Example 55 with HttpResponse

use of org.jboss.netty.handler.codec.http.HttpResponse in project graylog2-server by Graylog2.

the class GELFHttpHandlerTest method testWithoutKeepalive.

@Test
public void testWithoutKeepalive() throws Exception {
    when(headers.get(HttpHeaders.Names.CONNECTION)).thenReturn(HttpHeaders.Values.CLOSE);
    HttpTransport.Handler handler = new HttpTransport.Handler(true);
    handler.messageReceived(ctx, evt);

    HttpResponse response = argument.getValue();
