Playwright Test Automation for QA Engineers

A full working course on Playwright with TypeScript for QA engineers in large professional-services firms (Big 4 and similar). It covers the same ground as a comprehensive "zero to hero" Playwright curriculum: TypeScript essentials for test code, installation and project layout, running and debugging (CLI, UI mode, Inspector, codegen, Trace Viewer), locators and the strictness rule, web-first assertions, auto-waiting and the timeout hierarchy, every common UI component (inputs, checkboxes, radios, dropdowns, tooltips, dialogs, tables, date pickers, sliders, iframes), the Page Object Model and a scalable page architecture, custom fixtures, configuration and projects, environment variables and mobile emulation, authentication reuse through storageState, artifacts and reporters, visual regression testing, API requests, network interception and mocking, parallelism, retries, tags and flakiness control, Docker and CI on GitHub Actions. Every topic is taught the same way: the problem that exists without the feature, the feature that solves it, and the price you pay for using it. The course is written for people who will maintain a suite on a client engagement for years, not for people writing a demo test once — so review criteria, evidence for audit, secret handling and cost of maintenance are part of the material, not an appendix. By the end you should be able to build and maintain a Playwright suite unaided, and to pass an external certification-style exam on the same syllabus.

Lehrplan · 27 Einheiten

1Why Playwright, and what it actually does

Explain the two failure modes of legacy UI automation — timing flakiness and driver overhead — and how Playwright's architecture removes each

~1,2 Std.
2The TypeScript you actually need for test code

Read and write the JavaScript constructs that appear in every Playwright test: const/let, arrow functions, template literals, destructuring, objects and arrays

~1,7 Std.
3Installing Playwright and laying out the project

Install Playwright into a new repository and into an existing front-end repository without breaking either

~1,2 Std.
4Running and debugging: CLI, UI mode, Inspector, codegen, Trace Viewer

Run the suite, a folder, a file, a single test, a project, the last failures and only the tests affected by a change from the command line

~1,8 Std.
5The anatomy of a test: describe, hooks, steps, annotations

Structure a spec file with describe blocks and the four hooks, and say when each hook runs relative to workers

~1,2 Std.
6Locator syntax: CSS, text, XPath and chaining

Read the DOM vocabulary a locator depends on: tag, attribute, class, id, text node, parent and child

~1,2 Std.
7User-facing locators and the strictness rule

Apply the locator priority order: role, label, placeholder, text, alt, title, test id, CSS or XPath last

~1,7 Std.
8Filtering, relationships and lists of elements

Use filter() with hasText, hasNotText, has, hasNot and visible to narrow a set by content, by a descendant or by visibility

~1,2 Std.
