Example 21 with AddressResolver

use of io.grpc.internal.DnsNameResolver.AddressResolver in project grpc-java by grpc.

the class GrpclbNameResolverTest method resolve_nullResourceResolver.

@Test
public void resolve_nullResourceResolver() throws Exception {
    InetAddress backendAddr = InetAddress.getByAddress(new byte[] { 127, 0, 0, 0 });
    AddressResolver mockAddressResolver = mock(AddressResolver.class);
    when(mockAddressResolver.resolveAddress(anyString())).thenReturn(Collections.singletonList(backendAddr));
    ResourceResolver resourceResolver = null;
    resolver.setAddressResolver(mockAddressResolver);
    resolver.setResourceResolver(resourceResolver);
    resolver.start(mockListener);
    assertThat(fakeClock.runDueTasks()).isEqualTo(1);
    verify(mockListener).onResult(resultCaptor.capture());
    ResolutionResult result = resultCaptor.getValue();
    assertThat(result.getAddresses()).containsExactly(new EquivalentAddressGroup(new InetSocketAddress(backendAddr, DEFAULT_PORT)));
    assertThat(result.getAttributes()).isEqualTo(Attributes.EMPTY);
    assertThat(result.getServiceConfig()).isNull();
}
