Add: Add tests for "name" and "comment" field validations

Implement the first gsad unit tests for checking the "name" and "comment
field validation. The tests are implemented using cgreen and will be
configured if the cmake variable BUILD_TESTING is set. Calling `make
tests` will build the tests and `make test` will run them.
