Question

测试方法有问题。我有restcotroller，我想测试删除方法（选项 - 不应该从数据库中删除对象）。这是我在服务类中的方法：

public Optional<PersonDto> deletePerson(Long id) {
        Assert.notNull(id, "id can't be null");
        Optional<Person> personOptional = personRepository.findById(id);
        personRepository.deleteById(id);
        return personOptional.map(p -> modelMapper.map(p, PersonDto.class));
    }

这是我有问题的测试方法：

@Test
public void shouldNotDeletePersonByGivenId() throws Exception {
    Mockito.doThrow(new NoEntityFoundException()).when(personService).deletePerson(1L);
    mockMvc.perform(delete("/people/{id}", 1L))
            .andExpect(status().isBadRequest());
}

此测试中的错误是：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.softwaremind.crew.people.service.NoEntityFoundException: There is no Entity in database with this id.

异常类：

public class NoEntityFoundException extends RuntimeException {
    public NoEntityFoundException() {
        super("There is no Entity in database with this id.");
    }
}

尝试将@Test注释更改为@Test(expected=NoEntityFoundException.class)

测试mockito junit方法不起作用
