### Question:
SDNCRestClient { @Async public void executeRequest(SDNCAdapterRequest bpelRequest) { logger.debug("BPEL Request: {}", bpelRequest); try { Thread.sleep(5000); } catch (InterruptedException e) { logger.error(LoggingAnchor.FOUR, MessageEnum.BPMN_GENERAL_EXCEPTION.toString(), "SDNC", ErrorCode.UnknownError.getValue(), "Exception processing request to SDNC", e); Thread.currentThread().interrupt(); } String bpelReqId = bpelRequest.getRequestHeader().getRequestId(); String callbackUrl = bpelRequest.getRequestHeader().getCallbackUrl(); String msoAction = bpelRequest.getRequestHeader().getMsoAction(); String sdncReqBody = null; RequestTunables rt = new RequestTunables(bpelReqId, msoAction, bpelRequest.getRequestHeader().getSvcOperation(), bpelRequest.getRequestHeader().getSvcAction()); rt = tunablesMapper.setTunables(rt); rt.setSdncaNotificationUrl(env.getProperty(Constants.MY_URL_PROP)); if ("POST".equals(rt.getReqMethod())) { Node node = (Node) bpelRequest.getRequestData(); Document reqDoc = node.getOwnerDocument(); if (Constants.MSO_ACTION_LCM.equals(msoAction)) { sdncReqBody = Utils.genSdncLcmReq(reqDoc, rt); } else if (Constants.MSO_ACTION_MDONS.equals(msoAction)) { sdncReqBody = Utils.genOpticalSdncReq(reqDoc, rt); } else { sdncReqBody = Utils.genSdncReq(reqDoc, rt); } } else if ("PUT".equals(rt.getReqMethod())) { Node node = (Node) bpelRequest.getRequestData(); Document reqDoc = node.getOwnerDocument(); sdncReqBody = Utils.genSdncPutReq(reqDoc, rt); } SDNCResponse sdncResp = getSdncResp(sdncReqBody, rt); logger.debug("Got the SDNC Response: {}", sdncResp.getSdncRespXml()); sendRespToBpel(callbackUrl, sdncResp); }  @Async void executeRequest(SDNCAdapterRequest bpelRequest); SDNCResponse getSdncResp(String sdncReqBody, RequestTunables rt); void sendRespToBpel(String bpelUrl, SDNCResponse sdncResp);  }### Answer:
@Test public void executeRequestInterrupted() { Thread.currentThread().interrupt(); sdncClient.executeRequest(null); assertTrue(Thread.interrupted()); }
