QA Checklist

Use this checklist when verifying a new JavaScript API test implementation:

• window.shoplift is defined on page load

• isHypothesisActive() returns true with ?slVariant=<id> URL parameter

• isHypothesisActive() returns expected results in a fresh incognito window (visitor is randomly assigned)

• Variant experience renders correctly

• Control experience renders correctly

• Error handling falls back to control (test by temporarily using an invalid hypothesis ID)

• No visual flicker during variant application

• For manual triggers: test only activates on the intended user action

• For analytics integrations: test data appears in your analytics platform

• For consent integrations: analytics data is only sent when consent is granted
