How do you switch to a new window in Selenium for Python?

Switching to a New Window in Selenium for Python

In Selenium automation using Python, handling multiple browser windows is a common task. When a link is clicked that opens a new window, the focus remains on the original window, preventing actions from being performed in the new one.

To switch the focus from the background window to the newly opened one, you can employ the driver.switch_to.window() method. However, this requires knowing the window's name.

Finding the Window's Name

To retrieve the window's name, you can utilize the window_handles property. It returns a list of currently active window handles. The window handle for the original window can be stored before clicking the link:

window_before = driver.window_handles[0]

After clicking the link, the window handle for the new window can be obtained:

window_after = driver.window_handles[1]

Switching to the New Window

Once you have the window handles, you can switch to the new window using the switch_to.window() method:

driver.switch_to.window(window_after)

Now, the focus is on the new window, allowing you to perform actions such as clicking elements and navigating the page.

Code Example

The following code demonstrates how to switch to a new window in Selenium for Python:

import unittest
from selenium import webdriver

class GoogleOrgSearch(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Firefox()

    def test_google_search_page(self):
        driver = self.driver
        driver.get("http://www.cdot.in")
        window_before = driver.window_handles[0]
        print(window_before)
        driver.find_element_by_xpath("//a[@href='http://www.cdot.in/home.htm']").click()
        window_after = driver.window_handles[1]
        driver.switch_to.window(window_after)
        print(window_after)
        driver.find_element_by_link_text("ATM").click()
        driver.switch_to.window(window_before)

    def tearDown(self):
        self.driver.close()

if __name__ == "__main__":
    unittest.main()
