为什么JUnit测试试图启动Seam时会引发InstantiationException？

Question

我正在尝试为现有的Java EE应用程序编写集成测试，该应用程序使用Seam和Hibernate并将其部署到Glassfish。

但是测试目前无法在一开始就启动Seam。这似乎是因为它不能实例化Quartz Scheduler组件 - 请参阅下面的代码。异常堆栈跟踪也在下面。

任何帮助，将不胜感激......

这些可能是不必要的细节，但我写的描述here使用JUnit（而不是TestNG的）测试。该测试扩展了AbstractSeamT​​est，并具有@Test方法，用于实例化ComponentTest并覆盖testComponents，如here所述。在Maven的预集成阶段使用Cargo将应用程序部署到现有的本地Glassfish实例，并使用Failsafe插件运行测试。

InitialiseQuartz类 ：

@Name("initialiseQuartz") 
@Scope(ScopeType.APPLICATION) 
@Startup 
public class InitialiseQuartz { 

    private QuartzTriggerHandle qth; 

    @In(create=true) 
    private EmailService emailService; 

    @Create 
    public void startSchedule() { 
     System.out.print("Schedule started"); 
     qth = emailService.generateDailyEmail("0 0 7 * * ?"); 
    } 

    @Destroy 
    public void stopSchedule() { 
     try { 
      qth.cancel(); 
     } catch (SchedulerException se) { 

     } 
    } 
}

女巫缝版本您使用的？

此错误通常发生在某些依赖项无法注入到组件中时。 Bean EmailService在您的测试用例中成功启动？
