Erro ao dar run na classe TesteCriaTabelas

Várias exceptions ocorreram ao executar a classe de teste duas coisas eu fiz diferente do instrutor que foram: colocar uma senha, mudar a porta para 3307 por ja ter a porta 3306 usada, depois que vi que era melhor sem senha a tirei pelo terminal do mariaDB.

meu persistance.xml:
