捕获异常后java代码失败

Question

我正在为我的服务类编写一个单元测试。 我还想测试无法工作的案例，然后捕获异常并继续。但是如果我尝试这个，测试总是失败

    @Before
public void intial() {
    a = new Article();
    a.setName("stock test article");
    articleService.save(a);
    create = new StorageLocation();
    create.setCarlaStorageId(-4636L);
    storageLocationService.save(create);
}

/**
 * Test of save method, of class StockService.
 */
@Test
public void testSave() {
    System.out.println("save");
    Stock save = new Stock();

    // if i do this the test fails, but why ?
//        try {
//            instance.save(save);
//            fail("saved stock without article");
//        } catch (Exception e) {
//            // correct
//            System.out.println("unable to save without article.");
//        }

    save.setArticle(a);
    save.setCntStock(6);
    save.setOldStock(2);

    // if i do this the test fails, but why ?
//        
//        try {
//            instance.save(save);
//            fail("saved stock without storagelocation");
//        } catch (Exception e) {
//            // correct
//            System.out.println("unable to save without storagelocation.");
//        }

    save.setStorageLocation(this.create);
    save.setLastModify(new Timestamp(System.currentTimeMillis()));
    instance.save(save);
}

@After
public void cleanUp() {
    this.storageLocationService.delteLocation(create);
}

保存方法

    public void save(final Stock save) {

    try (StatelessSession session = this.hibernateFactory.openStatelessSession()) {
        Transaction beginTransaction = session.beginTransaction();
        beginTransaction.begin();
        if (save.getId() != null) {
            session.update(save);
        } else {
            session.insert(save);
        }
        save.getArticle().setEdited(true);
        session.update(save.getArticle());
        beginTransaction.commit();
    } catch (Exception e) {
        save.setId(null);
        throw e;
    }
}

错误消息：
