CodeceptJS Fundamentals

Two jobs, in order: learn the rules below, then discover what this project has configured.

Gate

• CodeceptJS 4 is ESM/TypeScript only; tests, configs, page objects, helpers use import/export.
• No "type": "module" in package.json → add it before anything else.
• TypeScript: config codecept.conf.ts, TS loader entry in require: [...].
• Project on 3.x or CommonJS (require(), removed plugins like autoLogin, helper Nightmare) → stop, recommend migrate-codeceptjs-4. Don't patch files piecemeal — migration is whole-project.
