How to close child browser window in Selenium WebDriver using Java

Question

After I switch to a new window and complete the task, I want to close that new window and switch to the old window,

so here i written like code:

// Perform the click operation that opens new window  String winHandleBefore = driver.getWindowHandle();      // Switch to new window opened      for (String winHandle : driver.getWindowHandles()) {         driver.switchTo().window(winHandle);     }      // Perform the actions on new window       driver.findElement(By.id("edit-name")).clear();     WebElement userName = driver.findElement(By.id("edit-name"));     userName.clear();               try     {         driver.quit();     }      catch(Exception e)     {         e.printStackTrace();         System.out.println("not close");                 }  driver.switchTo().window(winHandleBefore);// Again I want to start code this old window 

Above I written code driver.quit() or driver.close(). But I am getting error. Can anybody help me...?

org.openqa.selenium.remote.SessionNotFoundException: The FirefoxDriver cannot be used after quit() was called.

Answer 1

To close a single browser window:

driver.close(); 

To close all (parent+child) browser windows and end the whole session:

driver.quit(); 

Answer 2

The logic you've used for switching the control to popup is wrong

 for (String winHandle : driver.getWindowHandles()) {         driver.switchTo().window(winHandle);     } 

How the above logic will swtich the control to new window ?

Use below logic to switch the control to new window

// get all the window handles before the popup window appears  Set beforePopup = driver.getWindowHandles();  // click the link which creates the popup window driver.findElement(by).click();  // get all the window handles after the popup window appears Set afterPopup = driver.getWindowHandles();  // remove all the handles from before the popup window appears afterPopup.removeAll(beforePopup);  // there should be only one window handle left if(afterPopup.size() == 1) {           driver.switchTo().window((String)afterPopup.toArray()[0]);  } 

// Perform the actions on new window

  **`//Close the new window`**      driver.close(); 

//perform remain operations in main window

   //close entire webDriver session     driver.quit();
