Examples with CallOptions io.grpc.CallOptions used on opensource projects

Example 81 with CallOptions

use of io.grpc.CallOptions in project grpc-java by grpc.

the class LoggingChannelProviderTest method newChannelBuilder_interceptorCalled.

@Test
public void newChannelBuilder_interceptorCalled() {
    ClientInterceptor interceptor = mock(ClientInterceptor.class, delegatesTo(new NoopInterceptor()));
    InternalLoggingChannelInterceptor.Factory factory = mock(InternalLoggingChannelInterceptor.Factory.class);
    when(factory.create()).thenReturn(interceptor);
    LoggingChannelProvider.init(factory);
    ManagedChannelBuilder<?> builder = Grpc.newChannelBuilder("localhost", TlsChannelCredentials.create());
    ManagedChannel channel = builder.build();
    CallOptions callOptions = CallOptions.DEFAULT;
    ClientCall<Void, Void> unused = channel.newCall(method, callOptions);
    verify(interceptor).interceptCall(same(method), same(callOptions), ArgumentMatchers.<Channel>any());
    channel.shutdownNow();
    LoggingChannelProvider.finish();
}
