Examples with SendMessage org.apache.nifi.websocket.SendMessage used on opensource projects

Example 1 with SendMessage

use of org.apache.nifi.websocket.SendMessage in project nifi by apache.

the class TestPutWebSocket method testSendFailure.

@Test
public void testSendFailure() throws Exception {
    final TestRunner runner = TestRunners.newTestRunner(PutWebSocket.class);
    final WebSocketService service = spy(WebSocketService.class);
    final WebSocketSession webSocketSession = getWebSocketSession();
    final String serviceId = "ws-service";
    final String endpointId = "client-1";
    final String textMessageFromServer = "message from server.";
    when(service.getIdentifier()).thenReturn(serviceId);
    doAnswer(invocation -> {
        final SendMessage sendMessage = invocation.getArgumentAt(2, SendMessage.class);
        sendMessage.send(webSocketSession);
        return null;
    }).when(service).sendMessage(anyString(), anyString(), any(SendMessage.class));
    doThrow(new IOException("Sending message failed.")).when(webSocketSession).sendString(anyString());
    runner.addControllerService(serviceId, service);
    runner.enableControllerService(service);
    final Map<String, String> attributes = new HashMap<>();
    attributes.put(ATTR_WS_CS_ID, serviceId);
    attributes.put(ATTR_WS_ENDPOINT_ID, endpointId);
    attributes.put(ATTR_WS_SESSION_ID, webSocketSession.getSessionId());
    runner.enqueue(textMessageFromServer, attributes);
    runner.run();
    final List<MockFlowFile> succeededFlowFiles = runner.getFlowFilesForRelationship(PutWebSocket.REL_SUCCESS);
    assertEquals(0, succeededFlowFiles.size());
    final List<MockFlowFile> failedFlowFiles = runner.getFlowFilesForRelationship(PutWebSocket.REL_FAILURE);
    assertEquals(1, failedFlowFiles.size());
    final MockFlowFile failedFlowFile = failedFlowFiles.iterator().next();
    assertNotNull(failedFlowFile.getAttribute(ATTR_WS_FAILURE_DETAIL));
    final List<ProvenanceEventRecord> provenanceEvents = runner.getProvenanceEvents();
    assertEquals(0, provenanceEvents.size());
}

Example 2 with SendMessage

use of org.apache.nifi.websocket.SendMessage in project nifi by apache.

the class TestPutWebSocket method testSuccess.

@Test

    runner.enableControllerService(service);
    runner.setProperty(PutWebSocket.PROP_WS_MESSAGE_TYPE, "${" + ATTR_WS_MESSAGE_TYPE + "}");
    // Enqueue 1st file as Text.
    final Map<String, String> attributes = new HashMap<>();
    attributes.put(ATTR_WS_CS_ID, serviceId);
    attributes.put(ATTR_WS_ENDPOINT_ID, endpointId);
    attributes.put(ATTR_WS_SESSION_ID, webSocketSession.getSessionId());
    attributes.put(ATTR_WS_MESSAGE_TYPE, WebSocketMessage.Type.TEXT.name());
    runner.enqueue(textMessageFromServer, attributes);
    // Enqueue 2nd file as Binary.
    attributes.put(ATTR_WS_MESSAGE_TYPE, WebSocketMessage.Type.BINARY.name());
