 1 | # How to scroll webpage in automation test in UnitTest on [LambdaTest](https://www.lambdatest.com/?utm_source=github&utm_medium=repo&utm_campaign=UnitTest-scroll)
 2 | 
 3 | If you want to test scrolling of a webpage using an automation test in UnitTest on LambdaTest, you can use the follwing steps. You can refer to sample test repo [here](https://github.com/LambdaTest/Python-UnitTest-Selenium).
 4 | 
 5 | # Steps
 6 | 
 7 | ## Scrolling to bottom of the page
 8 | 
 9 | To scroll to the bottom of the page, you can use the following line of code (refer to `scroll.py` for full code):
10 | 
11 | ```python
12 | driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
13 | ```
14 | 
15 | ## Infitinite scroll
16 | 
17 | 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 `scroll.py` for full code):
18 | 
19 | ```python
20 | SCROLL_PAUSE_TIME = 0.5
21 | 
22 | # Get scroll height
23 | last_height = driver.execute_script("return document.body.scrollHeight")
24 | 
25 | #controls how many times scrolled to bottom
26 | scroll_pass = 0
27 | 
28 | #change to True for infinite scroll
29 | while scroll_pass < 10:
30 |     # Scroll down to bottom
31 |     driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
32 | 
33 |     # Wait to load page
34 |     time.sleep(SCROLL_PAUSE_TIME)
35 | 
36 |     # Calculate new scroll height and compare with last scroll height
37 |     new_height = driver.execute_script("return document.body.scrollHeight")
38 |     if new_height == last_height:
39 |         break
40 |     last_height = new_height 
41 |     scroll_passs+=1
42 | ```
43 | ## Run your test
44 | 
45 | ```bash
46 | python scroll.py
47 | ```
