This is because the MockitoRule is not initialized in the test class. We can fix this by using the MockitoJUnit.rule() method as shown in the following code:26import org.junit.Rule;27import org.junit.Test;28import org.junit.runner.RunWith;29import org.mockito.Mock;30import org.mockito.junit.MockitoJUnit;31import org.mockito.junit.MockitoRule;32import org.mockitousage.IMethods;33import org.mockitoutil.TestBase;34import static org.junit.Assert.assertEquals;35import static org.junit.Assert.assertNotNull;36import static org.mockito.Mockito.when;37@RunWith(MockitoJUnit.SilentRunner.class)38public class SilentRunnerTest extends TestBase {39    @Rule public MockitoRule mockitoRule = MockitoJUnit.rule();40    @Mock IMethods mock;41    public void shouldInitializeMocks() {42        assertNotNull(mock);43    }44    public void shouldInitializeMocks2() {45        when(mock.simpleMethod()).thenReturn("foo");46        assertEquals("foo", mock.simpleMethod());47    }48}
