Example 1 with InputStreamInternalImpl

use of org.apache.samza.operators.stream.InputStreamInternalImpl in project samza by apache.

the class TestStreamGraphImpl method testGetInputStream.

@Test

    when(mockRunner.getStreamSpec("test-stream-1")).thenReturn(testStreamSpec);
    StreamGraphImpl graph = new StreamGraphImpl(mockRunner, mockConfig);
    BiFunction<String, MessageType, TestInputMessageEnvelope> xMsgBuilder = (k, v) -> new TestInputMessageEnvelope(k, v.getValue(), v.getEventTime(), "input-id-1");
    MessageStream<TestMessageEnvelope> mInputStream = graph.getInputStream("test-stream-1", xMsgBuilder);
    assertEquals(graph.getInputStreams().get(testStreamSpec), mInputStream);
    assertTrue(mInputStream instanceof InputStreamInternalImpl);
    assertEquals(((InputStreamInternalImpl) mInputStream).getMsgBuilder(), xMsgBuilder);
    String key = "test-input-key";
    MessageType msgBody = new MessageType("test-msg-value", 333333L);
    TestMessageEnvelope xInputMsg = ((InputStreamInternalImpl<String, MessageType, TestMessageEnvelope>) mInputStream).getMsgBuilder().apply(key, msgBody);
    assertEquals(xInputMsg.getKey(), key);
    assertEquals(xInputMsg.getMessage().getValue(), msgBody.getValue());
