Complete Curriculum Breakdown

Why Playwright?

Understand why Playwright is the go-to tool for modern UI automation and how it stacks up against Selenium and Cypress

Install and First Test

Set up Playwright from scratch, understand the project structure, configure it properly, write your first test, and learn every way to run and debug it

Selectors and Locators

Master Playwright's locator strategies: getByRole, getByText, getByLabel, getByTestId, CSS, XPath, filtering, chaining, assertions, and the Playwright Inspector

Assertions

Master Playwright's auto-retrying assertions, soft assertions, negative checks, snapshots, and build reusable assertion patterns for bulletproof tests

Page Object Model in Playwright

Master the Page Object Model pattern in Playwright -- structure page classes, build reusable components, use custom fixtures, and write maintainable test suites with TypeScript

Handling Complex Scenarios

Master iframes, new tabs, dialogs, file uploads, drag-and-drop, keyboard/mouse actions, dropdowns, date pickers, and advanced wait strategies in Playwright

API Mocking and Network Interception

Intercept, mock, and monitor API calls in Playwright -- control your test data, simulate errors, record HAR files, and bypass authentication

Visual Testing

Catch CSS regressions, layout shifts, and broken styling with Playwright screenshot comparison -- baselines, thresholds, dynamic content, responsive testing, CI/CD setup, and third-party tools

CI/CD Integration

Run Playwright tests in CI pipelines -- GitHub Actions, Jenkins, GitLab CI, Docker, sharding, artifacts, debugging failures, and parallel execution strategies

Practice: Automate a Full App

Build a complete end-to-end test suite from scratch -- test planning, page objects, fixtures, data-driven tests, API mocking, visual testing, CI pipeline, and the mindset of a senior automation engineer

Frequently Asked Questions

Why are modern teams migrating from Selenium to Playwright?

Playwright eliminates test flakiness with built-in auto-waiting, runs tests in parallel across ultra-light browser contexts, provides native network mocking, and includes the visual Trace Viewer for instantaneous failure diagnosis.
