@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
@Value annotations working on spring junit test, annotation ONLY config. no xml Raw
@Configuration
@ComponentScan("dan.langford")
static class someConfig {

  // because @PropertySource doesnt work in annotation only land
  @Bean
  PropertyPlaceholderConfigurer propConfig() {
    PropertyPlaceholderConfigurer ppc =  new PropertyPlaceholderConfigurer();
    ppc.setLocation(new ClassPathResource("some.properties"));
    return ppc;
  }
}

@PropertySource("classpath:${APP_ENV:default}.properties")

Your use of @Value requires a PropertySourcesPlaceholderConfigurer bean to resolve ${...}placeholders. 

@Configuration
public class PropertyTestConfiguration {
    @Bean
    public PropertyPlaceholderConfigurer propertyPlaceholderConfigurer() throws IOException {
        final PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
        ppc.setLocations(ArrayUtils.addAll(
                        new PathMatchingResourcePatternResolver().getResources("classpath*:application.properties"),
                        new PathMatchingResourcePatternResolver().getResources("classpath*:test.properties")
                )
        );

        return ppc;
    }

}
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
public class PropertyTests {
    @Value("${elastic.index}")
    String index;

    @Configuration
    @Import({PropertyTestConfiguration.class})
    static class ContextConfiguration {
    }
}
