Interfaces as Boundaries (with C#, Mocks, TDD, and Fluent Assertions)

This time, I slow it down and demonstrate how to code boundaries using interfaces in C#. When we don't know what class or component will be used to implement an interface, we should still code to an expected interface. We own this interface and can trust it by using Test Driven Development and mock objects.
