Practical Tips and Tricks for Testing of Android Applications © Copyright 2013 Yury Makedonov2
 This workshop is for testers who are switching from
Windows and browser based applications to
smartphone applications
 Novice testers are also welcome.
Target audience

1. Introduction
2. General test approach is the same as in other fields
3. Installation of Android application to be tested
4. Android fragmentation
5. Each application in its own VM
6. Tools
7. Main test ideas
8. Additional sources of test ideas
9. Q & A
Outline

 I have many years of testing experience:
 Functional Testing
 Test Automation
 Performance Testing
 etc.
 In 2013 I started my first smartphone project:
 YouDo Android application
 To-do List for procrastinators
 My role: product owner and tester
Introduction

 You can use all skills and knowledge you have
acquired while testing other applications:
 Test Strategy
 Test Approach
 Test Cases
 Test Reports
 Defects Management
 etc.
General test approach

 You need a SIM card to use a smartphone
 SIM card sizes
 SIM
 Mini SIM
 Micro SIM
 LG SIM
 Nano SIM
 SIM card cutters and adapters
 Data plan for each test phone?
Smartphones and SIM cards

 How to install an Android application:
 Google Play Store - requires registration
 Enable installation from “Unknown sources”:
 Download from a web site
 Receive by e-mail
 From SD card
 From a PC connected with a USB cable
 Web browser
 Chrome
 Dolphin
 Maxthon
 E-mail client
 The same challenge when importing data into app
Installation of Android application to be tested

com.udlst.youdo.main
Domain Subdomain Activity
 Package name (in the application manifest):
 Signed vs. unsigned application
 Test vs. production certificates
 ProGuard
 Different versions of external libraries
 Basic Build Sanity Test – touches all libraries
 Application version number
 Strict mode
 Developer Options
Application build options

 Google Play Store
 Alpha Test
 Beta Test
 Twitter test account
 Facebook test account
Test environments

 A variety of Android devices with:
 Different versions of Android OS
 Different Settings
 Different way to access “Options” menu items
 New OS features should be supported by hardware
 Different screen sizes
 Different manufacturers
 Different default options
 Different default applications
 Failure to install Chrome on LG phone
 Phone vs. tablet layouts
 More extreme differences than in Windows world
Android Fragmentation

 Version of Android OS vs. API Level
 http://androidfragmentation.com
 “Android Analyzer” application
 Google Nexus vs. other phones:
 Nexus – pure Android experience
 Other phones – a lot of “garbageware” applications
and applications with modified/limited functions
Android Fragmentation
Version Code name API level
4.3 Jelly Bean 18
4.2.x Jelly Bean 17
4.1.x Jelly Bean 16
4.0.0–4.0.4 Ice Cream Sandwich 14, 15
3.1 – 3.2 Honeycomb 11, 12, 13
2.3.3 – 2.3.7 Gingerbread 10

 Application is installed and executed in its own VM:
 Cached data
 Application data
 Cleaning data and reinstalling applications
 Isolation between applications
 Isolation between application and OS
 Rooting Android device
Application in a Virtual Machine

 Because of isolation between VMs:
 Accessing application log files may be a challenge
 Application crash – challenging to retrieve logs
 Logcat etc. – can’t be used from 4.1 Jelly Bean
 Rooting
 USB cable + Android Developer Tools / SDK Tools
 Screenshots:
 Power + Volume Down buttons
 Power + Home buttons
 Swipe Right
 Special applications from Google Play Store
 ADB – Android Debug Bridge
 Screen Sharing – Samsung Screen Share app?
Getting information required for testing

 Non-intuitive Android features:
 Changing orientation => restarting application with
cached data
 Long operations should be asynchronous, e.g.:
 SD card I/O
 Network requests
 What happens when an application tries to launch
several asynchronous operations?
 Using default serial execution for asynchronous
tasks since Android 3.2 Honeycomb, API level 13
 WiFi Internet access with browser password
 Strict mode
Android quirks and main test ideas

 Accessing application data:
 UNIX file system
 File Management
 Windows Explorer / Mac Finder
 Astro File Manager
 Android Developer Tools / SDK
 SQLite – the most widely used Database
 “SQLite Manager” add-on for Firefox
Files and Data

 Why there is no Stop button
 Why my application was stopped by Android
 List of recent applications
 Force stop
Stopping an Android application
