How Does JSON Wire Protocol Work With Appium?

Here, we shall discuss how Appium works and the concepts of Appium servers. This blog gives a complete knowledge of Appium architecture.

What is Appium?

Appium is an open-source automation framework. Appium allows developers and testers to avoid the time-consuming process of manually creating testing tools for each device. An Appium server can be built to relay instructions directly from a generalized testing script to the device.

What is JSON Wire Protocol?

JSON Wire Protocol is a widely used standard for facilitating communication between client libraries and servers in a dynamic network. It is a platform-independent tool that uses the JSON Wire Protocol feature.

JSON is an abbreviation of JavaScript Object Notation, which represents complex data structures. The wire protocol is a method of sending data from one location to another.

How Does JSON Wire Protocol Work With Appium?

Appium architecture facilitates communication between the Appium Server and client libraries using the JSON Wire protocol over an HTTP REST request with JSON inputs. This arrangement employs serialization and deserialization techniques to generate object data in JSON format.

The server is open-source. It does not require a server to understand the programming languages of the client libraries; instead, it only needs to identify the protocol in order to create and manage automation sessions. It is a very simple and easy process.

JSON Protocol Architecture:

Local End: It is a client-side protocol, and the client libraries are written in a specified programming language.
Remote End: It is a server-side protocol.
Intermediary End: Proxy systems can function as the remote and local ends.
Endpoint Node: It is the node structure’s final remote end.

The server reads requests from local end clients and writes responses through a TCP socket called the remote end. For example, the new session command can be used to create a new WebDriver session to perform test operations on the endpoint node, or the find element command can be used to retrieve specific elements.

Installing Appium:

There are two versions of Appium:

CLI-based Appium Server
GUI-based Appium Desktop

CLI-based Appium Server Installation:

Appium provides a vibrant GUI desktop app for managing test automation operations. Moreover, when integrating testing into your CI pipelines, you must use the scripts to start the Appium Server.

GUI-based Appium Desktop:

It extends the Appium Server with a graphical user interface and includes Appium Inspector.
