Question

我创建了我的第一批阅读器，我打算用mockito测试我的课程。我不知道该怎么做。您可以在下面找到我的课程＆＃34; Trailreader＆＃34;和我的测试班＆＃34; Trailreadertest＆＃34;我开始发展。我事先感谢你的帮助。

Trailreader类：

public class Trailreader implements ItemReader<TrailreaderInfo> {

    private static final Logger LOG = LoggerFactory.getLogger(Trailreader.class);
    private static final int LIMIT = 10;

    @Value("#{configurationBatch.limit}")
    public String limitString;

    public String tableName;
    public int nbLimit;
    public List<Long> listToDelete;

    @Inject
    @Named("trailDao")
    public transient ITrailDao trailDao;

    public Trailreader() {
        super();
    }

    /**
     * Initialize
     */
    @PostConstruct
    public void initialize() {

        try {
            nbLimit = Integer.parseInt(limitString);
        } catch (NumberFormatException e) {
            nbLimit = LIMIT;
        }
    }


    @DoNotLog
    @Transactional
    @Override
    public TrailreaderInfo read() throws Exception, UnexpectedInputException, NonTransientResourceException {
        try {
            List<String> tableList = trailDao.getTablesList();
            for (String tableName : tableList) {
                List<Long> list_id = trailDao.getlist_idByDate(tableName);
                List<Long> listToDelete = new ArrayList<Long>();
                if (list_id.size() > nbLimit) {
                    int list_id_size = list_id.size();
                    int j = 0;
                    while (list_id_size > nbLimit) {
                        listToDelete.add(list_id.get(j));
                        list_id_size--;
                        j++;
                    }
                }
            }
            return new TrailreaderInfo(tableName, nbLimit, listToDelete);
        } catch (Exception e) {
            LOG.error(e.getClass().getName(), e.getMessage());
            throw new ParseException(e.getMessage());
        }
    }
}

测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:test-applicationContext.xml" })
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
public class TrailreaderTest {
    private static final Logger LOG = LoggerFactory.getLogger(TrailreaderTest.class);

    @InjectMocks
    protected transient Trailreader reader;

    @Inject
    @Named("trailDao")
    protected transient ITrailDao trailDao;

    @Before
    public void setUp() throws Exception {
        LOG.info(TrailreaderTest.class.getSimpleName());
    }

    /**
     * Initialization method
     */
    @Transactional(value = Transactions.TX_MANAGER_READ_WRITE, readOnly = false)
    protected void initialization() {
        reader.trailDao = trailDao;
        reader.limitString = "10";
        reader.nbLimit = 10;

        reader.initialize();
    }

    @Test
    public void HistoryBackOfficeInfo() {
        initialization();   
    }   
}

如果你想测试你的ItemReader，那么你需要模拟它的依赖项而不是对象本身。

所以你需要嘲笑DAO。因此，在DAO返回空值或空列表或某些特定值的情况下，您可以测试阅读器......
