Appium is an open source test automation framework for use with native, 

hybrid and mobile web apps. 
It drives iOS and Android apps using the WebDriver protocol.

Philosophy

• You shouldn't have to recompile your app or modify it in any way in order to automate it.
• You shouldn't be locked into a specific language or framework to write and run your tests.
• A mobile automation framework shouldn't reinvent the wheel when it comes to automation APIs.
• A mobile automation framework should be open source, in spirit and practice as well as in name!

Concepts

Client/Server Architecture

Appium is at its heart a webserver that exposes a REST API. It receives connections from a client, listens for commands, executes those commands on a mobile device, and responds with an HTTP response representing the result of the command execution. The fact that we have a client/server architecture opens up a lot of possibilities: we can write our test code in any language that has a http client API, but it is easier to use one of the Appium client libraries. We can put the server on a different machine than our tests are running on. We can write test code and rely on a cloud service like Sauce Labs to receive and interpret the commands.

Automation is always performed in the context of a session. Clients initiate a session with a server in ways specific to each library, but they all end up sending a POST /session request to the server, with a JSON object called the 'desired capabilities' object. At this point the server will start up the automation session and respond with a session ID which is used for sending further commands.

Session

Desired capabilities are a set of keys and values (i.e., a map or hash) sent to the Appium server to tell the server what kind of automation session we're interested in starting up. There are also various capabilities which can modify the behavior of the server during automation. For example, we might set the platformName capability to iOS to tell Appium that we want an iOS session, rather than an Android one. Or we might set the safariAllowPopups capability to true in order to ensure that, during a Safari automation session, we're allowed to use JavaScript to open up new windows. See the capabilities doc for the complete list of capabilities available for Appium.

Desired Capabilities

Appium is a server written in Node.js.

It can be built and installed from source or installed directly from NPM.

Appium Server

There are client libraries (in Java, Ruby, Python, PHP, JavaScript, and C#) which support Appium's extensions to the WebDriver protocol. When using Appium, you want to use these client libraries instead of your regular WebDriver client. You can view the full list of libraries here.

Appium Clients

There exist GUI wrappers around the Appium server that can be downloaded. These come bundled with everything required to run the Appium server, so you don't need to worry about Node. They also come with an Inspector, which enables you to check out the hierarchy of your app. This can come in handy when writing tests.
