Course Overview

Step into high-paying SDET and Automation Engineering roles. In this masterclass, you will build production-ready test automation frameworks from scratch using Playwright, TypeScript, and Python. You will automate complex web interactions, test RESTful backend APIs, handle authentication tokens, perform visual regression testing, and integrate test suites directly into CI/CD pipelines with real-time reporting.
