+# 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)
+
+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).
+
+# Steps
+
+## 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):
+
+```python
+driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
+```
+
+## Infitinite scroll
+
+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):
+
+```python
+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
+```
+## Run your test
+
+```bash
+python lambdatest.py
+```
