CSV Data Verification with Selenium & Java: A Step-by-Step Guide
Introduction
When performing automated testing, it’s crucial to ensure that the data displayed on a webpage matches the data that is downloaded or exported, especially when users download reports or datasets. A common scenario involves verifying that the data shown on a webpage and the data in a CSV file are identical.
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:
- Retrieve the data displayed in the table on the webpage.
- Download the CSV file from the webpage.
- Read and extract the data from the downloaded CSV file.
- Verify that the data in the CSV matches the data displayed on the page.
