NoClassDefFoundError for MockitoInvocationHandler class
java, junit4, mockito, powermock
Solution
Mockito 1.9.5-rc1 had to be refactored internally to allow third party mock maker. `MockitoInvocationHandler` was part of the Mockito's internals (as the package name suggests) up to Mockito 1.9.0.
Due to these changes, current some older version Powermock releases as of today are not compatible with the latest Mockito release.
Another reason to avoid mocking/stubbing finals or statics ;)
Hope that helps Cheers,
Problem
I am using `mockito-all-1.9.5-rc1.jar` and `powermock-mockito-1.4.12-full.jar`. When I run this simple unit test for mocking final method in non-final class. ``` import static org.junit.Assert.assertEquals; import org.junit.Test; import org.junit.runner.RunWith; import org.powermock.api.mockito.PowerMockito; import org.powermock.core.classloader.annotations.PrepareForTest; import org.powermock.modules.junit4.PowerMockRunner; @RunWith(PowerMockRunner.class) @PrepareForTest(ABC.class) public class ABCTest { @Test public void finalCouldBeMock() { final ABC abc = PowerMockito.mock(ABC.class); PowerMockito.when(abc.myMethod()).thenReturn("toto"); assertEquals("toto", abc.myMethod()); } } ``` When I ran it, I got `java.lang.NoClassDefFoundError: org/mockito/internal/MockitoInvocationHandler Caused by: java.lang.ClassNotFoundException: org.mockito.internal.MockitoInvocationHandler` When I search fo class `MockitoInvocationHandler` in `mockito-all-1.9.5-rc1.jar` and `powermock-mockito-1.4.12-full.jar`. I couldn't find any. Need help with this issue! Thank you
