Mock redis template

I am facing a issue in mock redis template.Can any one help me to write unit test for below class.

@Repositorypublic class CasheRepo {    @Autowired    private RedisTemplate<String, Object> template;    public Object getObject(final String key) {    return template.opsForValue().get(key);    }}

And below is unit test class. But it is not working. It shows null point exceptions

@RunWith(MockitoJUnitRunner.class)public class CashRepoTest {    @InjectMocks    private CasheRepo casheRepo = new CasheRepo();    private @Mock RedisConnection redisConnectionMock;    private @Mock RedisConnectionFactory redisConnectionFactoryMock;    private RedisTemplate redisTemplate;    @Before    public void setUp() {   Mockito.when(redisConnectionFactoryMock.getConnection()).thenReturn(redisConnectionMock);       redisTemplate = new RedisTemplate();    redisTemplate.setConnectionFactory(redisConnectionFactoryMock);    redisTemplate.afterPropertiesSet();    }    @Test    public void getObjectTest() {    Mockito.doNothing().when(redisTemplate).opsForValue().set("spring", "data");    redisTemplate.afterPropertiesSet();      System.out.println(redisTemplate.opsForValue().get("spring"));       }    }
