在下面的类中，我有匿名的内部类，因此如何使用嘲讽对其进行测试。请检查以下代码

// Service class
@Component("someServiceclass")
public class SomeServiceclassImpl implements SomeServiceclass {

 @Autowired
 RepoClass repo;

 LoadingCache < String,ClientDetails > clientDetailsCache = 
CacheBuilder.newBuilder()
  .build(new CacheLoader < String,ClientDetails > () {
   @Override
   public ClientDetails load(String clientId) throws Exception {

    OauthClientMapping client = repo.findByClientId(clientId);

    return someObject;
   }
  });

 @Override
 public void method(String id) {
  String param = request.getParameter("param");
 }
}
