There are many capabilities that Appium supports accordingly, we can categorize the Capabilities into three parts:Īppium (default), or UiAutomator2, Espresso, or UiAutomator1 for Android, or XCUITest or Instruments for iOS, It follows the Client-Server Architecture. Desired Capabilities are key/value pairs encoded in JSON format and are sent to the Appium Server by the Appium client when a new automation session is requested. The requests are then handled in different ways, depending on the platform on which it is running on.įor example, we can request the environment (emulator or real-device), which version of the operating system to run the test on, and more. Appium server also receives HTTP requests from the client libraries in JSON format. It also gives the standards by which we want to run our automation script. Initially, Desired Capabilities helped us to configure the Appium server.

This also allows the web driver to build a connection with a server and a client to perform automation. It is developed by web driver developers but According to them, the protocol is a bunch of standardized endpoints that are exposed to the client using a RESTful API. Basically, JSON Wire Protocol is the mechanism used for communicating between client and server. Desired Capabilitiesĭesired Capabilities, also known as JSON Wire Protocol, refer to the mixture of key-value pairs encoded in a JSON object.

Appium server is scripted in Node.js and fits with leading client libraries like Java, Python, Ruby, PHP, and others.Īppium does not depend on mobile device operating systems because it has a frame that turns the Selenium web driver commands to UIAutomator commands for Android and iOS only depends on the device type rather than its OS. After that, It is only bound to the mobile application testing field. It also required a connection between mobile and Appium server that things which help to make a proper bond in between are “ Desire Capabilities.”Īppium tool is an open-source, cross-platform automation testing tool, and therefore the tool focuses on both Android and iOS apps.
Initially, In this blog, we learn about “ why we need Desired Capabilities in Appium“, so as we discussed earlier, Appium is a tool used for mobile testing.
