@Test
    public void testSendWebhook() throws KafkaConsumerException {
        PodamFactory factory = new PodamFactoryImpl();
        WebhookEventDTO<MeetingEventPayload> webhookEventDTO = factory.manufacturePojo(WebhookEventDTO.class, MeetingEventPayload.class);
        Mockito.when(u2CBizService.getWebhookFeatureToggleEndpoint(any(), any(), eq("webhook-engine"), any())).thenReturn("https://www.ciscospark.com/v1");
        Mockito.doNothing().when(webhookFeignClient).sendWebhookEvent(any(), any(), any());
        webhookRemoteService.sendWebhook(webhookEventDTO, "trackingId");
        Mockito.verify(webhookFeignClient, Mockito.times(1)).sendWebhookEvent(any(), any(), any());
    } 

When I run this method directly in IntelliJ IDEA, it works fine. However, when I run it through Maven test, it fails, showing the following error：

[ERROR]   WebinarFeignServiceTest.testHeaderInterceptor:44 » UnfinishedStubbing 
Unfinished stubbing detected here:
-> at com.cisco.webex.notificationservice.remote.webhook.WebhookRemoteServiceTest.testSendWebhook(WebhookRemoteServiceTest.java:45)

E.g. thenReturn() may be missing.
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod();
Hints:
 1. missing thenReturn()
 2. you are trying to stub a final method, which is not supported
 3. you are stubbing the behaviour of another mock inside before 'thenReturn' instruction is completed

I don’t have any idea to this failure.
