我在杀死一些突变方面有点困难，我不明白为什么。
这是我正在测试的类

@Configuration
@EnableScheduling
public class TasksDeclaration {

  private static final Logger LOGGER = LoggerFactory.getLogger(TasksDeclaration.class);

  private final ErrorLogFactory errorLogFactory;
  private final AccountConnectorClient accountConnectorClient;
  private final PublisherClient publisherClient;

  @Scheduled(cron = "${task.health-check.cron}")
  public void verifyServicesAreRunning() {
    DomainServiceStatus domainServiceStatus = DomainServiceStatus.INSTANCE;

    try {
      LOGGER.info("Verifying health status of - starting");

      domainServiceStatus.setAccountConnectorUp(isAccountConnectorRunning());
      domainServiceStatus.setPublisherUp(isPublisherRunning());

      LOGGER.info("Verifying health status - done - services are running");
    } catch (RetryableException ex) {
      domainServiceStatus.setAccountConnectorUp(false);
      domainServiceStatus.setPublisherUp(false);
    }
  }

  private boolean isAccountConnectorRunning() {
    ResponseEntity<HealthStatus> response = accountConnectorClient.HeathCheck();

    return (response.getBody().getStatus().equals(SERVICE_UP));
  }

  private boolean isPublisherRunning() {
    ResponseEntity<HealthStatus> response = publisherClient.HeathCheck();

    return (response.getBody().getStatus().equals(SERVICE_UP));
  }

}

这是我的测试方法

@Test
void verifyServicesAreRunning_error() throws FeignException {
  when(accountConnectorClient.HeathCheck()).thenThrow(new RetryableException(500, "message", Request.HttpMethod.GET, new Date(), DataFixture.getRequest()));

  tasksDeclaration.verifyServicesAreRunning();

  verify(accountConnectorClient).HeathCheck();

  assertFalse(DomainServiceStatus.INSTANCE.isAccountConnectorUp());
  assertFalse(DomainServiceStatus.INSTANCE.isPublisherUp());
}

pit测试覆盖率报告告诉我catch语句中的两行代码仍然存在，尽管调用被删除。我遗漏了什么/没有测试什么？
