How to Avoid Full Page Load Waits in Selenium with Slow-loading Scripts?

Overcoming Full Page Load Waits in Selenium with Slow-loading Scripts

Selenium's default behavior is to wait until a page has fully loaded before proceeding with execution. However, this can become problematic when a page contains slow-loading JavaScript scripts. To avoid prolonged wait times, it's crucial to configure Selenium's pageLoadStrategy.

The pageLoadStrategy parameter allows you to specify the level of page loading desired:

• normal: Full page load (default)
• eager: Interactive page load (when the user can interact with elements, but the page might not be fully loaded)
• none: Do not wait for page load (useful for dynamic pages)

To limit unnecessary waiting, set the pageLoadStrategy to "eager" or "none":

Firefox:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities().FIREFOX
caps["pageLoadStrategy"] = "eager"
driver = webdriver.Firefox(desired_capabilities=caps, executable_path='path/to/geckodriver.exe')

Chrome:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities().CHROME
caps["pageLoadStrategy"] = "eager"
driver = webdriver.Chrome(desired_capabilities=caps, executable_path='path/to/chromedriver.exe')

Note: While "eager" is recommended, it's still under development in ChromeDriver. Refer to the discussion in "Eager” Page Load Strategy workaround for Chromedriver Selenium in Python" for details.

By configuring the pageLoadStrategy, you can prevent Selenium from waiting for slow-loading scripts to finish, significantly improving the execution speed of your scripts across different browser implementations.
