AssertionError em teste de autenticação com dados válidos

Oi Gabriela,

Acho que o problema está no seu json:

String json = "{\"email\"=\"aluno@email.com\", \"senha\"=\"123456\"}";

Está com símbolo de = ao invés de :

String json = "{\"email\":\"aluno@email.com\", \"senha\":\"123456\"}";

Olá, professor!

Fiz o teste com o json certo agora, porém deu o mesmo erro.

@Test
    public void autenticar_withAValidEmail_mustReturn200() throws Exception {
        URI uri = new URI("/auth");
      String json = "{\"email\":\"aluno@email.com\", \"senha\":\"123456\"}";

        mockMvc.perform(MockMvcRequestBuilders
                        .post(uri)
                        .content(json)
                        .contentType(org.springframework.http.MediaType.APPLICATION_JSON))
                .andExpect(MockMvcResultMatchers
                        .status()
                        .is(200));
    }

Segue o erro que aparece no terminal:

      HTTP Method = POST
      Request URI = /auth

Minha função de autenticar no controller:

@RestController
@RequestMapping("/auth")
@Profile(value = {"prod", "test"})
public class AutenticacaoController {

    @Autowired
    private AuthenticationManager authManager;

    @Autowired
    private TokenService tokenService;

    @PostMapping
    public ResponseEntity<TokenDto> autenticar(@RequestBody @Valid LoginForm form) {
        UsernamePasswordAuthenticationToken dadosLogin = form.converter();

        try {
            Authentication authentication = authManager.authenticate(dadosLogin);
            String token = tokenService.gerarToken(authentication);
            return ResponseEntity.ok(new TokenDto(token, "Bearer"));
        } catch (AuthenticationException e) {
            return ResponseEntity.badRequest().build();
        }
    }
}

Oi Gabriela,

Coloca essa linha no seu catch do método no controller:

} catch (AuthenticationException e) {
    e.printStacktrace();
    return ResponseEntity.badRequest().build();
}

E depois que rodar o teste veja no console qual erro está ocorrendo.
