class Service{
    // The required parameter is a way to authenticate with Event Hubs using credentials.
// The connectionString provides a way to authenticate with Event Hub.
@Setter
EventHubProducerClient producer = new EventHubClientBuilder()
    .connectionString(
        "Endpoint={fully-qualified-namespace};SharedAccessKeyName={policy-name};SharedAccessKey={key}",
        "event-hub-name")
    .buildProducerClient();
List<EventData> events = Arrays.asList(new EventData("test-event-1"), new EventData("test-event-2"));

// Creating a batch without options set, will allow for automatic routing of events to any partition.
EventDataBatch batch = producer.createBatch();
for (EventData event : events) {
    if (batch.tryAdd(event)) {
        continue;
    }

    producer.send(batch);
    batch = producer.createBatch();
    if (!batch.tryAdd(event)) {
        throw new IllegalArgumentException("Event is too large for an empty batch.");
    }
}
}

class ServiceMock{
@Mock 
Service service;
@Mock 
EventHubProducerClient eventHubProducerClient;
@Mock
EventDataBatch eventDataBatch;

EventData eventData;

//Dummy Method to Mock the connection details and set the producer client
@BeforeEach
void preLoad()
{
    service.setEventHubProducerClient(eventHubProducerClient);
}

@Test
void dummy_Tests()
{
    when(eventDataBatch.tryAdd(any(EventData.class))).thenReturn(true);
    Mockito.doReturn(eventDataBatch).when(eventHubProducerClient).createBatch();
    doNothing().when(eventHubProducerClient).send(any(EventDataBatch.class))
}}
