spring集成测试给定/When/Then Java

Question

我想为我的服务方法编写一个集成测试，但我在这方面有一些问题。我还有其他一些测试，我想像模式一样使用，但对我来说还是太难了，因为在这个方法中，我有不同类型的返回元素： 这是我的方法：

public List<PersonWithTeamsDto> peopelWithTeamsAssigned() {
        List<Person> people = personRepository.findByTeamsNotEmpty();

        return people.stream()
                .map(person -> {
                    PersonWithTeamsDto dto = modelMapper.map(person, PersonWithTeamsDto.class);
                    dto.setTeams(mapTeams(person));
                    return dto;
                }).collect(Collectors.toList());
    }

我想测试一下这个方法！！ 我想这样做：

public void shouldAddPersonToTeam() {

        // Given
        TeamDto teamDto = new TeamDto(null, "Janek", "local", "wawa", 6);
        PersonDto personDto = new PersonDto(null, "janek", "mucha", "email1@onet.com", "krakow", "Programing", "Developer");
        Team team = teamService.createTeam(teamDto);
        Person person = personService.addPerson(personDto);

        // When
        final long personId = person.getId();
        teamService.addPersonsToTeams(team.getId(), personId);

        entityManager.flush();
        entityManager.clear();
        // Then
        Optional<Team> teamFromService = teamService.findTeamEntityById(team.getId());
        assertThat(teamFromService.isPresent()).isTrue();
        Set<Person> persons = teamFromService.get().getPersons();
        assertThat(persons).hasSize(1);
        assertThat(persons.stream().filter(person1 -> person1.getId() == personId).findAny()).isPresent();
    }

但实际上我有一个：

@Test
    @Transactional
    public void shouldReturnPeopleWithTeamsAssigned(){

        // Given
        TeamDto teamDto = new TeamDto(null, "Janek", "local", "wawa", 6);
        PersonDto personDto = new PersonDto(null, "janek", "mucha", "email1@onet.com", "krakow", "Programing", "Developer");
        Team team = teamService.createTeam(teamDto);
        Person person = personService.addPerson(personDto);

        //When
        teamService.addPersonsToTeams(team.getId(),person.getId());
        personService.peopelWithTeamsAssigned();

        entityManager.flush();
        entityManager.clear();
        //Then
        List<PersonWithTeamsDto> personWithTeamsDtos = personService.peopelWithTeamsAssigned();
        assertThat(personWithTeamsDtos.contains();

    }
