1. Fixtures vs. Factories: Generating Test Data Correctly

   Dec 23, 2025

   Fixtures and factories solve the same problem in different ways: predictable, fixed test data versus flexible data generated at runtime. This article shows when each approach works best, how factories can avoid becoming overengineered, and how a hybrid model combining both keeps end to end tests for customer data and product data both stable and readable.

2. Understanding Playwright Auto-Waiting Instead of Using sleep()

   Dec 8, 2025

   Stabilizing E2E tests with page.waitForTimeout or fixed sleep calls only fights symptoms instead of causes. Before every action, Playwright automatically checks whether an element is visible, stable, enabled and actually clickable, and repeats this check until it passes or a timeout is reached. This article shows how these actionability checks work, why fixed wait times mask flakiness instead of fixing it, and how to precisely diagnose timeout errors with the Trace Viewer.

3. PWA Testing Strategy: Offline, Install, Service Worker

   Dec 2, 2025

   Progressive Web Apps bring service workers, offline fallbacks and install prompts that classic E2E tests do not cover. Anyone using Cypress or Playwright without a dedicated strategy for network simulation, cache invalidation and manifest validation misses exactly the bugs that confront customers with stale prices offline or right after a deploy. This article shows how PWA testing works reliably in practice.

4. MFTF: The Magento Functional Testing Framework in Detail

   Nov 18, 2025

   This article explains what the Magento Functional Testing Framework actually does, how its declarative XML structure fundamentally differs from imperative Cypress or Playwright code, and in which project phases MFTF still remains the right choice. Developers get a clear breakdown of when backend tests with MFTF make more sense than modern JavaScript E2E tests for the storefront.

5. Playwright Fixtures for Clean Test Isolation

   Nov 7, 2025

   Playwright fixtures replace fragile beforeEach blocks and shared global test state with clearly defined, reusable building blocks for setup and teardown. Once you understand built in fixtures like page, context and browser and start writing your own with test.extend, you get tests that run in parallel, never interfere with each other, and avoid duplicated setup code across files.

6. GraphQL Testing Strategy for Magento APIs

   Oct 25, 2025

   GraphQL APIs break many familiar REST testing patterns: a single endpoint, flexible query shapes, and a status code that stays 200 almost regardless of errors. Testing a Magento storefront over GraphQL requires different assertions, robust snapshot strategies, and a clear read on the errors array to reliably validate cart mutations, product queries, and checkout flows.

7. Test Reports and Dashboards for the Whole Team

   Oct 16, 2025

   A green checkmark in the CI pipeline says little about whether a test suite can actually be trusted by the team. Only once test results become visible as an HTML report, a Slack notification, and a trend dashboard do developers, testers, and product owners jointly see how stable, how flaky, and how fast their end-to-end tests really are.

8. Running E2E Tests Reliably in GitLab CI

   Oct 15, 2025

   Wiring Cypress or Playwright suites into GitLab CI naively leads to slow pipelines, flickering tests, and merge requests nobody trusts anymore. With the right Docker images, caching strategies, review app setups, artifact rules, parallelization, and retry mechanisms, E2E tests become a reliable gate instead of a dreaded bottleneck in the development process.

9. Test Data Management Strategies for E2E Suites

   Oct 15, 2025

   Most flaky E2E tests don't fail because of broken selectors, they fail because of poorly managed test data. Teams that consistently separate fixtures, factories, ownership models and cleanup strategies gain reproducible, parallelizable test runs that stay reliable even as suites grow and schemas change frequently.

10. Selective Testing: Running Only Affected Tests

    Sep 29, 2025

    Running a growing Cypress or Playwright suite in full on every commit quickly burns valuable minutes of feedback time and CI budget. This article shows in practice how feature tags, dependency graphs, and git-diff heuristics reliably identify affected tests, while scheduled full runs continue to serve as a safety net against overlooked regressions.
