Cypress vs Playwright — Choosing for Your Stack
Cypress and Playwright are both excellent E2E frameworks — but choosing between them requires more than comparing features. Learn the architectural differences, when each framework excels, and how to.
E2E in Docker and Ephemeral Environments
Reproducible test environments are the foundation of reliable CI/CD. Learn how to use Docker Compose for local and CI E2E testing, and how to run smoke tests against ephemeral preview deployments.
Playwright Practices That Survive Growth
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.
Debugging Failed Playwright Tests Like a Pro
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.
Parallel Runs, Sharding, and CI-Ready Playwright
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 and Accessibility Checks in Playwright
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.
Auth, Storage State, and Multi-User Flows
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.
API Testing with Playwright
Learn how to use Playwright's APIRequestContext for backend testing. Seed test data via API before UI tests, validate responses, handle authentication headers, and decide when API tests beat E2E.
Auto-Waiting, Assertions, and Killing Flakes
Master Playwright's web-first assertions and auto-waiting to eliminate flaky tests. Learn why waitForTimeout is a bug, when networkidle helps, how expect.poll works, and whether to retry or fix the.
Page Objects vs Fixtures — Structuring Playwright Tests
Compare the classic Page Object Model with Playwright's fixture-based composition. Learn when each pattern wins, how to avoid god objects, and structure test code for maintainability at scale.
Locators That Don't Break
Master Playwright's locator strategy. Learn why role-based selectors are superior to CSS, when to use test IDs, how to filter and chain locators, and avoid the brittle patterns that break on every UI.
Playwright from Scratch — Setup and First Test
Learn why Playwright is the modern choice for E2E testing. Set up your first project, write a reliable test using auto-waiting and accessible selectors, and understand the browser/context/page mental.
Test Levels Explained — Component, Integration, System, Acceptance
What is each test level responsible for? Learn the scope, objectives, test basis, and typical defects for component, integration, system, and acceptance testing.
Types of Tests and When to Use Them
Unit, integration, E2E, manual, exploratory — every type has its place. Learn the test pyramid vs testing trophy debate and how to make smart trade-offs.
