### Question:
AppEnvClusterService { public List<AppEnvCluster> findClusters(String env, long appId) { return appEnvClusterRepository.findByAppIdAndEnv(appId, env); }  List<AppEnvCluster> findClusters(String env, long appId); List<AppEnvCluster> findClusters(String env, String appCode); AppEnvCluster getAppEnvCluster(long appId, String env, String clusterName); void deleteAppEnvCluster(AppEnvCluster appEnvCluster); List<AppEnvCluster> createAppEnvCluster(CreateClusterReqDTO createClusterReqDTO);  }### Answer:
@Test public void findClusters() { String env = "dev"; long appId = 35l; List<AppEnvCluster> clusters = appEnvClusterService.findClusters(env, appId); }
