Trigger events within Developer Rig
Provide a method to trigger fake subscriptions/follows/cheers within the developer rig.

Testing Affiliate/Partner events is now possible with the Twitch CLI. See comments for more details.

We'll mark this as "completed" although this functionality is being provided in a different way rather than the Developer Rig.
Testing APIs for Affiliate/Partner features as they are made available is certainly a challenge, so we have introduced the Twitch CLI in beta which allows you to test such events.
At this time, you can trigger test events for subscribe, unsubscribe, gift, cheer, Bits-in-Extensions transactions, add Channel Points reward, update Channel Points reward, remove Channel Points reward, create a Channel Points redemption, and update a Channel Points redemption notice.
To provide additional feedback about the CLI, please use the Twitch CLI UserVoice category.
