Testing @ConfigurationProperties with Mockito

I have configuration class:

@ConfigurationProperties(prefix = "myConfig")
public class MyConfig {
    protected String config;
}

My service uses this config class and I'm trying to test it with Mockito:

@RunWith(MockitoJUnitRunner.class)
public class myTest {

    @InjectMocks
    private MyService myService;

    @Mock
    private MyConfig myConfig;

    @Test
    public void myTest1() {
        myService.getInfo("a");
    }
}

myTest fails since the config class is mocked, thus has null values. What is the right way to test configuration class with Mockito?
