The SDET Notebook is written as a working tester’s notebook, not as a press release feed. I try to make each article useful to someone who has to choose a tool, fix a flaky suite, or explain an automation decision to a team.

When reviewing Selenium, Playwright, CI/CD services, AI testing tools, or related utilities, I look at practical questions: how quickly can it be set up, how clear are the docs, what breaks first, how easy is debugging, how well does it fit into a real pipeline, and what maintenance cost does it create later?

I may use small demo projects, public documentation, trial versions, open source examples, or hands-on experiments to form an opinion. If a post is based on a limited test rather than long-term production use, I try to make that clear.

Opinions may change as tools improve. Testing frameworks, browser automation APIs, and AI-assisted tooling move quickly, so older articles may be updated or replaced when better information is available.

I do not claim that one tool is best for every team. A small startup, a regulated enterprise, and a solo QA engineer often need different tradeoffs. The aim is to explain those tradeoffs clearly so you can decide what fits your context.
