GraphQL Testing Strategy for Magento APIs

Maxim Mironjuk - October 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.

Contract Testing for REST APIs with OpenAPI

Maxim Mironjuk - October 24, 2025

An OpenAPI specification that no longer matches the implementation is worse than no documentation at all, it lies to you. Contract testing closes that gap automatically: tests check on every commit whether the backend implementation still honors the contract the specification defines.

Orchestrating Parallel Code Reviews with AI

Maxim Mironjuk - October 17, 2025

A single AI review pass usually tries to evaluate security, performance, style and architecture at once, and stays superficial in each individual area as a result. Parallel code reviews with specialized agents, each thoroughly checking only one aspect, deliver deeper findings in a shorter wait time, provided the results are then cleanly merged afterward.

Test Reports and Dashboards for the Whole Team

Maxim Mironjuk - October 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.

Running E2E Tests Reliably in GitLab CI

Maxim Mironjuk - October 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.

Test Data Management Strategies for E2E Suites

Maxim Mironjuk - October 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.

bashdb Debugger: Step by Step Bash Script Debugging

Maxim Mironjuk - October 14, 2025

Anyone who investigates a broken Bash script only with scattered echo lines wastes time and loses overview. The Bash debugger bashdb brings breakpoints, watchpoints and call stack analysis into the shell and makes debugging complex scripts as traceable as in any other programming language.

Symfony Profiler: Find Performance Bottlenecks in Seconds

Maxim Mironjuk - October 06, 2025

The Symfony Profiler is more than the debug bar at the bottom of the page. It shows precisely which database queries slow down a page, where event listeners consume excessive time, which caches are not hitting, and how much memory a request uses, all at the push of a button, without a single code change.

Playwright Component Testing: E2E for Individual React Components

Maxim Mironjuk - October 04, 2025

JSDOM based tests sometimes lie: they simulate browser behavior but do not test what a real browser actually does with a component. Playwright Component Testing renders every React component in a real Chromium, Firefox or WebKit instance, without spinning up the whole application.

Symfony Tests: Writing Functional Tests Efficiently

Maxim Mironjuk - October 03, 2025

Functional tests that are slow or keep failing because of database state problems simply do not get written, and the project loses its safety net. With WebTestCase, KernelTestCase, fixtures and clear conventions for database isolation, Symfony functional tests become the fast, reliable foundation of every deployment.
