Why Use AShot for Screenshots?
Selenium’s built-in screenshot method only captures the visible viewport. AShot fills this gap by scrolling through the page and stitching the screenshots seamlessly, giving you the entire webpage in one image — ideal for UI testing and bug reporting.

How the Code Works – Step-by-Step Explanation:
Setup WebDriver with WebDriverManager
Automatically downloads and sets the right ChromeDriver version — no manual driver management needed.

Launch Chrome Browser
Opens a new Chrome window using Selenium.

Directs the browser to the target job portal site.

Take Full-Page Screenshot with AShot

Uses viewportPasting(100) strategy to scroll and capture the entire page.

Uses WebDriverCoordsProvider to correctly stitch images with accurate coordinates.

Captures the image and stores it in a Screenshot object.

Create Timestamped Filename
Generates a unique filename with date and time to avoid overwriting previous screenshots.

Save Screenshot to Disk
Writes the screenshot image to a specified folder using Java’s ImageIO.

Handle Exceptions
Catches any IO issues that might occur during file saving.

Clean Up
Quits the browser to free up system resources.

Pro Tips:
Directory Creation: Before saving, check if the target folder exists and create it if needed for smooth execution.

Headless Mode: Run Chrome in headless mode to take screenshots without opening a visible browser window, ideal for CI pipelines.

Element-Specific Screenshots: AShot also lets you capture specific elements instead of full pages — great for focused UI tests.

Final Thoughts
This setup gives you reliable, full-page screenshots to enhance your test automation reports and catch UI bugs effectively. AShot combined with Selenium is a must-have tool for any serious Java automation engineer.
