How to Handle Windows-Based Popups in Selenium Using C#?

You can handle Windows-based popups in Selenium using C# by switching the driver's focus to the popup window and then interacting with it as needed. Here's how:

1. Identify the Popup Window

• Use the FindElement method: Locate the popup window using its unique identifier (e.g., title, class name, or ID).
• Use the SwitchTo method: Switch the driver's focus to the newly identified popup window.

2. Interact with the Popup Window

• Perform actions: Once you've switched to the popup window, you can interact with it using Selenium's commands, such as SendKeys, Click, or GetAttribute.
• Handle specific actions: For example, if you need to click a "Save" button, use the Click method on the corresponding element.

3. Close the Popup Window

• Use the Close method: After you've completed the necessary actions, close the popup window using the Close method.
• Switch back to the main window: After closing the popup, switch back to the main window using the SwitchTo method and the DefaultContent property.

Example Code

// Assuming the popup window title is "My Popup"
IWebElement popupWindow = driver.FindElement(By.CssSelector("title[text='My Popup']"));

// Switch to the popup window
driver.SwitchTo().Window(popupWindow.GetAttribute("id"));

// Perform actions within the popup window
// ...

// Close the popup window
driver.Close();

// Switch back to the main window
driver.SwitchTo().DefaultContent();

Practical Insights

• Handle multiple popups: If you encounter multiple popups, you can use the GetWindowsHandles method to retrieve a list of all open window handles. Then iterate through the list and switch to each window to handle it individually.
• Wait for the popup to appear: Use explicit waits to ensure the popup window has fully loaded before attempting to interact with it.
• Handle alerts: Use the Alert property to interact with JavaScript alerts that may appear within the popup window.
