Using Moq and Unity together for testing

Moq lets you generate class (code) with prescribed behavior.

• Moq needs an interface
• Moq api is used to set the behavior of the generated class

Unity lets you resolve an interface to a concrete implementation.

• Register an interface with the desired concrete implementation
• The concrete implementation can be an instance of class generated by Moq for testing purposes
• In production, the interface is configured to resolve to real implementation classes
