#then_ruby_promise(wait_for: [], &block) ⇒ Object

This method expects to wait for the parent TestPromise and then run a block of Ruby that returns another promise. This is useful for wrapping Promises like those from replace() that don’t have the test DSL built in. The block will execute when this outer promise is scheduled – so we don’t do a replace() too early, for instance. And then the outer promise will fulfill when the inner one does.
