I created a simple system that is working perfectly, but I need to implement a unit test in Spring Boot, which happens that when I perform the test or I cannot enter the data in the database or generates error;
I tried this way, it did not generate error, but also failed to save in the bank;
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 this way, but it got 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;

Your first way didn’t save in the bank because you just arrow the name, don’t call any rescue method. In the second form, you call, but you need to know the error that gives. Could edit your question and include the stacktrace of this error?
– StatelessDev
@Statelessdev I reedited the question and put the error picture, could I have a look please.

i did an update on the entire post, so I would like you to read from the top, please.

This test will not work, since there is a container dependency running to perform transactions to the database, if it runs you cannot use the service methods as well, because of the injection. I would advise you to create a unit test so that you test, only the save() method, things like business rules for example, save itself, you can create a mock to return something by simulating a transaction with the database.
