How to make Selenium not wait till full page load, which has a slow script?

When Selenium loads a page/url by default it follows a default configuration with pageLoadStrategy set to normal. To make Selenium not to wait for full page load we can configure the pageLoadStrategy. pageLoadStrategy supports 3 different values as follows:

  1. normal (full page load)
  2. eager (interactive)
  3. none

Here is the code block to configure the pageLoadStrategy :

  • Firefox :

    from selenium import webdriver
    from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
    
    caps = DesiredCapabilities().FIREFOX
    caps["pageLoadStrategy"] = "normal"  #  complete
    #caps["pageLoadStrategy"] = "eager"  #  interactive
    #caps["pageLoadStrategy"] = "none"
    driver = webdriver.Firefox(desired_capabilities=caps, executable_path=r'C:\path\to\geckodriver.exe')
    driver.get("http://google.com")
    
  • Chrome :

    from selenium import webdriver
    from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
    
    caps = DesiredCapabilities().CHROME
    caps["pageLoadStrategy"] = "normal"  #  complete
    #caps["pageLoadStrategy"] = "eager"  #  interactive
    #caps["pageLoadStrategy"] = "none"
    driver = webdriver.Chrome(desired_capabilities=caps, executable_path=r'C:\path\to\chromedriver.exe')
    driver.get("http://google.com")
    

Note : pageLoadStrategy values normal, eager and none is a requirement as per WebDriver W3C Editor's Draft but pageLoadStrategy value as eager is still a WIP (Work In Progress) within ChromeDriver implementation.
