Unleash roll up&down consistency test

test.js

// you can run unleash locally with https://docs.getunleash.io/quickstart#i-want-to-run-unleash-locally
// create a toggle named flag-1 and add the rollout strategy sticky on userId
// then play around rolling up and down.
// Note: to run this you'll need to have an npm project (npm init) and add unleash dependency (npm i unleash-client)
