Steps
install @percy/cli and @percy/playwright as dev dependencies
import percySnapshot from '@percy/playwright' in the test file
call await percySnapshot(page, 'unique snapshot name') at each point in a Playwright test where a visual baseline should be captured
wrap the test run with percy exec -- <test command> so Percy's CLI agent is running and can receive snapshots, with PERCY_TOKEN set in the environment
review the resulting build in the Percy dashboard, where new or changed snapshots are queued for visual approval
Known gotchas
percySnapshot calls are no-ops that log a warning if the test is not run through percy exec, so snapshots silently do nothing under a plain playwright test invocation
each snapshot name must be unique within a build; reusing a name across tests overwrites the prior snapshot rather than creating a second comparison point
