manually creating new blocks with Babe

Question

Currently my consensus engine is Babe, and my finality gadget is Grandpa. But for testing environments I'm wondering if that there is a way to manually force the engine to produce a new block when I request.

Is there a way to implement this? or is it impossible for now?

Answer 1

One requirement of Babe is to produce at least one block per epoch.

You could create a "test" runtime with instant seal to achieve the result you desire.

Here are couple implementations of instant seal:
