• [ ] src/test/java/org/trebol/jpa/services/conversion/BillingCompaniesConverterJpaServiceImplTest - In method testApplyChangesToExistingEntity there needs to be a better assertion. This also applies to these services

  • [ ] src/test/java/org/trebol/jpa/services/conversion/BillingTypesConverterJpaServiceImplTest
  • [ ] src/test/java/org/trebol/jpa/services/conversion/SellStatusesConverterJpaServiceImplTest
  • [ ] src/test/java/org/trebol/jpa/services/conversion/ShippersConverterJpaServiceImplTest
  • [ ] src/test/java/org/trebol/jpa/services/conversion/UserRolesConverterJpaServiceImplTest

These issues are no longer present, so I'm closing this.
