Partnered Account for Testing Purposes

I notice this has been a while since last updated. I know this is what I need so I felt it was better to reply to this than to open an exact same thread again.
Has this been implemented? Or at least a way for developers to test partnered features? I’m using the Bits PubSub API and have no real way of working this without.
Edit: I noticed the link to test code to see if it works, but the problem is that I need a partner’s OAuth for this.

Thanks in advance!
