模擬對象在我訪問公共方法時工作正常。但是當(dāng)我訪問私有方法時它不起作用。我的模擬課：@componentpublic class Test{public List<String> list(){ // some function}}我的主類：@componentpublic class Test2{private string method(String method){//here where i have to use mock object//some function}}我的測試用例：public class JunitTestCases{@MockTest test;@Autowired@InjectMocksTest2 test2public void Oncall{Test2 test=new Test2();Method method=Test2.class.getDeclaredMethod("method",String.class);method.setAccessible(true);method.invoke(test, "data");}}我得到以下錯誤。java.lang.reflect.InvocationTargetExceptionat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at com.TestCases.method(TestClass.java:198)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50)at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12)任何建議？我怎樣才能讓它工作？
