What happens inside
Microlab for testers who inherited suites with monster selectors. You will profile pages, negotiate ARIA improvements with designers on paper, and practice incremental refactors without freezing feature work.
Included cadence
- ↗ DOM archetype flashcards
- ↗ Shadow DOM lab in controlled sandbox
- ↗ Diff exercises between role locators and test IDs
- ↗ Office hour on canvas-heavy apps (limitations flagged)
- ↗ Office hour on Intl formatting traps
- ↗ Graded capstone on shrinking a legacy selector map
- ↗ Recording of all demos
Outcomes you can audit
Straight answers
Canvas heavy app?
We explain limitations honestly; you will draft a risk memo instead of fake automation coverage.
What if designers resist test IDs?
We role-play negotiation scripts; legal approval for sharing designs is on you.
Recording reuse?
Personal use only; redistribution violates cohort agreement.
Participant notes
“Selector Hygiene Clinic forced me to map shadow roots on paper before touching VS Code. Small cohort, a little pricey, but saved a sprint.”
