Scrolling to bottom of the page

To scroll to the bottom of the page, you can use the following line of code (refer to scroll.py for full code):

If you want to scroll to a page with infinite loading, like social network ones, facebook etc. You can use the following code (refer to lambdatest.py for full code):

SCROLL_PAUSE_TIME = 0.5

# Get scroll height
last_height = driver.execute_script("return document.body.scrollHeight")

#controls how many times scrolled to bottom
scroll_pass = 0

#change to True for infinite scroll
while scroll_pass < 10:
    # Scroll down to bottom
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

    # Wait to load page
    time.sleep(SCROLL_PAUSE_TIME)

    # Calculate new scroll height and compare with last scroll height
    new_height = driver.execute_script("return document.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height 
    scroll_passs+=1
