Run local, emulated Slack, GitHub, Gmail, Stripe, S3, and more with shared people and history. New activity arrives over time, so you can see how your app responds.
You build an app that connects to Slack, Gmail, or Stripe. To test it, you need accounts, data in those accounts, and activity for your app to respond to.
WorldFixture gives you local, fake versions of those services, already populated with connected data. New events arrive while your app runs.
Point your app at them, check that it works, then reset and test again.
