### Question:
AmazonWebServiceClient { @SuppressWarnings("checkstyle:hiddenfield") public final void setServiceNameIntern(final String serviceName) { this.serviceName = serviceName; } protected  AmazonWebServiceClient(
            final ClientConfiguration clientConfiguration); @Deprecated protected  AmazonWebServiceClient(
            final ClientConfiguration clientConfiguration,
            final RequestMetricCollector requestMetricCollector); protected  AmazonWebServiceClient(
            final ClientConfiguration clientConfiguration,

@Test public void setServiceNameIntern() { final AmazonTestClient client = new AmazonTestClient(); assertEquals(client.getServiceName(), client.getServiceNameIntern()); final String serviceNameOverride = "foo"; assertFalse(serviceNameOverride.equals(client.getServiceName())); client.setServiceNameIntern(serviceNameOverride); assertEquals(serviceNameOverride, client.getServiceName()); }
