Beginner Playwright Automation Testing (C# .NET + React.js with MUI) equips beginners with the knowledge and practical skills to create automated UI tests using Playwright, C# .NET, and React.js applications built with Material UI.
Duration 3 Days – 21 hrs.
Overview
This course is designed to equip participants with foundational skills in modern test automation using Playwright, tailored for systems built with C# (.NET) backend and React.js (with MUI) frontend.
The program provides a hands-on, beginner-friendly approach to automating UI testing, API testing, and SQL database validation, enabling participants to validate end-to-end system behavior. Trainees will learn how to write automation scripts in C# using Playwright for .NET, interact with modern frontend components such as Material UI elements, validate backend APIs, and verify data integrity in relational databases.
The course emphasizes real-world application, allowing participants to align automation practices with their existing systems, ensuring immediate applicability after training.
By the end of the program, participants will have built a strong foundation in automation testing and gained practical experience in designing and executing automated tests across the full application stack.
