* Introduce mocking framework and increase coverage (#22) This change introduces two common golang patterns: - types: this will allow fine-tuned control over imported types by defining where they will be used and how - mock: this allows the generation of mock constructors, which allows for testing any individual path in a method by "injecting" a mock method which matches the expected type This change also increases test coverage to 100% Co-authored-by: Yoshiyuki Mineo <Yoshiyuki.Mineo@jp.sony.com> * gofmt --------- Co-authored-by: Bradley Boutcher <btboutcher@icloud.com>
