如何编写用于编组和解组的Junit测试用例

Question

我有下面的代码片段，这些代码使用解组来读取从服务响应接收到的数据。我需要使用junit编写测试用例，以测试代码是否能够解析成功XML和错误XML。

代码段：

ExecuteLegacyAPICallResponse.ExecuteLegacyAPICallResult result = port.executeLegacyAPICall(sessionID,
                    "srtUpdateRealignment", parameters);
            List<Object> resultList = result.getContent();

Iterator<Object> itr = resultList.iterator();
            while (itr.hasNext()) {
                Object o = itr.next();
                LOGGER.info("Object---" + o + " Class----" + o.getClass());

                JAXBContext jaxBContext = JAXBContext.newInstance("webservice.client.wddx");
                Unmarshaller unmarshallerObj = jaxBContext.createUnmarshaller();
                WddxPacket wddxPacket = (WddxPacket) unmarshallerObj.unmarshal((Node) o);

                LOGGER.info("wddxPacket----" + wddxPacket);

                Struct structRealign = (Struct) wddxPacket.getData()
                        .getNullOrBooleanOrNumberOrDateTimeOrStringOrArrayOrStructOrRecordsetOrBinary().get(0);

                LOGGER.info("structRealign----" + structRealign);

                for (Var var : structRealign.getVar()) {
                    if ("return_status".equalsIgnoreCase(var.getName())) {
                        Struct dataStruct = (Struct) var
                                .getNullOrBooleanOrNumberOrDateTimeOrStringOrArrayOrStructOrRecordsetOrBinary().get(0);
                        LOGGER.info("dataStruct return_status----" + dataStruct);
                        isSuccess = isValidStatus(dataStruct);

                        if (!isSuccess) {
                            String errDescription = getStatusDescription(dataStruct);
                            throw new ServiceUnavailableException(errDescription);
                        }
                    }

                    if ("return_data".equalsIgnoreCase(var.getName())) {
                        Struct dataStruct = (Struct) var
                                .getNullOrBooleanOrNumberOrDateTimeOrStringOrArrayOrStructOrRecordsetOrBinary().get(0);
                        for (Var dataVar : dataStruct.getVar()) {
                            LOGGER.info("dataStruct return_data----" + dataStruct);
                            if ("recordset_data".equalsIgnoreCase(dataVar.getName())) {
                                Recordset recordSet = (Recordset) dataVar
                                        .getNullOrBooleanOrNumberOrDateTimeOrStringOrArrayOrStructOrRecordsetOrBinary()
                                        .get(0);
                                LOGGER.info("recordSet ----" + recordSet);
                                for (Field field : recordSet.getField()) {
                                    if ("confirmnum".equalsIgnoreCase(field.getName())) {
                                        List<Object> list = field.getNullOrBooleanOrNumberOrDateTimeOrStringOrBinary();
                                        webservice.client.wddx.String value = (webservice.client.wddx.String) list
                                                .get(0);
                                        confirmNum = value.getvalue();
                                    }
                                }
                            }
                        }
                    }
                }
            }

课程信息以org.apache.xerces.dom.ElementNSImpl的形式出现。

如何将示例XML转换为该对象，以便我的代码能够解组和解析结果？

示例XML-
