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.

 

Objectives

 

• Understand core concepts of automation testing across UI, API, and database layers
• Set up and configure Playwright with C# (.NET) environment
• Write automated UI tests for React.js applications using MUI components
• Handle dynamic elements, asynchronous rendering, and modern UI behavior
• Perform API testing (GET, POST, PUT, DELETE) and validate responses
• Execute SQL queries to validate backend data integrity
• Design end-to-end test scenarios combining UI + API + database validation
• Debug, log, and analyze test execution results
• Apply best practices in test automation structure and maintainability
