A document or code for the system that we handover to the client for review/sign off is a deliverable.
But, this being a fully tested product, more or less, there is less scope for testing.

Thank you for your questions, and for your patience! Hopefully you will find our Adobe Target Implementation Product Documentation helpful. Please feel free to reach out with more specific questions as you explore this (deep) resource.
