PowerMockito期间方法过大错误

编程问答 2022-08-16

问题描述

此AWS lambda函数Java代码已编译，没有任何问题。但是，当使用powermockito执行单元测试时，将Main类添加到@PrepareForTest时便开始出现错误。 父方法调用了多种方法。 我尝试使用powermockito模拟一些方法。但是仍然获得方法大小超出异常。

Java代码 

Public class ClassA implements RequestHandler<InputPayLoadPojo,Response> {

        Public Response handleRequest(InputPayLoadPojo,Context) {
                Private ReturnType ChildMethod1()     {
               …..     
               }
                Private ReturnType ChildMethod2 ()    {
                       Private ReturnType SubChildMethod2 (){
                       ……..
                       }
               …..     
               }

                Public ReturnType ChildMethod1 ()     {
               …..     
               }

               .
               .
               .
               .

               Private ReturnType ChildMethod18 ()   {
               …..     
               }


        }

}

测试课程 

@RunWith(powermockrunner.class)
@PowerMockIgnore({ "javax.net.ssl.*","javax.management.*"})
@PrepareForTest({ ClassA.class})
public class SynchronousTest {

        ClassA obj = powermockito.spy(new ClassA());
@Test
public void testSynchronousTranslation() {

        doReturn(somevalue).when(obj,“ChildMethod1”,anyObject….);
        doReturn(somevalue).when(obj,“ChildMethod2”,“ChildMethod3”,anyObject….);

        obj.handleRequest(someInputPayLoadPojoObject,someContextObject);

}

}

遇到错误： 

java.lang.illegalaccessexception: Method was too large and after instrumentation exceeded JVM limit. PowerMock modified the method to allow JVM to load the class. You can use PowerMock API to suppress or mock this method behavIoUr.
