The document summarizes a talk about Bow, which is a behavior-driven development (BDD) framework for Arrow. It discusses the evolutions of development approaches, provides an overview of what Bow is and how it works, demonstrates examples of using Bow with Node.js and web integration, and outlines next steps to become a BDD master with practice using the right tools.

14. BDD – Stakeholder Stories
In order to
<achieve some outcome which contributes to the
vision, or business value>
As a
<stakeholder>
I want
<some other stakeholder>
<to do, use or be restricted by something>

15. BDD – Story or Unit tests?
 What’s the difference between story and unit tests where I have
both?
The difference is that the story checks the
whole, but I might wish to confirm a portion of the
whole
and that is when I need a unit test.
