Ajuda para criar um classe teste

Bom dia estou precisando muito de ajuda sobre Teste Unitário no Intellij.

Estou desenvolvendo a classe Entities e não estou sabendo criar um teste unitário dessa classe, alguém pode me ajudar.


@Entity
@Table(name = "INFO_REG_ARQ_RECBD", schema = "GRLF")
public class InfoRegEntity implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "NUM_REG", columnDefinition = "NUMBER(10,0)", nullable = false)
private Long registerNumber;

@Column(name = "ID_GRP", columnDefinition = "NUMBER", nullable = false)
private Long groupId;

@Column(name = "ID_TRANS", columnDefinition = "NUMBER", nullable = false)
private Long transactionId;

@Column(name = "NUM_ARQ_RECBD", columnDefinition = "NUMBER(10,0)", nullable = false)
private Long fileNumberReceived;

@Column(name = "ID_SIT", columnDefinition = "NUMBER", nullable = false)
private Long situationId;

@Column(name = "HOR_ALT_REG", columnDefinition = "VARCHAR2(70 CHAR)", nullable = true)
private LocalDateTime recordChangeTime;

@Column(name = "COD_USUAR_ALT_REG", columnDefinition = "VARCHAR2(50 CHAR)", nullable = true)
private String registrationChangeUser;

@Column(name = "DES_CONTD_REG", columnDefinition = "VARCHAR2(4000 CHAR)", nullable = false)
private String receivedContent;

@Column(name = "UUID", columnDefinition = "VARCHAR2(36 CHAR)", nullable = true)
private String uuId;

@Column(name = "DES_MOTVO", columnDefinition = "VARCHAR2(100 CHAR)", nullable = true)
private String reasonDescription;

public InfoRegEntity() {
