How to switch back to parent window in Selenium WebDriver?

Question

I need to close a child window and switch back to the parent window to perform some operations.

public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "http://www.example.com/";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}

@Test
public void testUntitled2() throws Exception {
    driver.get(baseUrl + "/info.php");
    driver.findElement(By.cssSelector("i.fa.fa-facebook-sq")).click();
    for (String winHandle : driver.getWindowHandles()) {
        driver.switchTo().window(winHandle);
    }

    // Perform the actions on new window
    driver.close(); // This will close new opened window

    //driver.switchTo().window(winHandleBefore); // I need to perform below

    driver.findElement(By.cssSelector("i.fa.fa-twitter-square")).click();
    driver.findElement(By.cssSelector("i.fa.fa-google-plus-  squ)).click();
    driver.findElement(By.cssSelector("i.fa.fa-linkedin-square")).click();
}

Answer 1

you can use this code for switching to child window and then back to parent window.

Code:

   String parentWindowHandler = driver.getWindowHandle(); // Store your parent window
            String subWindowHandler = null;

            Set<String> handles = driver.getWindowHandles(); // get all window handles
            Iterator<String> iterator = handles.iterator();
            while (iterator.hasNext()){
                subWindowHandler = iterator.next();
            }
            driver.switchTo().window(subWindowHandler); 

*****perform operations on child window******************

driver.switchTo().window(parentWindowHandler);

I hope this will solve your problem

Answer 2

Create one parentWindowHandle String variable before for loop and store windowhandle there. Once you are done with your operation with child window, go back to that parentWindowHandle .

String parentWindowHandle = driver.getWindowHandle();
/* You code to move to child window*/

//After you done with child window
driver.switchTo().window(parentWindowHandle);
