Overview
Playwright is an open-source framework for end-to-end testing of web applications. It provides a unified API to automate browsers across different platforms, including Chromium, Firefox, and WebKit. Playwright supports cross-browser testing, headless execution, and network interaction simulation, ensuring reliable and comprehensive test coverage. Its robust features enhance testing efficiency and accuracy.
Students Prerequisites
- Basic knowledge of JavaScript or TypeScript will be beneficial.
- Understanding fundamental web development concepts and familiarity with browser operations is helpful.
Course Curriculum
Module 1: Introduction to Playwright
What is Playwright?
