Spring java Oracle get test

I try to test my connection to database, when I try to use query in IntelliJ IDEA IDE it works, but unit test failed. I just starting with java, so I probably do something wrong, can you say me how to do it right? I try to test, if I get all values from table Workers and second test is if I get one special value from table Workers.

Worker model class:

    package com.bmp.bmp.model;

import javax.persistence.*;

@Entity
@Table(name = "WORKERS")
public class Workers {

  @Id
  @Column(name = "WORKER_ID")
  private int workerId;
  @Column(name = "FIRSTNAME")
  private String firstname;
  @Column(name = "LASTNAME")
  private String lastname;
  @Column(name = "WORKPLACE_ID")
  private int workplaceId;

  public Workers(int workerId, String firstname, String lastname, int workplaceId)
  {
      super();
      this.workplaceId = workplaceId;
      this.lastname = lastname;
      this.firstname = firstname;
      this.workerId = workerId;
  }
  public Workers()
  {
      super();
  }

  public int getWorkerId() {
    return workerId;
  }

  public void setWorkerId(int workerId) {
    this.workerId = workerId;
  }


  public String getFirstname() {
    return firstname;
  }

  public void setFirstname(String firstname) {
    this.firstname = firstname;
  }


  public String getLastname() {
    return lastname;
  }

  public void setLastname(String lastname) {
    this.lastname = lastname;
  }


  public int getWorkplaceId() {
    return workplaceId;
  }

  public void setWorkplaceId(int workplaceId) { this.workplaceId = workplaceId;
  }

}
