Create a Unit Test Suite

[gavination]

As a Developer, I want to validate the functionality of the code I write. To achieve this, I need a unit test suite defined and enabled across the system.

Acceptance Criteria:

• A Unit Test framework exists as a separate project in the repository (NUnit, for example)
• An initial set of Unit Tests are developed covering the Service and ViewModel layers, where applicable
• All external dependencies are mocked. (Example: when testing the ViewModel, the Services must be mocked, and vice versa)
• All tests must pass.

think I'll go with https://xunit.net/ as our testing suite of choice
