How to do the unit test of Spring Boot insert the data in the Bank?

I created a simple system that is working perfectly, but I need to implement a unit test in Spring Boot, which happens when I test or I can not enter the data in the database or it generates error;

I tried this way, did not generate error, but also failed to save in the database;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.projeto.subium.api.model.Project;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SubiumApplicationTests {



    @Test
    public void testAdicionarEmployee() throws Exception {
        Project project1 = new Project();
        String nome1 = new String("Google");
        project1.setName(nome1);


    }
}

Then I tried that way, but it caused an error, I updated the code;

   import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.projeto.subium.api.service.ProjectService;
import com.projeto.subium.api.model.Project;

@RunWith(SpringRunner.class)
@DataJpaTest
public class SubiumApplicationTests {

    @Autowired
    private ProjectService projectService;

    @Test
    public void testAdicionarEmployee(){
        Project project1 = new Project("Google");
        this.projectService.salvar(project1);
    }
}

What I need is to generate the test in such a way that it can save the data in the database.

This is the error message in the IDE;
