Playwright
Robust end-to-end tests with Playwright and TypeScript: cross-browser across Chromium, Firefox and WebKit, auto-waiting, API mocking and integration into CI/CD pipelines.
Playwright is a modern end-to-end testing framework from Microsoft designed for reliable and fast tests across all major browsers. With its powerful API, automatic waiting functionality, and comprehensive browser support, Playwright enables robust testing for modern web applications. The framework offers native TypeScript support, parallel test execution, and integrated debugging tools.

- Where is (test) automation really worthwhile
- Different types of tests and the test pyramid
- How do I find the right test strategies and test cases – Overview and Architecture of Playwright:
- Comparison Playwright vs. Cypress vs. Selenium
- Browser automation and test runner
- Installation and project setup – Fundamentals of Test Development:
- Test structure and best practices
- Selectors and locators
- Actions and assertions
- Auto-waiting and retry mechanisms – Advanced Test Scenarios:
- Forms and user interactions
- Navigation and multi-page scenarios
- File upload and download
- Drag & drop and complex interactions – Browser Context and Isolation:

The course is based on refined and tested course material with explanation, practical exercises, course project with code, solution code, and further information.
You will not only learn these concepts but also implement them practically.
The actual course content may differ from the above depending on the trainer, delivery, duration and the composition of participants.

More about Playwright
Playwright is a modern end-to-end testing framework developed by Microsoft, designed for reliable tests across all major browsers. It provides a unified API for Chromium, Firefox, and WebKit, enabling true cross-browser testing with automatic waiting functionality and robust test isolation.Further resources:
History
Playwright was developed in 2020 by Microsoft, primarily by Andrey Lushnikov and the team that had previously worked on Puppeteer at Google. The project emerged from the desire to create a modern testing framework that overcomes the limitations of existing tools and provides true cross-browser support.
Development was significantly influenced by experience with Puppeteer, with Playwright adopting many concepts but extending them with a focus on multi-browser support and test stability. Key milestones included the introduction of auto-waiting (2020), Trace Viewer for better debugging (2021), and Component Testing (2022). The integration of Codegen for automatic test generation revolutionized test development.
Today, Playwright is one of the fastest-growing testing frameworks and is used by companies like Microsoft, Bing, and VS Code itself. It has set new standards for cross-browser testing and, with its TypeScript-first architecture and comprehensive browser support, offers a modern alternative to established tools. The active community and continuous development by Microsoft ensure the framework's future viability.
