为什么使用 SpringJUnit4ClassRunner.withAfterClasses 方法出现神秘的 MultipleFailureException 错误消息

Question

为什么我的 spring 测试设置失败并出现以下不太有用的错误消息？欢迎提出所有建议。

JUnit 输出

这里是目标sn-p

@Service 

public class PipApps {

@Resource( name = "apps" )
private Properties apps;

@Autowired
private SitePreferenceHandler sitePreferenceHandler;

@Autowired
private PipsTable pipsTable;

private SitePreference sitePreference;

private Device device;  

public PipApps( HttpServletRequest request, HttpServletResponse response ){
    sitePreference = sitePreferenceHandler.handleSitePreference( request, response );
    device = DeviceUtils.getRequiredCurrentDevice( request );
}

public Properties getApps(){
    return apps;
}

public Device getDevice(){
    return device;
}

public SitePreference getSitePreference(){
    return sitePreference;
}

public DeviceRouteTable getPipsTable(){
    return pipsTable;
}
}

还有测试sn-p

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration( locations={"src/test/resources/PipAppsTest-context.xml"} )

public class PipAppsTest {

@Mock
SitePreferenceHandler sitePreferenceHandler;

@Autowired
PipApps pipApps;

}

如果 JUnit 4.9 不在类路径中，Spring Framework 4.2.2 会引发更有意义的异常。详情请见SPR-13521。

以下是SpringJUnit4ClassRunner 的类级Javadoc 的摘录：

注意：从 Spring Framework 4.1 开始，此类需要 JUnit 4.9 或更高版本。

有问题的类 MultipleFailureException 是在 JUnit 4.9 中引入的。

这就是为什么您的测试使用 ClassNotFoundException 失败的原因。

因此升级到 JUnit 4.9（或最好是 4.12）将解决您的问题。
