Working with windows and tabs
Windows and tabs
Get window handle
WebDriver does not make the distinction between windows and tabs. If your site opens a new tab or window, Selenium will let you work with it using a window handle. Each window has a unique identifier which remains persistent in a single session. You can get the window handle of the current window by using:
// Navigate to Url
driver.get("https://www.selenium.dev/selenium/web/window_switching_tests/page_with_frame.html");
//fetch handle of this
String currHandle=driver.getWindowHandle();
assertNotNull(currHandle);driver.current_window_handle // Navigate to Url
driver.Url="https://www.selenium.dev/selenium/web/window_switching_tests/page_with_frame.html";
//fetch handle of this
String currHandle = driver.CurrentWindowHandle;
Assert.IsNotNull(currHandle);driver.window_handleawait driver.getWindowHandle();driver.windowHandleSwitching windows or tabs
Clicking a link which opens in a new window will focus the new window or tab on screen, but WebDriver will not know which window the Operating System considers active. To work with the new window you will need to switch to it. For this, we fetch all window handles, and store them in an array. The array position fills in the order the window is launched. So first position will be default browser, and so on.
//click on link to open a new window
driver.findElement(By.linkText("Open new window")).click();
//fetch handles of all windows, there will be two, [0]- default, [1] - new window
Object[] windowHandles=driver.getWindowHandles().toArray();
driver.switchTo().window((String) windowHandles[1]);
//assert on title of new window
String title=driver.getTitle();
assertEquals("Simple Page",title);from selenium import webdriver

if (!originalWindow.contentEquals(windowHandle)) {
driver.switchTo().window(windowHandle)
break
}
}
//Wait for the new tab to finish loading content
wait.until(titleIs("Selenium documentation"))
Closing a window or tab
When you are finished with a window or tab and it is not the last window or tab open in your browser, you should close it and switch back to the window you were using previously. Assuming you followed the code sample in the previous section you will have the previous window handle stored in a variable. Put this together and you will get:
//closing current window
driver.close();
//Switch back to the old tab or window
driver.switchTo().window((String) windowHandles[0]); #Close the tab or window
driver.close()
#Switch back to the old tab or window
driver.switch_to.window(original_window)
//closing current window
driver.Close();
//Switch back to the old tab or window
driver.SwitchTo().Window(windowHandles[0]); #Close the tab or window
driver.close
#Switch back to the old tab or window
driver.switch_to.window original_window
//Close the tab or window
await driver.close();
//Switch back to the old tab or window
await driver.switchTo().window(originalWindow);
//Close the tab or window
driver.close()
//Switch back to the old tab or window
driver.switchTo().window(originalWindow)
Forgetting to switch back to another window handle after closing a window will leave WebDriver executing on the now closed page, and will trigger a No Such Window Exception. You must switch back to a valid window handle in order to continue execution.
Create new window (or) new tab and switch
Creates a new window (or) tab and will focus the new window or tab on screen. You don’t need to switch to work with the new window (or) tab. If you have more than two windows (or) tabs opened other than the new window, you can loop over both windows or tabs that WebDriver can see, and switch to the one which is not the original.
Note: This feature works with Selenium 4 and later versions.
//Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB);
assertEquals("",driver.getTitle());
//Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW);
assertEquals("",driver.getTitle()); # Opens a new tab and switches to new tab
driver.switch_to.new_window('tab')
# Opens a new window and switches to new window
driver.switch_to.new_window('window')
//Opens a new tab and switches to new tab
driver.SwitchTo().NewWindow(WindowType.Tab);
Assert.AreEqual("", driver.Title);
//Opens a new window and switches to new window
driver.SwitchTo().NewWindow(WindowType.Window);
Assert.AreEqual("", driver.Title);Opens a new tab and switches to new tab:
driver.switch_to.new_window(:tab)Opens a new window and switches to new window:
driver.switch_to.new_window(:window)Opens a new tab and switches to new tabOpens a new window and switches to new window:
await driver.switchTo().newWindow('tab'); await driver.switchTo().newWindow('window');// Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB)
// Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW)
Quitting the browser at the end of a session
When you are finished with the browser session you should call quit, instead of close:
//quitting driver
driver.quit(); //close all windowsdriver.quit() //quitting driver
driver.Quit(); //close all windowsdriver.quitawait driver.quit();driver.quit()- Quit will:
- Close all the windows and tabs associated with that WebDriver session
- Close the browser process
- Close the background driver process
- Notify Selenium Grid that the browser is no longer in use so it can be used by another session (if you are using Selenium Grid)
Failure to call quit will leave extra background processes and ports running on your machine which could cause you problems later.
Some test frameworks offer methods and annotations which you can hook into to tear down at the end of a test.
/**

* https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/AfterAll.html

If not running WebDriver in a test context, you may consider using
try / finally which is offered by most languages so that an exception
will still clean up the WebDriver session.
try {
//WebDriver code here...
} finally {
driver.quit();
}
try:
#WebDriver code here...
finally:
driver.quit()
try {
//WebDriver code here...
} finally {
driver.Quit();
}
begin
#WebDriver code here...
ensure
driver.quit
end
try {
//WebDriver code here...
} finally {
await driver.quit();
}
try {
//WebDriver code here...
} finally {
driver.quit()
}
Python’s WebDriver now supports the python context manager,
which when using the with keyword can automatically quit the driver at
the end of execution.
with webdriver.Firefox() as driver:
# WebDriver code here...
# WebDriver will automatically quit after indentation
Window management
Screen resolution can impact how your web application renders, so WebDriver provides mechanisms for moving and resizing the browser window.
Get window size
Fetches the size of the browser window in pixels.
//Access each dimension individually
int width = driver.manage().window().getSize().getWidth();
int height = driver.manage().window().getSize().getHeight();
//Or store the dimensions and query them later
Dimension size = driver.manage().window().getSize();
int width1 = size.getWidth();
int height1 = size.getHeight();
# Access each dimension individually
width = driver.get_window_size().get("width")
height = driver.get_window_size().get("height")
# Or store the dimensions and query them later
size = driver.get_window_size()
width1 = size.get("width")
height1 = size.get("height")
//Access each dimension individually
int width = driver.Manage().Window.Size.Width;
int height = driver.Manage().Window.Size.Height;
//Or store the dimensions and query them later
System.Drawing.Size size = driver.Manage().Window.Size;
int width1 = size.Width;

# Access each dimension individually
width = driver.manage.window.size.width
height = driver.manage.window.size.height
# Or store the dimensions and query them later
size = driver.manage.window.size
width1 = size.width
height1 = size.height
Access each dimension individually(or) store the dimensions and query them later
const { width, height } = await driver.manage().window().getRect(); const rect = await driver.manage().window().getRect();
const windowWidth = rect.width;

val width = driver.manage().window().size.width
val height = driver.manage().window().size.height
//Or store the dimensions and query them later
val size = driver.manage().window().size
val width1 = size.width
val height1 = size.height
Set window size
Restores the window and sets the window size.
driver.manage().window().setSize(new Dimension(1024, 768));driver.set_window_size(1024, 768)driver.Manage().Window.Size = new Size(1024, 768);driver.manage.window.resize_to(1024,768)await driver.manage().window().setRect({ width: 1024, height: 768 });driver.manage().window().size = Dimension(1024, 768)Get window position
Fetches the coordinates of the top left coordinate of the browser window.
// Access each dimension individually
int x = driver.manage().window().getPosition().getX();
int y = driver.manage().window().getPosition().getY();
// Or store the dimensions and query them later
Point position = driver.manage().window().getPosition();
int x1 = position.getX();

#Access each dimension individually
x = driver.manage.window.position.x
y = driver.manage.window.position.y
# Or store the dimensions and query them later
rect = driver.manage.window.rect
x1 = rect.x
y1 = rect.y
Access each dimension individually(or) store the dimensions and query them later
const { x, y } = await driver.manage().window().getRect(); const rect = await driver.manage().window().getRect();

val y = driver.manage().window().position.y
// Or store the dimensions and query them later
val position = driver.manage().window().position
val x1 = position.x
val y1 = position.y
Set window position
Moves the window to the chosen position.
// Move the window to the top left of the primary monitor
driver.manage().window().setPosition(new Point(0, 0));
# Move the window to the top left of the primary monitor
driver.set_window_position(0, 0)
// Move the window to the top left of the primary monitor
driver.Manage().Window.Position = new Point(0, 0);
driver.manage.window.move_to(0,0)
// Move the window to the top left of the primary monitor
await driver.manage().window().setRect({ x: 0, y: 0 });
// Move the window to the top left of the primary monitor
driver.manage().window().position = Point(0,0)
Maximize window
Enlarges the window. For most operating systems, the window will fill the screen, without blocking the operating system’s own menus and toolbars.
driver.manage().window().maximize();driver.maximize_window()driver.Manage().Window.Maximize();driver.manage.window.maximizeawait driver.manage().window().maximize();driver.manage().window().maximize()Minimize window
Minimizes the window of current browsing context. The exact behavior of this command is specific to individual window managers.
Minimize Window typically hides the window in the system tray.
Note: This feature works with Selenium 4 and later versions.
