"expecting code to raise a throwable" erro ao gerar o testo no Junit

Programação Java

#1
  • o que eu to querendo testar é o método “save_throwConstraintViolationExcpetion_WhenTitleIsEmpty()”, ou seja, quando meu titulo for nulo, ele lançar uma exceção, mas o meu teste não está passando esse método. O que está errado?

classe de teste:

@DataJpaTest
@DisplayName("Classe de teste do ArticleService")
@Import(ArticleServiceImpl.class)
public class ArticleServiceTest {

@Autowired
private ArticleService articleService;

@Test
//nameMethod_expectedAct_state
void save_Persist_WhenSuccessful() {

	final Article result = articleService.save(new Article("article 1", "autor 1", LocalDate.of(1998, 05, 12),
			"O lorem ipsum é um texto bastante conhecido dos profissionais de design e editoração. Trata-se de um poema em latim, escrito por Cícero em 45 a.C, com as letras embaralhadas. É utilizado no mundo todo para preencher espaços em publicações antes da inserção do conteúdo real."));

	assertAll(
			() -> assertThat(result).isNotNull(),
			() -> assertThat(result.getAuthor()).isNotBlank(),
			() -> assertThat(result.getTitle()).isNotBlank(),
			() -> assertThat(result.getText()).isNotBlank(),
			() -> assertThat(result.getDate()).asInstanceOf(InstanceOfAssertFactories.LOCAL_DATE));
}

@Test
void save_throwConstraintViolationExcpetion_WhenTitleIsEmpty() {
	Article obj = new Article(null, "autor 1", LocalDate.of(1998, 05, 12),
			"O lorem ipsum é um texto bastante conhecido dos profissionais de design e editoração. Trata-se de um poema em latim, escrito por Cícero em 45 a.C, com as letras embaralhadas. É utilizado no mundo todo para preencher espaços em publicações antes da inserção do conteúdo real.");
	articleService.save(obj);		
			
	 assertThatExceptionOfType(ConstraintViolationException.class)
	 .isThrownBy(() -> articleService.save(obj))
	 .withMessageContaining("O nome do título não pode ser vazio!");
}	
}

atributos da classe entity:

@Entity
public class Article {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

@NotBlank
private String title;

@NotBlank
private String author;

private LocalDate date;

@NotBlank
@Size(min = 201)
@Lob
private String text;

Precisa postar mais detalhes do erro.

#3

Apenas criar a instância não vai executar as validações do BeansValidation. Para validar, vc deve fazer assim depois de criar a instância:

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
Set<ConstraintViolation<Article>> violations = validator.validate(article);

Se o set vier preenchido, significa que alguma validação não passou.

#4

amigo, nao entendi muito bem. onde eu colocaria esse trecho de código? depois que criar a instancia do meu Article e salva-lo no banco de dados? e qual assert eu uso?

aparece isso aqui

#6

Não, após instanciar, você valida a instância com o Validator, conforme o @Lucas_Camara mostrou.

#7

entendi. E depois disso eu uso qual assert? como eu poderia usar essa variável “violations” ?

#8

O Set<ConstraintViolation<Article>> violations vai retornar tudo que não passou na validação. Basta vc verificar cada item do Set. Se me lembro, vc consegue pegar a mensagem gerada em cada validação.
