Steps
install @axe-core/playwright and import { AxeBuilder } from '@axe-core/playwright' in the test file
instantiate new AxeBuilder({ page }) and call .analyze() to run a full-page scan and return violations
use .include(selector) to scope the scan to a specific region of the page, such as a modal or newly rendered component
use .disableRules([...]) to temporarily exclude specific axe rules that are known false positives or out of scope for the current test
assert on the returned violations array (e.g. expect(results.violations).toEqual([])) so the test fails when new accessibility issues are introduced
Known gotchas
AxeBuilder injects and runs axe-core inside the page context, so scans of iframed content need the iframe's own page/frame passed in or explicit inclusion
a clean scan does not guarantee full accessibility -- axe-core only catches programmatically detectable issues, not all WCAG success criteria
