Automation Testing
Frameworks, tools and patterns for UI and mobile automation.
Automation testing is how modern QA teams ship every day without breaking production. Instead of clicking through the same regression checklist for the hundredth time, you write code — in Playwright, Selenium, Cypress, Appium or REST Assured — that exercises the same paths in seconds, on every pull request, in every browser.
This hub collects our deepest tutorials on framework design (Page Object Model, BDD, data-driven), tool-by-tool guides, CI/CD wiring with GitHub Actions and Jenkins, and the interview questions hiring managers are actually asking in 2026. Whether you are a manual tester making the jump or a senior SDET tuning flake, start with the pillars below and drill into the article list underneath.
If you are picking your first tool, our Playwright vs Selenium comparison and the Automation QA Engineer role guide will save you weeks. If you already write scripts and want to stop your CI from being red on Mondays, jump to the CI/CD flake playbook further down the page.
