如何对Spring存储库进行单元测试

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager;

import static org.assertj.core.api.Assertions.assertThat;

@DataJpaTest
public class RepositoryTest {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private UserRepository userRepository;

    @Test
    public void testSaveUser() {
        User user = new User("John Doe", "john.doe@example.com");
        User savedUser = userRepository.save(user);

        assertThat(savedUser.getId()).isNotNull();
        assertThat(savedUser.getName()).isEqualTo(user.getName());
        assertThat(savedUser.getEmail()).isEqualTo(user.getEmail());
    }

    @Test
    public void testFindUserByEmail() {
        User user = new User("John Doe", "john.doe@example.com");
        entityManager.persist(user);

        User foundUser = userRepository.findByEmail(user.getEmail());

        assertThat(foundUser).isEqualTo(user);
    }
}
