伙计 问题： 如何模拟定义了其他静态final类的静态final类？java.lang.NoSuchMethodError powermock
问题描述： 当我想为最后一个类ApplianceRelationshipUtils.java编写一些单元测试用例，并且在这个最终的类ApplianceRelationshipUtils.java中时，总是会调用另一个静态类ApplianceUtilities.java。所以，我需要使用powermock嘲笑静态类ApplianceUtilities.java这样的：
// mock the class for one method only
PowerMock.mockStaticPartialNice(ApplianceUtilities.class,"getApplianceVersion");
但在ApplianceUtilities.java定义了很多静态最终班组长这样的：
private static final IMesUtils m_mesUtils = new MesUtils();
private static final IEndpointUtilities m_endpointUtils = new DefaultEndpointUtilities(m_mesUtils);
private static final ICasUtilities m_casUtils = new DefaultCasUtilities(m_endpointUtils);
private static final IHAApplianceUtilities m_haUtils = new HAApplianceUtils(m_endpointUtils, m_casUtils);
所以，当我运行testcase会抛出一些异常，如下所示：
java.lang.NoSuchMethodError: com.ibm.usmi.services.updates.util.RestartUtilities.<init>(Lcom/ibm/usmi/services/updates/util/IRcsUtilities;Lcom/ibm/usmi/services/updates/util/MesUtils;Lcom/ibm/usmi/services/updates/util/IUpdateUtils;)V

您正在使用哪种PowerMock捆绑包？正如本页所引用的：http://code.google.com/p/powermock/wiki/GettingStarted – Magnilex 2013-03-27 08:45:45
