1. Automating Accessibility Testing with axe-core

   Mar 25, 2026

   Automated accessibility testing with axe-core covers only about 30 to 40 percent of all WCAG criteria, but those categories, things like color contrast, missing alt text, and ARIA errors, can be reliably integrated into any Cypress or Playwright pipeline. This article shows how to configure thresholds, block CI builds only on new violations, and catch typical Magento- and Hyvä-specific barriers early.

2. Automating Touch Interaction Testing

   Mar 23, 2026

   Mobile storefronts live on touch gestures: swiping through image galleries, tapping filter buttons, dragging off-canvas menus. Testing these interactions with simulated mouse clicks alone misses ghost clicks, blocked scroll directions, and hover menus that are simply unreachable on a touchscreen. This article shows how to reliably simulate real touch events in Cypress and Playwright.

3. Parallel Test Execution for Faster CI Runs

   Mar 20, 2026

   Growing end-to-end test suites slow down every CI pipeline once tests run sequentially. This article shows how to distribute test suites across multiple CI workers, optimize load balancing based on real runtimes instead of raw file count, avoid resource conflicts on shared databases and sandbox accounts, and achieve noticeably faster test runs with Cypress Cloud, Playwright sharding, and GitLab CI matrix jobs.

4. Automating Schema Validation in API Tests

   Mar 15, 2026

   Anyone who checks every field of an API response individually with expect often misses silent breaking changes such as new required fields, changed types or removed enum values. Schema validation against JSON Schema or OpenAPI catches exactly these cases automatically, cuts test code significantly, and integrates smoothly into Cypress, Playwright and the CI pipeline, so frontend and backend reliably honor the same contract.

5. Test Retry Strategies Without Masking Flakiness

   Mar 15, 2026

   Letting tests rerun until they pass quietly pushes real bugs and race conditions out of sight and slowly erodes trust in the test suite itself. This article shows how to configure Cypress and Playwright retries correctly and how teams can turn repeated test runs into an early warning system instead of a convenient free pass.

6. Shift-Left Testing Culture: Moving Quality Before the Test Step

   Feb 25, 2026

   Shift-left testing means catching issues during design and while writing code, instead of leaving them to a dedicated QA phase at the end. Developers who write and own their own end to end tests, use static analysis consistently, and no longer throw code over the wall to QA, shorten feedback cycles noticeably and significantly reduce the cost of every bug found.

7. Testing Magento Admin Workflows End-to-End

   Feb 23, 2026

   Magento admin workflows like product creation, order management and catalog price rules determine revenue and data integrity even though customers never see them. End to end tests with Cypress or Playwright close exactly the gap that PHPUnit integration tests leave open: session handling, grid interactions and mass actions in a real browser, with clear prioritization by maintenance cost and business risk.

8. Making Database Seeding for E2E Tests Reproducible

   Feb 4, 2026

   Running E2E suites against an unknown database state produces flaky tests instead of reliable results. This article shows how to put Magento stores into an exactly known state before every test run, through API calls, CLI commands, or direct SQL fixtures, and how to reset that state quickly between runs without seeding everything from scratch every time.

9. Mutation Testing: Do Your Tests Actually Test Anything?

   Feb 1, 2026

   A test suite with 100 percent line coverage can still be worthless if tests merely execute code instead of verifying its behavior. Mutation testing deliberately introduces small bugs into your code and checks whether your tests actually notice. Applied correctly to PHP and PHPUnit, it exposes blind spots that classic coverage metrics systematically hide.

10. Testing the Magento Checkout Flow End-to-End

    Jan 30, 2026

    The checkout is the highest-value path in any Magento store and, at the same time, the most fragile, because frontend state, asynchronous AJAX calls, and external payment APIs all converge there. This article shows how to test cart, shipping methods, payment methods, and order confirmation end-to-end with Cypress and Playwright, reliably simulate payment gateways in sandbox mode, and cleanly separate guest and logged-in checkout paths.
