Selenium Switch Tabs

by

A few words about Tab/Window switching/handling:

  • Always keep track of the Parent Window handle so you can traverse back later if required as per your usecase.

  • Always use WebDriverWait with expected_conditions as number_of_windows_to_be(num_windows) before switching between Tabs/Windows.

  • Always keep track of the Child Window handles so you can traverse whenever required.

  • Always use WebDriverWait with expected_conditions as title_contains("partial_page_title") before extracting the Page Title.

  • Here is your own code with some minor tweaks mentioned above:

    from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Firefox(executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get("http://www.facebook.com/")
print("Initial Page Title is: %s" %driver.title)
windows_before  = driver.current_window_handle
driver.execute_script("window.open('http://google.com')")
WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
windows_after = driver.window_handles
new_window = [x for x in windows_after if x != windows_before][0]
driver.switch_to.window(new_window)
WebDriverWait(driver, 20).until(EC.title_contains("G"))
print("Page Title after first window switching is: %s" %driver.title)
driver.close()
driver.switch_to.window(windows_before)
WebDriverWait(driver, 20).until(EC.title_contains("F"))
print("Page Title after second window switching is: %s" %driver.title)
driver.quit()

  • Console Output:

    Initial Page Title is: Facebook – log in or sign up
Page Title after first window switching is: Google
Page Title after second window switching is: Facebook – log in or sign up
