/**
 * Created by steve on 03/02/17.
 *
 * These test cases are commented out as they can only be executed one at a time
 * as they are depending on manipulating server.json in home directory. It executed
 * in mvn clean install, all tests will be started at the same time and they will
 * use the same server.json and cause "address in use error".
