我正在为一个负载平衡器编写单元测试，目标是能够过滤掉基于URI的某些服务。然而，测试总是失败，因为它根本没有得到正确的URI！下面是测试类：

public class FilteringDiscoveryClientTest {
   private static DiscoveryClient mockClient;

   @BeforeAll
   public static void setUp(){
      SimpleDiscoveryProperties properties = new SimpleDiscoveryProperties();
      Map<String, List<DefaultServiceInstance>> instances = new HashMap<>();

      DefaultServiceInstance testInstance1_1 = new DefaultServiceInstance();
      testInstance1_1.setUri(URI.create("http://my.service.id.1/1"));
      testInstance1_1.setServiceId("my.service.id.1");
      DefaultServiceInstance testInstance1_2 = new DefaultServiceInstance();
      testInstance1_2.setUri(URI.create("http://my.service.id.1/2"));
      testInstance1_2.setServiceId("my.service.id.1");
      DefaultServiceInstance testInstance2_1 = new DefaultServiceInstance();
      testInstance2_1.setUri(URI.create("http://my.service.id.2/1"));
      testInstance2_1.setServiceId("my.service.id.2");
      DefaultServiceInstance testInstance2_2 = new DefaultServiceInstance();
      testInstance2_2.setUri(URI.create("http://my.service.id.2/2"));
      testInstance2_2.setServiceId("my.service.id.2");
      instances.put(
         "my.service.id.1",
         Arrays.asList(testInstance1_1, testInstance1_2)
      );
      instances.put(
         "my.service.id.2",
         Arrays.asList(testInstance2_1, testInstance2_2)
      );

      properties.setInstances(instances);
      SimpleDiscoveryClient client = new SimpleDiscoveryClient(properties);

      mockClient = client;
   }

@Test
   public void testGetServicesFilteringOutSingleService() {
      FilteringDiscoveryClient client = new FilteringDiscoveryClient(
         mockClient,
         i -> !i.getUri().getAuthority().equals("my.service.id.1")
      );

      assertFalse(client.getServices().contains("my.service.id.1"), "list of services not expected to contain service 1");
      assertTrue(client.getServices().contains("my.service.id.2"), "list of services expected to contain service 2");
   }
}

assertFalse失败，因为i.getUri().getAuthority()返回null：80，而不是实际传递的URI。在setup()期间，根据调试器，这一切似乎都设置正确。您知道我的测试哪里出错了吗？我应该在开始时设置不同的URI吗？
编辑：也许我应该添加FilteringDiscoveryClient的外观

public class FilteringDiscoveryClient implements DiscoveryClient {
   private final DiscoveryClient delegate;
   private final Predicate<ServiceInstance> filter;

   public FilteringDiscoveryClient(DiscoveryClient delegate, Predicate<ServiceInstance> filter) {
      Assert.notNull(delegate, "delegate must not be null");
      Assert.notNull(delegate, "filter must not be null");

      this.delegate = delegate;
      this.filter = filter;
   }

   @Override
   public String description() {
      return delegate.description();
   }

   @Override
   public List<ServiceInstance> getInstances(String serviceId) {
      return delegate.getInstances(serviceId).parallelStream().filter(filter).collect(Collectors.toList());
   }

   @Override
   public List<String> getServices() {
      return delegate.getServices().parallelStream().filter(s -> !getInstances(s).isEmpty()).collect(Collectors.toList());
   }
}
