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. 00:00 Intro 01:27 Architecture 02:08 Step 1 - In utils folder create Unified Data Reader dataReader.ts 12:31 Step 2 - Use Unified Data Reader in test login.spec.ts 17:53 Step 3 - Run and check 21:00 QUIZ - https://forms.gle/jLHcq9k7fdoUd59W8 (Let me know your score in comments) GITHUB PROJECT - https://github.com/Raghav-Pal/Playwri... ▬▬▬▬▬▬▬ Share with all who may need this If my work has helped you, consider helping any animal near you, in any way you can Never Stop Learning Raghav Pal #Playwright #PlaywrightTesting #PlaywrightAutomation #DataDrivenTesting #AutomationFramework #SoftwareTesting #QAEngineer #TypeScript #TestAutomation #PlaywrightTutorial ▬▬▬▬ USEFUL LINKS ▬▬▬▬ ✅ ALL TUTORIALS - https://AutomationStepByStep.com/ ✅ DATA FORMATS JSON - https://bit.ly/3w450tq XML - https://bit.ly/3PqRneH ✅ OTHERS Virtualization on Windows - http://bit.ly/2SItIL9 Mock Interviews - https://bit.ly/3QGwwVJ Redis - https://bit.ly/2N9jyCG Misc - https://bit.ly/2Q2q5xQ Tools & Tips - https://bit.ly/2oBfwoR QnA Friday - https://bit.ly/2NgwGpw Sunday Special - https://bit.ly/2wB23BO 🙌 Connect with Raghav: Ask Raghav: https://bit.ly/2CoJGWf GitHub: https://github.com/Raghav-Pal Udemy: https://www.udemy.com/user/raghav-pal-3/ Shorts Eng - https://bit.ly/3H9bifV Shorts Hindi - https://bit.ly/3XY7XqN ➡️ Subscribe for more videos:    / @raghavpal   — Keywords: playwright data driven testing playwright csv testing playwright excel testing playwright json test data playwright automation framework playwright typescript tutorial playwright read csv playwright read excel playwright read json --
