform an action that triggers the popup
        Driver.findElement(By.id(“popupButton”)).click();
        // Switch to the popup window
        For (String handle : driver.getWindowHandles()) {
            If (!handle.equals(mainWindowHandle)) {
                Driver.switchTo().window(handle);
                Break;

            }
        }
        // Perform actions on the popup window
        Driver.findElement(By.id(“username”)).sendKeys(“your_username”);
        Driver.findElement(By.id(“password”)).sendKeys(“your_password”);
        Driver.findElement(By.id(“loginButton”)).click();
        // Switch back to the main window
        Driver.switchTo().window(mainWindowHandle);
        // Continue with actions on the main window
        // For example, verify elements or perform further actions
    }
}
