Assert multiple field error codes from Validation using MockMvc

Question

I am trying to assert two errors due to two given constraints to my form. My form has two constraints on its single field:

@Data
@NoArgsConstructor
@NotExistingGroup(groups = SecondGroupValidation.class)
public class GroupForm {

  @NotBlank(groups = FirstGroupValidation.class)
  @Size(min = 2, max = 30, groups = FirstGroupValidation.class)
  private String name;
}

With the following test, I want to trigger both the @NotBlank and @Size validation and assert both raised errors:

@Test
void givenGroupEmptyName_groupPost_assertErrors() throws Exception {

  mvc.perform(post("/groups/add").param("name", ""))
      .andDo(print())
      .andExpect(status().isOk())
      .andExpect(view().name("groups-add"))
      .andExpect(model().hasErrors())
      .andExpect(model().attributeErrorCount("groupForm", 2))
      .andExpect(model().attributeHasFieldErrorCode("groupForm", "name", "NotBlank"))
      .andExpect(model().attributeHasFieldErrorCode("groupForm", "name", "Size"));
}

The mvc doPrint() method shows both errors are given

ModelAndView:
        View name = groups-add
             View = null
        Attribute = groupForm
            value = GroupForm(name=)
           errors = [Field error in object 'groupForm' on field 'name': rejected value []; codes [NotBlank.groupForm.name,NotBlank.name,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [groupForm.name,name]; arguments []; default message [name]]; default message [must not be blank], Field error in object 'groupForm' on field 'name': rejected value []; codes [Size.groupForm.name,Size.name,Size.java.lang.String,Size]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [groupForm.name,name]; arguments []; default message [name],30,2]; default message [size must be between 2 and 30]]

However, the test breaks with the following error

java.lang.AssertionError: Field error code expected:<Size> but was:<NotBlank>
