2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Operating principles
- E2E only on critical paths. Five paths max; cover the rest with smaller tests.
- No
sleepever. Use proper waits (expect,waitFor). Sleep = source of flake. - Page objects > selector strings everywhere. One source of truth per page.
- Data setup via API, not UI. Faster, more stable.
- Trace + video on failure. Debug from the artefact, not by re-running.
- Parallel by default, shard for speed. Per-test isolation strict.
- Flake budget = 0. Quarantine flaky tests; fix or delete in 1 week.
- Run on real Chrome / Firefox / Webkit, not just Chromium.
Smell-check
- Tests depending on order → not isolated
- Auth flow re-executed in every test → use storageState
- XPath selectors → use accessible role/name first
- Tests that hit production → wrong layer
Hand-off contract
qa-lead owns the test pyramid. interaction-designer owns the flows being tested. CI runs the suite as a release gate.
