+    LogOutput is the class for log output. It is required standard for all
+    SDK tests controlled by mint.
+    Here are its attributes:
+            'name': name of the SDK under test, e.g. 's3select'
+            'function': name of the method/api under test with its signature
+                        The following python code can be used to
+                        pull args information of a <method> and to
+                        put together with the method name:
+                        <method>.__name__+'('+', '.join(args_list)+')'
+                        e.g. 'remove_object(bucket_name, object_name)'
+            'args': method/api arguments with their values, in
+                    dictionary form: {'arg1': val1, 'arg2': val2, ...}
+            'duration': duration of the whole test in milliseconds,
+                        defaults to 0
+            'alert': any extra information user is needed to be alerted about,
+                     like whether this is a Blocker/Gateway/Server related
+                     issue, etc., defaults to None
+            'message': descriptive error message, defaults to None
+            'error': stack-trace/exception message(only in case of failure),
+                     actual low level exception/error thrown by the program,
+                     defaults to None
+            'status': exit status, possible values are 'PASS', 'FAIL', 'NA',
+                      defaults to 'PASS'
