+CROSS PLATFORM CROSS TECHNOLOGY

1. You write an automation script (programming skills required) in one of many supported languages

2. By running the script you instantiate an AppiumDriver –the client that connects to the AppiumServer

3. The driver asks the server to perform actions on the UI of the application

4. The server translates the commands for the underlying OS automation tools

5. The device on which the app is running is automatically remote controlled

How It Works – In Short

How It Works – In Short

• You shouldn't have to recompile your app or modify it in any way in order to automate it.

ØVendor-provided automation frameworks are used under the hood:

ØUIAutomation for iOS

ØGoogle’s UIAtomator and Instrumentation (bundled with Selendroid) for Android

Appium’s Philosophy

• You shouldn't be locked into a specific language or framework to write and run your tests.

ØVendor-provided frameworks are wrapped into the WebDriver (aka "Selenium WebDriver"), which specifies a client-server protocol (known as the JSON Wire Protocol). A client can be written in any language and be used to send the appropriate HTTP requests to the server.

Appium’s Philosophy

• A mobile automation framework should be open source, in spirit and practice as well as in name!

ØOpen source project, massive community, frequent fixes and many active committers.

Appium’s Philosophy

Typical Appium Test Script

Typical Appium Test Script

• Not using abstraction to our advantage: low level and high level mixed together

• Low readability

• Low maintainability: bad news if you have a new release every two weeks

The PageObject Pattern

The PageObject Pattern

“Page objects are a classic example of encapsulation -they hide the details of the UI structure and widgetryfrom other components (the tests).”

- Martin Fowler
