This document discusses appium architecture and how it was used to test 20-30 apps developed by 60+ developers over 10 months. It provides information on appium, selendroid, and the different architectures and workflows used for testing Android and iOS apps. Key points covered include the appium server architecture, WebDriver protocol, supported platforms, and challenges faced with testing such as slow test speeds, device failures, and network infrastructure issues.

Appium is an HTTP server that creates
and handles webdriver sessions.
Appium Server is written in node.js

webdriver
webdriver
a platform and language-neutral
interface and associated wire protocol
that allows programs or scripts to
introspect into, and control the
behaviour of, a web browser.

the appium people extended the json
wire protocol for the mobile world (Eg.
WEBVIEW, Connection Type)

on android, appium proxies commands
to a UIAutomator test case running on
the device. For older versions it uses
selendroid.

selendroid
selendroid Architecture
Selendroid is a test automation
framework which drives off the UI of
Android native and hybrid applications
and the mobile web. Tests are written
using the Selenium 2 client API

18. Seite 18
selendroid
selendroid Architecture
Selendroid is based on the Android
instrumentation framework.
Android instrumentation is a set of control
methods or "hooks" in the Android system.
These hooks control an Android component
independently of its normal lifecycle. They
also control how Android loads applications.

Appium Tests
The pain
 Only one appium server instance per
team
 All devices connected over one usb
 Session handling
 Network infrastracture
 Backend

34. Seite 34
Appium Tests
The pain
 Tests need to be very robust
 Webview switching
 Had to tweak the apk for appium tests.
Only one process.
 Setup is complicated and time
consuming (also local)

35. Seite 35
Appium Tests
The pain
 Sometimes devices just fail, because of
other reasons than your code
 Hard to reproduce failures (eg. waiting
for element fails), we built in a retry
 Appium tests are slow

36. Seite 36
Appium Tests
Whats next
 Uncoupling host:port
eg. with consul
 Move to appium client driver,
UIAutomator
 One Device per Acceptance Test ;)
