Playwright TypeScript | Data-Driven Testing Framework 🔥 | One Utility to Read CSV, Excel & JSON

Learn how to build a scalable Data-Driven Testing framework in Playwright using TypeScript. In this tutorial, we create a unified utility that automatically reads test data from CSV, Excel, or JSON files using a single function.

Topics covered in this session:

• Detecting file types using path.extname
• Creating a unified data reader utility
• Reading CSV, Excel, and JSON test data
• Using switch statements for dynamic file handling
• Integrating the data reader with Playwright tests
• Designing scalable automation framework utilities

This approach is commonly used in real-world automation frameworks where test data may come from multiple sources such as CSV files, Excel spreadsheets, or JSON files. By building a unified data reader utility, we make our Playwright automation framework more flexible, scalable, and easier to maintain.
