Question

我正在使用IntelliJ下运行的TestNg测试hibernate。我在套件中有两个测试，当套件运行时，其中一个失败。当我单独运行它们时它们会成功。此外，当我点击“仅运行失败”时，我会变绿。

我猜测试的主体在这种情况下并不重要，但无论如何我都在这里提出。 Stacktrace在下面。

我尝试将singleThreaded参数添加到测试套件中，但这没有帮助。我还添加了AfterMethod，我认为应该有所帮助，但结果是一样的。有什么想法正在发生什么？

@Test(singleThreaded = true)
public class RatesPersistanceTest
{
private SessionFactory sessionFactory;

@BeforeMethod
private void before() throws Exception
{
    sessionFactory = new Configuration().configure().buildSessionFactory();
}

@AfterMethod
private void after() throws Exception
{
    sessionFactory.close();
}

@Test
public void should_save_rates_and_retrieve_them_with_success()
{
    Money standardPrice = Money.parse("USD 85");
    Money upchargeExtraPerson = Money.parse("USD 80");
    Money upchargeExtraBed = Money.parse("USD 75");
    Room room = getMeRoom();

    AvailabilityPeriod availabilityPeriod = new AvailabilityPeriod(DateTime.now(), DateTime.now().plusDays(5), true);
    Season season = new BasicSeason("season name", availabilityPeriod);
    Rate seasonRate = new SeasonRate(standardPrice, upchargeExtraPerson, upchargeExtraBed, room, season);

    Session session = sessionFactory.openSession();
    session.beginTransaction();

    session.save(room);

    session.save(season);

    session.save(seasonRate);

    session.getTransaction().commit();
    session.close();
}

@Test(expectedExceptions = org.hibernate.exception.ConstraintViolationException.class)
public void season_rate_should_violate_db_constraints_when_saved_without_season()
{
    Money standardPrice = Money.parse("USD 85");
    Money upchargeExtraPerson = Money.parse("USD 80");
    Money upchargeExtraBed = Money.parse("USD 75");
    Room room = getMeRoom();

    AvailabilityPeriod availabilityPeriod = new AvailabilityPeriod(DateTime.now(), DateTime.now().plusDays(5), true);
    Season season = new BasicSeason("season name", availabilityPeriod);
    Rate seasonRate = new SeasonRate(standardPrice, upchargeExtraPerson, upchargeExtraBed, room, null);

    Session session = sessionFactory.openSession();
    session.beginTransaction();

    session.save(room);

    session.save(season);

    session.save(seasonRate);

    session.getTransaction().commit();
    session.close();
}


private Room getMeRoom()
{
    final RoomName roomName = new RoomName("101");
    final RoomType roomType = new RoomType("cheap");
    final Money standardPrice = Money.parse("USD 100");
    final Money upchargeExtraPerson = Money.parse("USD 50");
    final Money upchargeExtraBed = Money.parse("USD 20");
    final RackRate rackRate = new RackRate(standardPrice, upchargeExtraPerson, upchargeExtraBed, null);
    final int maxExtraBeds = 2;
    final Occupancy occupancy = new Occupancy(4, 2);
    return new Room("C", roomName, roomType, rackRate, HousekeepingStatus.CLEAN, RoomAvailability.AVAILABLE, maxExtraBeds, occupancy);
}

}

Answer 1

我回到那个项目，问题也回来了。

解决方案如下：

将@BeforeMethod和@AfterMethod更改为@BeforeSuite和@AfterSuite

这也意味着在一个测试中插入的数据将在另一个测试中可见，至少我认为如果我不在测试之间放下hibernate就是这种情况，但这至少有效，所以我可以处理它。

使用TestNg测试hibernate，测试在单独运行时传递但在套件中失败
