# How to scroll webpage in automation test in Python-selenium on [LambdaTest](https://www.lambdatest.com/?utm_source=github&utm_medium=repo&utm_campaign=Python-selenium-scroll)
2+
3+
If you want to test scrolling of a webpage using an automation test in Python-selenium on LambdaTest, you can use the follwing steps. You can refer to sample test repo [here](https://github.com/LambdaTest/python-selenium-sample).
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 `lambdatest.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 lambdatest.py
47+
```
