Appium is an “HTTP Server” written using Node.js platform and drives iOS and Android session using Webdriver JSON wire protocol. Hence, before initializing the Appium Server, Node.js must be pre-installed on the system

When Appium is downloaded and installed, then a server is setup on our machine that exposes a REST API

It receives connection and command request from the client and execute that command on mobile devices (Android / iOS)

It responds back with HTTP responses. Again, to execute this request, it uses the mobile test automation frameworks to drive the user interface of the apps. Framework like

Apple Instruments for iOS (Instruments are available only in Xcode 3.0 or later with OS X v10.5 and later)

Google UIAutomator for Android API level 16 or higher

Selendroid for Android API level 15 or less

Ans:

Pros:

–

For programmer irrespective of the platform, he is automating ( Android or iOS) all the complexities will remain under single Appium server

It opens the door to cross-platform mobile testing which means the same test would work on multiple platforms

Appium does not require extra components in your App to make it automation friendly

It can automate Hybrid, Web and Native mobile applications

Cons:

–

Running scripts on multiple iOS simulators at the same time is possible with Appium

It uses UIAutomator for Android Automation which supports only Android SDK platform, API 16 or higher and to support the older API’s they have used another open source library called Selendroid

Q.9 Explain what is APPIUM INSPECTOR?

Ans:

Similar to Selenium IDE record and Playback tool, Appium has an “Inspector” to record and playback. It records and plays native application behavior by inspecting DOM and generates the test scripts in any desired language. However, Appium Inspector does not support Windows and use UIAutomator viewer in its option.
