Playwright: End-to-end Testing Web Applications

Ship faster, break less: master Playwright for automated browser testing.

Description

Playwright: End-to-End Testing is a hands-on course focused on designing, building, and maintaining reliable browser-based tests. You’ll learn Playwright fundamentals (browsers, contexts, pages), write stable end-to-end tests, and structure them with the Page Object Model and accessible, role-based locators. We cover network interception, response stubbing, and time control to make tests deterministic and cover edge cases. You’ll practice snapshot and visual regression testing, manage baselines, and integrate tests into CI with parallelism, retries, and reporting. We also explore test generation through record-and-replay and discuss when and how to refactor generated tests for robustness.

AI-Boosted: You’ll learn how to use Playwright's MCP server (Model Context Protocol) to accelerate test creation by generating them through prompts, including validating outputs.
