### Question:
ConfigSerializer implements ComprehendSerializer<PreprocessingConfigRequest> { public static PreprocessingConfigRequest transformConfigMapToConfigRequest( @NonNull Map<String, ComprehendConfiguration> configMap) { List<ComprehendConfiguration> configList = new ArrayList<>(configMap.values()); return new PreprocessingConfigRequest(configList); }  PreprocessingConfigRequest deserialize(@NonNull final String input); String serialize(@NonNull PreprocessingConfigRequest configRequest); static Map<String, ComprehendConfiguration> transformConfigRequestToConfigMap(
            @NonNull PreprocessingConfigRequest configRequest); static PreprocessingConfigRequest transformConfigMapToConfigRequest(
            @NonNull Map<String, ComprehendConfiguration> configMap);  }### Answer:
@Test public void SucceedTransformConfigMapToConfigRequest() { configRequest = ConfigSerializer.transformConfigMapToConfigRequest(TestConstants.getConfigMap()); configList = configRequest.getComprehendConfigurations(); assertEquals(1, configList.size()); ComprehendConfiguration object = configList.get(0); Assert.assertEquals(TestConstants.FIELD_NAME, object.getFieldName()); Assert.assertEquals(TestConstants.COMPREHEND_OPERATIONS, object.getComprehendOperations()); Assert.assertEquals(TestConstants.LANGUAGE_CODE, object.getLanguageCode()); }
