Browser Testing Notes is a practical blog for people who spend too much time asking why a test passed locally and failed in CI.

The site focuses on browser automation pain points: flaky Selenium and Playwright tests, cross-browser surprises, Selenium Grid maintenance, real browser testing, parallel execution, selectors, waits, test data, and the small infrastructure details that often decide whether a suite is useful or noisy.

The goal is not to crown a single perfect tool. Most teams inherit a mix of frameworks, browsers, pipelines, and legacy decisions. Browser Testing Notes is here to make those tradeoffs clearer with grounded explanations, comparison pages, debugging checklists, and opinionated notes on where common testing advice breaks down.

You will find content for QA engineers, SDETs, frontend developers, engineering managers, and anyone responsible for keeping browser tests fast, stable, and believable.
