STUDY PATH / 03 MOVES

Read, build, review.

Use each group to make a small piece of evidence in your own project.

01 / FOUNDATIONKnow the language and test basis.

Start with JS/TS, QA concepts, and test design.

Stages 1–2 →

02 / PRACTICEAutomate an observable result.

Exercise UI, API, database, and CI checks.

Stages 3–6 →

03 / SCALEReview reliability and risk.

Extend the suite with stronger architecture and strategy.

Stages 7–10 →
