### Question:
JsonUtils { public static boolean getJsonBooleanValue(String jsonStr, String keys) { try { Object rawValue = getJsonRawValue(jsonStr, keys); if (rawValue == null) { return false; } else { if (rawValue instanceof Boolean) { logger.debug("getJsonBooleanValue(): the raw value is a Boolean Object={}", rawValue); return (Boolean) rawValue; } else { logger.debug("getJsonBooleanValue(): the raw value is NOT an Boolean Object={}", rawValue); return false; } } } catch (Exception e) { logger.debug( "getJsonBooleanValue(): unable to parse json to retrieve value for field={}. Exception was: {}", keys, e.toString(), e); } return false; }  static String xml2json(String xml, Boolean pretty); static String xml2json(String xml); static String json2xml(String jsonStr, Boolean pretty); static String toXMLString(Object obj, String tagName); static String json2xml(String jsonStr); static String prettyJson(String jsonStr); static Iterator<String> getJsonIterator(String jsonStr); static String getJsonRootProperty(String jsonStr); static String getJsonValue(String jsonStr, String keys); static String getJsonNodeValue(String jsonStr, String keys); static int getJsonIntValue(String jsonStr, String keys); static boolean getJsonBooleanValue(String jsonStr, String keys); static String getJsonParamValue(String jsonStr, String keys, String name); static String getJsonParamValue(String jsonStr, String keys, String name, int index); static String getJsonValueForKey(String jsonStr, String key); static String getJsonValueForKey(JSONObject jsonObj, String key); static Integer getJsonIntValueForKey(JSONObject jsonObj, String key); static Boolean getJsonBooleanValueForKey(JSONObject jsonObj, String key); static Boolean jsonValueExists(String jsonStr, String keys); static String addJsonValue(String jsonStr, String keys, String value); static String updJsonValue(String jsonStr, String keys, String newValue); static String delJsonValue(String jsonStr, String keys); Map<String, String> jsonStringToMap(DelegateExecution execution, String entry); Map<String, String> entryArrayToMap(DelegateExecution execution, String entryArray, String keyNode,
            String valueNode); Map<String, String> entryArrayToMap(String entryArray, String keyNode, String valueNode); List<String> StringArrayToList(Execution execution, String jsonArray); List<String> StringArrayToList(String jsonArray); List<String> StringArrayToList(JSONArray jsonArray); static boolean jsonElementExist(String jsonStr, String keys); static String jsonSchemaValidation(String jsonStr, String jsonSchemaPath);  }### Answer:
@Test public void getJsonBooleanValueTest() throws IOException { String response = this.getJson("SDNCServiceResponseExample.json"); boolean isBoolean = JsonUtils.getJsonBooleanValue(response, "SDNCServiceResponse.responseCode"); assertEquals(false, isBoolean); }
@Test public void getJsonBooleanValueErrorTest() throws IOException { String response = this.getJson("SDNCServiceResponseExample.json"); assertEquals(false, JsonUtils.getJsonBooleanValue(response, null)); }
