Hi! Sincerely I don't even think there are unit tests written for this kind of code since it involves asserts from static methods and things that can not be mocked, but I may be wrong also. I am at the beginning with developments on the Steem blockchain, so I am still getting used with the project.

From my experience with other projects (from which I had worked on a few with more than 90% code coverage) I don't think that this method was ever designed to be tested within a unit test. Maybe a set of integration tests would do the job, but I am not that sure about them also.

Thanks so much for the review!
