How to switch to new window in Selenium for Python?

Question

I am working on selenium automation project using Python.

I am facing an issue, which is handling multiple browser windows.

Scenario is as follows. When I click a link on the home page, a new window opens. In the newly opened window I cannot perform any actions, because the focus is still on the home page web driver.

Can anybody show me how to change focus from the background window to the newly opened window?

A possible solution is driver.switch_to.window(), but it requires the window's name. How to find out the window's name? If this is a wrong way to do this, can anybody give some code examples to perform this action?

Answer 1

On top of the answers already given, to open a new tab the javascript command window.open() can be used.

For example:

# Opens a new tab self.driver.execute_script("window.open()")  # Switch to the newly opened tab self.driver.switch_to.window(self.driver.window_handles[1])  # Navigate to new URL in new tab self.driver.get("https://google.com") # Run other commands in the new tab here 

You're then able to close the original tab as follows

# Switch to original tab self.driver.switch_to.window(self.driver.window_handles[0])  # Close original tab self.driver.close()  # Switch back to newly opened tab, which is now in position 0 self.driver.switch_to.window(self.driver.window_handles[0]) 

Or close the newly opened tab

# Close current tab self.driver.close()  # Switch back to original tab self.driver.switch_to.window(self.driver.window_handles[0]) 

Hope this helps.

You can do it by using window_handles and switch_to.window method.

Before clicking the link first store the window handle as

window_before = driver.window_handles[0] 

after clicking the link store the window handle of newly opened window as

window_after = driver.window_handles[1] 

then execute the switch to window method to move to newly opened window

driver.switch_to.window(window_after) 

and similarly you can switch between old and new window. Following is the code example

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()
