How can I use the selenium WebDriver for scrolling within the scroll bar?

160    Asked by DrucillaTutt in QA Testing , Asked on Apr 5, 2024

 I am currently testing a web-based application that contains a scrollable element within a larger scrollable page. Describe to me how can I use Selenium’s WebDriver to scroll within the inner scrollbar of this element to ensure that all content should be visible and accessible during my automated testing.

In the context of selenium, you can scroll within the ban inner scrollbar in selenium WebDriver by using the “execute_script” method for execution of javascript coding that scrolls the desired element. Here is an example given:-


















From selenium import webdriver
From selenium.webdriver.common.by import By
From selenium.webdriver.support.ui import WebDriverWait
From selenium.webdriver.support import expected_conditions as EC
# Initialize the WebDriver (e.g., Chrome)
Driver = webdriver.Chrome()
# Navigate to the webpage containing the scrollable element
Driver.get(https://example.com)
# Find the scrollable element using its CSS selector or XPath
Scrollable_element = driver.find_element(By.CSS_SELECTOR, “your_scrollable_element_selector”)
# Scroll the inner scrollbar of the element using JavaScript
Driver.execute_script(“arguments[0].scrollTop = arguments[1];”, scrollable_element, 500)
# Wait for the content to load if necessary
# For example, wait for a specific element to become visible after scrolling
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, “your_content_element_selector”)))
# Continue with your testing or verification steps

Here is also the python coding snippet given of using selenium WebDriver for scrolling within an inner scrollbar of a web-based element:-

From selenium import webdriver
From selenium.webdriver.common.by import By
From selenium.webdriver.common.keys import Keys
From selenium.webdriver.support.ui import WebDriverWait
From selenium.webdriver.support import expected_conditions as EC
# Initialize the WebDriver (e.g., Chrome)
Driver = webdriver.Chrome()
# Navigate to the webpage containing the scrollable element
Driver.get(https://example.com)
# Find the scrollable element using its CSS selector or XPath
Scrollable_element = driver.find_element(By.CSS_SELECTOR, “your_scrollable_element_selector”)
# Scroll the inner scrollbar of the element using the send_keys method
# For example, you can send the Page Down key to scroll down
Scrollable_element.send_keys(Keys.PAGE_DOWN)
# Wait for the content to load if necessary
# For example, wait for a specific element to become visible after scrolling
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, “your_content_element_selector”)))
# Continue with your testing or verification steps
