Remova essa anotação da classe: @AutoConfigureWebMvc, pois nos testes de repository ela não deve ser utilizada.

tirei, mas o erro persiste

achei o erro não sei porque o motivo disso, mas tirei a anotação @DataJpaTest. ficou assim eu pesquisei um pouco sobre essa anotação mas não está claro ainda o porque.

@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE) @SpringBootTest class AlunoRepositoryTest {

@Autowired
private AlunoRepository alunoRepository;


@Test
void DeveriaProcurarPeloNome() {
    String nome = "nomeAluno";
    Aluno aluno = alunoRepository.findByNome(nome);

    assertNotNull(aluno);
    assertEquals(nome,aluno.getNome());
}

}
