JSON is a lightweight data-interchange format that is easy for humans to read and write and for machines to parse and generate. It is built on two structures: a collection of name/value pairs and an ordered list of values. JSON is text-based and language independent, yet closely resembles JavaScript object syntax. It is used primarily to transmit data between a server and web application, serving as an alternative to XML. Compared to XML, JSON is simpler, faster and easier to use.

An Introduction to JSON JavaScript Object NotationAhmed Muzammil
JSON (JavaScript Object Notation), is a text-based open standard designed for human-readable data interchange. It is derived from the JavaScript scripting language for representing simple data structures and associative arrays, called objects.
Despite its relationship to JavaScript, it is language-independent, with parsers available for many languages.
The JSON format was originally specified by Douglas Crockford, and is described in RFC 4627. The official Internet media type for JSON is application/json. The JSON filename extension is .json.
The JSON format is often used for serializing and transmitting structured data over a network connection. It is used primarily to transmit data between a server and web application, serving as an alternative to XML.

Presentation on various definitions for JSON including JSON-RPC, JSPON, JSON Schema, JSONP and tools for working these definitions including Persevere client and server..
JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa). You'll come across it quite often, so in this article, we give you all you need to work with JSON using JavaScript, including parsing JSON so you can access data within it, and create JSON.
JSON means JavaScript Object Notation. JSON is used as an interface to connect server/backend to be able to send data to frontend in web technology or vice-versa. Not just only in web, Server/API/Backend also can use JSON to response data to Mobile. In this slide I explain what JSON is and show its data type and usage. Hope you like it.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Language independent.
Text based.
Easy to parse .
2
3. Why JSON?
JSON is recognized natively by JavaScript. No need for parsing an
XML document to extract the data.
3
4. JSON is Not…
JSON is not a document format.
JSON is not a markup language.
4
5. Properties of JSON
Human and machine readable format.
No support for Unicode.
Self-documenting format that describes structure and field names.
Strict syntax and parsing requirements.
Represents the most general computer science data structures like
records, lists and trees.
5
6. Where can JSON be used?
Can be used for transferring medium amounts of data.
Used in Java Script and then rendered on HTML pages.
AJAX has many applications for JSON.
Use JSON for applications that are browser based.
6
7. JSON Data Types
Strings -Control Characters
Number-Integer, Real and Floating
Boolean-True and False
Null
7
8. JSON Data Types (Cont…)
String
Strings must be delimited by the double quote characters.
Example: ”Address”, "444 Colombia"
Boolean
In JSON “True" and “False" are pre-defined keywords.
Example: “Active":True
8
9. Data types (Cont…)
Number
JSON includes positive integers and Negative integers.
Example: “Total points” -123
Null
Null string, also known as an empty string, is a string of zero length.
Example: “Email":null
9
11. JSON Object
JSON Object Notation
JSON object is an unordered set of name/value pairs and ordered
list of values.
Object begins with { (left brace) and ends with } (right brace).
Each name is followed by (colon).
Name/value pairs are separated by , (comma).
11
12. JSON Representation of an Object
Var HomeAddress =
{
"Address" : “Srini",
"City" : “Bangalore",
"PostalCode" : 580006
};
12
13. JSON Functions
JSON_decode — Decodes a JSON string.
JSON_encode — Returns the JSON representation of a value.
JSON_last_error — Returns the last error occurred.
13
14. JSON Decode
Decode parses the strings as a JSON-syntax string and returns the
generic JSON object representation.
json_decode()
mixed json_decode ( string $json , bool $assoc)
Takes a JSON encoded string and converts it into a PHP value.
$json
The JSON string being decoded
$assoc
False ----Return the value as an object
True ----Return the value as an associative array
14
16. JSON Encode
JSON encode returns the JSON representation of a value.
string json_encode ( mixed $value )
Returns a string containing the JSON representation of $value.
$value
Value being encoded, Can be any type except a resource.
Function only works with UTF-8 encoded data.
16
18. JSON in JavaScript
JavaScript Object Notation is a lightweight data-interchange
format that is completely language independent text format
which is fast and easy to understand.
18
19. Example - JSON in JavaScript
<html>
<head>
<title>
Object creation in JSON in JavaScript
</title>
<script language="javascript" >
var JSONObject =
{
"name" : "Amit“,
“address" : "Bangalore“,
"age" : 23,
"phone" : "4565763",
“MobileNo" : 981100092
};
19
20. Example - JSON in JavaScript (Cont…)
document.write("<h2><font color='skyblue'>Name</font>::“
+JSONObject.name+"</h2>");
document.write("<h2><font color='skyblue'>Address</font>::“
+JSONObject.address+"</h2>");
document.write("<h2><font color='skyblue'>Age</font>::“
+JSONObject.age+"</h2>");
document.write("<h2><font color='skyblue'>Phone No.</font>::“
+JSONObject.phone+"</h2>");
document.write("<h2><font color='skyblue'>Mobile No.</font>::“
+JSONObject.MobileNo+"</h2>");
</script>
</head>

21. AJAX with JSON
Both XML and JSON use structured approaches to mark up data.
More and more web services are supporting JSON.
Example
Yahoo's various search services, travel planners, and highway
traffic services.
21
22. Why JSON is Better than Ajax?
JSON is widely used in AJAX. The X in AJAX stands for XML.
Example
{
"fullname": "Swati Kumar“, "org": "Columbia",
}
<?xml version='1.0‘ encoding='UTF-8'?>
<element>
<fullname>Swati Kumar</fullname>
<org>Columbia</org>
</element>
22
23. JSON and XML
Benefits of JSON
The easiness of reading
The easiness of using
Benefits of XML
XML is extensible.
Widely used and recognized by almost all programming languages.
Unfortunally, both XML and JSON are enable to integrate a large
amount of data in binary form.
23
25. Equivalent for the above in XML could be
<Person>
<firstName>John</firstName>
<lastName>Smith</lastName>
<age>25</age>
<address>
<streetAddress>21 2nd Street</streetAddress>
<city>New York</city>
<state>NY</state>
<postalCode>10021</postalCode>
</address>
<phoneNumber type="home">212 555-1234</phoneNumber>
<phoneNumber type="fax">646 555-4567</phoneNumber>
<newSubscription>false</newSubscription>
<companyName />
</Person>
25
26. JSON is Like XML because…
Both are self-describing and thus human readable.
Both are hierarchical (i.e. we can have values within values.)
Both can be parsed and used by lots of programming languages.
Both can be passed around using AJAX (i.e. httpWebRequest).
26
27. JSON Vs XML
JSON stands for JavaScript Object Notation, Considered as the
subset of JavaScript.
XML on the other hand is a mark-up language that could be used in
different languages.
Parsing JSON encoded data is much faster than parsing XML
encoded data.
27
29. Why Use JSON Over XML?
Lighter and faster than XML as on-the-wire data.
JSON objects are typed while XML data is type less.
JSON types are string, number, array, Boolean.
XML data are all string.
Data is readily accessible as JSON objects in your JavaScript Code.
XML data needed to be parsed and assigned to variables through
tedious DOM APIs.
29
30. Features of JSON
Provides multiple functionalities such as encode, decode/parse.
Flexible, simple and easy to use.
Supports streaming output of JSON text.
Heap based parser.
High performance.
No dependency on external libraries.
30
31. JSON Data Interchange
JSON is a simple, common representation of data.
Communication between servers and browser clients.
Communication between peers.
Language independent data interchange.
31
