Practical posts from real projects: Playwright, Cypress, API testing, CI/CD, and reliability at scale.
Most teams think they're saving money by skipping automation. The data says otherwise. Here's what poor test coverage actually costs in developer hours, incident response, and lost revenue.
Every testing tool now claims AI features. Most of them are marketing. Here's a practitioner's breakdown of what AI actually delivers in QA today, what's promising, and what you should ignore.
Most startups wait too long to invest in test automation. By the time they hire QA, they've accumulated months of untested code. Here's why automation should come first, and how to start small.
Most test suites break down at 500 tests. Slow CI, flaky runs, impossible maintenance. Here's the architecture and process that keeps suites fast and reliable at 10,000+ tests.
Your E2E tests are slow, flaky, and nobody trusts them. It's probably not the framework. Here are 7 anti-patterns I see in almost every test suite, and how to fix each one.
A practical guide to running Playwright tests in your CI pipeline, with config examples for GitHub Actions, GitLab CI, and Azure DevOps. Covers parallelism, artifacts, and cost optimization.
Everything you need to get Playwright running: from installation to your first test, page objects, CI integration, and reporting. A step-by-step guide for engineers new to Playwright.
E2E tests are slow and fragile across microservices. Contract tests are fast but don't test the full flow. Here's how to decide which to use where, with real examples from distributed systems.
Shift-left testing sounds great in theory. In practice, developers skip tests because the infrastructure makes it painful. Here's how to build a system where writing tests is the path of least resistance.
Page Object Model (POM) keeps your Playwright tests maintainable as your suite grows. Here's how to implement it properly, with TypeScript examples, fixtures, and patterns I use in production.
Flaky tests erode trust, slow CI, and waste engineering time. Here's the exact playbook I use to identify, categorize, and eliminate flake, with real examples from Playwright and Cypress suites.
A practical, engineer-first comparison: cross-browser, mobile emulation, parallelism, network control, multi-tab flows, selectors, debugging, and migration tips.
