Question

我试图为现有的Java EE应用程序编写集成测试，该应用程序使用Seam和Hibernate并部署到Glassfish。

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

非常感谢任何帮助......

这些可能是不必要的细节，但我使用JUnit（而不是TestNG）编写了测试，如here所述。该测试扩展了AbstractSeamTest，并具有实例化ComponentTest的@Test方法，并覆盖here所述的testComponents。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) {

        }
    }
}

你正在使用Witch Seam版本吗？

通常在某些依赖项无法注入组件时会发生此错误。 bean EmailService在测试用例中成功启动了吗？

为什么在JUnit测试尝试启动Seam时会抛出InstantiationException？
