我有一个数据源,我可以从中请求一个(任何)国家/地区的人员列表,以及一个从该数据源检索人员并按字母顺序按名称对其进行排序的方法.我应该如何编写单元测试以确保我的方法的排序部分正常工作？

这就是我的SUT的样子:

class PeopleStuff {

    public IData data;

    public List<Person> getSortedPeopleForCountry(String countryName) {
        List<Person> people = data.getPeopleForCountry(countryName);

        Comparator nameComparator = new PersonNameComparator();
        Collections.sort(people, nameComparator);

        return people;
    }

}

这就是我的单元测试的样子:

@Test public void testGetPeopleSortsByPeopleName() {
    String COUNTRY = "Whatistan";

    // set up test (the 3 lines below are actually in a @Before setup method)
    PeopleStuff peopleStuff = new PeopleStuff();
    IData mockData = createNiceMock(IData.class);
    peopleStuff.data = mockData;

    // set up data
    List<PersonName> mockPeopleList = new ArrayList<PersonName>();
    mockPeopleList.add(new Person(COUNTRY, "A"));
    mockPeopleList.add(new Person(COUNTRY, "D")); …
