In this guide, we’ll walk through the steps to automate this verification process using Selenium WebDriver in Java.

The Scenario

Imagine a webpage that displays data in a table, and there’s an Export to CSV button. When clicked, this button generates and downloads a CSV file containing all the data displayed on the page. Your task is to write a Selenium script that will:
