Quality Engineering, Automated.

Test code is code. Learn how to structure, name, review, and own automated test suites so they stay useful instead of becoming technical debt.

Bad test data is the silent killer of automation. Learn how to create isolated, repeatable test data without pollution, race conditions, or environment coupling.

Time is finite. Not every test can be automated. Learn how to score your test backlog using risk, frequency, and cost — and when to say no to low-value automation.

The test pyramid is simple in theory — unit, integration, E2E. In practice, teams struggle with where to draw boundaries, how to balance layers, and what happens when you get it wrong.

Not every test should be automated. Learn the decision framework that separates high-value automation from expensive mistakes — and when exploratory testing wins.

Most test suites rot over time. Tests become flaky, slow, and ignored. Learn the practices that keep Playwright tests valuable as your team grows: ownership, tagging, smoke vs regression, locator.

Failed tests are not problems — they're clues. Learn how to use Playwright's UI mode, trace viewer, headed debugging, and artifact analysis to isolate flaky steps, understand root causes, and fix.

Playwright tests can run in parallel across multiple workers and even multiple machines. Learn how to configure workers, shard test suites for CI, collect trace and video artifacts, and set up a.

Visual regression tests catch UI changes you didn't intend. Accessibility tests catch barriers you didn't notice. Learn when visual testing helps, when it's noise, and how to integrate axe-core for.

Authentication in tests is deceptively hard. Learn how to use Playwright's storageState to log in once and reuse sessions, support multi-role testing, and avoid the most common security and.
