Examples with PullResponse com.google.api.services.pubsub.model.PullResponse used on opensource projects

Example 1 with PullResponse

use of com.google.api.services.pubsub.model.PullResponse in project beam by apache.

the class PubsubJsonClientTest method pullOneMessage.

@Test
public void pullOneMessage() throws IOException {
    String expectedSubscription = SUBSCRIPTION.getPath();
    PullRequest expectedRequest = new PullRequest().setReturnImmediately(true).setMaxMessages(10);
    PubsubMessage expectedPubsubMessage = new PubsubMessage().setMessageId(MESSAGE_ID).encodeData(DATA.getBytes()).setPublishTime(String.valueOf(PUB_TIME)).setAttributes(ImmutableMap.of(TIMESTAMP_ATTRIBUTE, String.valueOf(MESSAGE_TIME), ID_ATTRIBUTE, RECORD_ID));
    ReceivedMessage expectedReceivedMessage = new ReceivedMessage().setMessage(expectedPubsubMessage).setAckId(ACK_ID);
    PullResponse expectedResponse = new PullResponse().setReceivedMessages(ImmutableList.of(expectedReceivedMessage));
    Mockito.when((Object) (mockPubsub.projects().subscriptions().pull(expectedSubscription, expectedRequest).execute())).thenReturn(expectedResponse);
    List<IncomingMessage> acutalMessages = client.pull(REQ_TIME, SUBSCRIPTION, 10, true);
    assertEquals(1, acutalMessages.size());
    IncomingMessage actualMessage = acutalMessages.get(0);
    assertEquals(ACK_ID, actualMessage.ackId);
    assertEquals(DATA, new String(actualMessage.elementBytes));
    assertEquals(RECORD_ID, actualMessage.recordId);
    assertEquals(REQ_TIME, actualMessage.requestTimeMsSinceEpoch);
    assertEquals(MESSAGE_TIME, actualMessage.timestampMsSinceEpoch);
}

Example 2 with PullResponse

use of com.google.api.services.pubsub.model.PullResponse in project beam by apache.
