我正在使用带有嵌入式 Glassfish 4.0 容器的 Arquillian 进行测试。到目前为止，我设法让它工作，但是一个测试用例一直失败，我不知道为什么。这是我的测试代码：

// Test Class
    @Inject
    private CompetenceService competenceService;

    @Test
    public void createSingleCompetence() {
        Competence c = new Competence();
        // fill the competence with data
        c = competenceService.save(c); // throws a RollbackException
        // some testing assertions
    }

这是服务类：

// CompetenceService
@Transactional
@ApplicationScoped
public class CompetenceService {

    @PersistenceContext
    private EntityManager em;

    public Competence save(Competence c){
        return em.merge(c);
    }
}

使用 arquillian 运行此程序时，会出现以下错误：

 Managed bean with Transactional annotation and TxType of REQUIRED encountered exception during commit javax.transaction.RollbackException: Transaction marked for rollback

我的问题是：我能以某种方式找出问题所在吗？我的第一个想法是并非所有约束都得到满足（如@NotNull），但我现在排除了这一点。

我没有得到完整的堆栈跟踪，只有测试运行结束时的错误。这是输出：

这不是 Arquillian 的问题。

由于您在 StackTrace 中找不到异常，我想原始异常被包装到 RollbackException 中。根据 JTA 1.2 规范，任何未经检查的异常都会自动回滚事务。

您能否确认在您的任何底层方法中都没有抛出未经检查的异常（例如 RuntimeException、Nullpointer 等） - 甚至可能来自某些自定义验证器。这是供进一步参考的 JTA 1.2 规范：https ://java.net/projects/jta-spec/sources/spec-source-repository/content/jta-1_2-spec_v2.pdf?rev=14
