java.lang.NoSuchMethodError: org.mockito.Mockito.framework()Lorg/mockito/MockitoFramework

Question

I've been facing a peculiar problem. Basically, when I run my Mockito test normally i.e. 'Run as Junit Test', it gives me the following error. Can someone help me please what is my mistake?

The error received:

    java.lang.NoSuchMethodError: org.mockito.Mockito.framework()Lorg/mockito/MockitoFramework;

The test class:

public class ListTest {
    @Test
    public void letsMockListSize() {
        List<?> list= mock(List.class);
        when(list.size()).thenReturn(2);
        assertEquals(2, list.size());
    }
}

Answer 1

The sample works if you remove the PowerMock dependencies. The issue is that the versions of Mockito and PowerMock used are incompatible with each other. For PowerMock 2.x you need at least Mockito 2.8.9+. PowerMock provides a compatibility list that shows what version of PowerMock is compatible with what version of Mockito. Fix up the versions to be compatible with each other and your sample will start to work.

Answer 2

I was getting a similar issue, when trying to use Mockito with Junit 5 (@ExtendWith)

java.lang.NoSuchMethodError: org.mockito.Mockito.mockitoSession()Lorg/mockito/session/MockitoSessionBuilder;

This was coming as there were two versions of mockito present in the classpath (one is mockito-all and another is mockito-core), through transitive dependency. After removing the mockito-all dependency from POM explicitly, the issue got resolved.

@ExtendWith(MockitoExtension.class)
public class TodoBusinessImplWIthMockWithAnnotationTest {

   @Mock
   TodoService todoService;

   @Test
   public void usingMockito() {

    ......

   }

}
