Symbian OS
• Symbian OS was originally developed by Symbian Ltd, which in 2008 was acquired
by Nokia.

• Symbian OS had almost no UI Layer, Most UI design was made by third parties
– S60 by Nokia
– UIQ by SonyEricsson
– MOAP by NTT DoCoMo

• In 2008 with Nokia acquiring Symbian Ltd. the Symbian Foundation was created and
the three UIs were contributed to it in order to create a Unified Symbian Platform.

Symbian OS - Continue
• Today two streams of Symbian UIs are available.
– Symbian^3 is used by Nokia’s High-end smartphones.

– S60 is used in Mid-Range smartphones.

• It contains associated libraries, user interface, frameworks and reference implementations of
common tools.
• Symbian runs on ARM processors (x86 unofficial).
• Symbian applications are packed in SISX files and requires Symbian Signed certificate to be
commercially deployed on a handset.
• SEMC recently announced that it is deserting Symbian OS to switch to the more popular OS’s –
Android & Windows Phone 7
• Nokia recently announced that it is also deserting Symbian and is about to move to Windows
Phone 7/8 OS for its future devices.
• Note: NTT DocoMo and Fujitsu announced a new Tablet/Smartphone running Windows 7 OS
(Tablet) and Symbian (Mobile) on one platform (Details)

Android OS
• Android is a mobile operating system developed by Google and is based upon a
modified version of the Linux kernel. It was initially developed by Android Inc. (a firm
purchased by Google)

• Its OS versions are usually incremented alphabetically and named upon famous
cookies/cakes
• 1.5 cupcake
• 1.6 donut
• 2.0 éclair
• 2.2 Froyo
• 2.3 Gingerbread
• 3.0 Honeycomb
• ? IceCream

• What is ADB ?

Android – Screen resolution method

• In Android, Google developed a new way of handling different screen
resolutions, in order to save porting time of applications among various of
Android phones
• Basically Android OS divides its screen size to 4 different sizes and 4 different densities and
the platform transparently handles the rendering of the layouts at the actual screen size
• Small, Normal, Large and Extra Large
• ldpi (low), mdpi (medium), hdpi (high), and xhdpi (extra high)

• Detail explanation of how it’s done can be found in a post at TACT/Blogix

Mobile Application Testing - Methodologies

• The testing methodology mostly depends on the type of application.
• There are 3 main mobile applications:
1) Stand alone Taking into account the mobile phone limitations, such
applications shall be tested by Functional tests, Usability tests,
performance tests.
2) Distributed Testing for both client and server side alone and together
is required (e.g- Instant messaging application)

Mobile Application Testing - Methodologies

3) Web based In a Web-based application the client is an Internet browser,
and the main functionality is built on the server-side. Testing Web based
applications require the following type of testing:
• Functional testing
• Compatibility testing
• Content testing
• Performance testing
• Load testing
• Security testing
• Server-side testing (Web server, application
server)
• Database testing

Mobile Application Testing – Proposed strategy

• Do invest in a device emulator
– It’s a well instrumented testing environment, usually more than 1 skin
– Cost effective
– Bypasses real network
– Easy to debug
• Take advantage of a real remote device solution (Nokia, Device Anywhere,
Perfectomobile)
– “Hire” target device/s per hour to perform real device testing as needed
• Don’t completely avoid testing on real device on real network

Conclusion: Seek a solution which combines remote manual testing on real
device, emulated device testing and automation tests wherever possible.

Mobile Application Testing – Porting Concepts
1 of 3

Since there are variety of devices from each OEM, each has different
constraints (Memory, screen size, heap size, form factor, camera, touch
screen, installation path etc.) – it is a must to plan the application to be as
much portable as possible during the design phases.
Not taking into account the devices family and the above constrains will
require massive porting and long development cycles when starting the
deployment
Having configurable pre-compiled options which vary between devices
would ease the porting and enable to use the same code (Mostly) for all
devices, with only per device configuration options

2 of 3

Having more than one “gold” target device during development phase is also
an important requirement
Using automation solution as mentioned earlier and SDK’s is also an
advantage.
There are special application which can provide quite easily the list of
supported features per device (TasePhone Java application e.g.)
Using emulation environments per device is cheap and cost effective during
development
Taking into account the resources used by the application is important (there
are tools who can shrink the entire folder of resources into a small size file
which can be used by the application – BoomFs)

3 of 3
When a new or pre-launched phone should be supported by the application
developers there are few things which should be taken into account:
Phone characteristics (Screen size, OS, memory, form factor, supported features
such as camera and others) Can be retrieved for most phones through GSM
Arena site
How close the phone is to the lead device within a family which is already
supported
If the phone represents a new family this might have implications on the porting
time in opposed to a new member to an existing family
Is there a way to upgrade phone OS to overcome firmware defects (Cables,
contact with the OEM etc.)
It would always be good to have at least 2 devices from this kind to be able to
reproduce defects, compare performance and firmwares.
How the application works in comparison to other apps on the device (Closing
method, events reaction and more)

Mobile Application Testing – Bug Trackers

• There are few free/cheap tools (Clients) which can be installed on your
mobile device and allow you to submit bugs on the fly as you test your
application
– JIRA Mobile client for Android Beta (and soon iPhone)
http://blogs.atlassian.com/jira/2010/05/jira-android-bug-tracking-mobile-phone-
device-20100520b.html
– FogBugs https://www.fogcreek.com/fogbugz/mobile/
• Supports iPhone, Android, Blackberry

Mobile Application Testing – Battery
Consumption
• As mentioned earlier, the battery of the mobile phone is limited and the application
developers must take into account the application battery usage, performance and
take relevant steps and optimizations in order to assure that the application
consumes the minimal battery resources as needed
– There are monitoring tools which can be used to check the battery usage (Not always
specific per application but this can be narrowed to the specific application vendor
needs)
For iPhone

Mobile Application Testing – SDK’s &
Emulator’s

In order to test application developed for mobile, often the vendors would prefer to
use as many devices SDK’s and Emulators to get as close to reality L&F and
functionality before deploying first on device which has limited debugging capabilities
in opposed to the SDK’s

Mobile Trends and Forecast

Mobile Devices Begin to Replace Credit Cards
2011 looks like the year when, in some countries at least, using
your phone as a credit card for lower value purchases will
become a reality. Google recently announced that NFC (Near
Field Communication) technology will be supported in the next
release of Android – 2.3 or “Gingerbread”;
HTC Flyer phone announced to support NFC within a year
Social networking based devices (Recently HTC announced that
they launched social networking specific devices - ChaCha and
Salsa)

Mobile Trends and Forecast - Continue

Smartphones invading the enterprise (Security threats will be big factors in
determining which companies aggressively deploy smartphones)

Mobile OS battles will continue (Android will become the leading Smartphone
platform for at least the next four years, according to the latest data from IDC. The
analyst firm estimates that Android will account for 45 per cent of the global
Smartphone market by 2015, up from under 40 per cent today (30-Mar-11). RIM and
iOS will see more modest growth and a slight fall in overall market share to around 15
per cent

Smartphone and tablet convergence (growing number of Smartphone manufacturers
will feel pressured to introduce tablet computers, and will likely do so this year.
Offering one but not the other will become an intensifying threat to their businesses)

Mobile Trends and Forecast - Continue

Cloud in Mobile – Apple set to launch cloud-based music service
ahead of Google (In this model, people can upload and store all
their music to Apple servers, and launch it from any device or
share it with other users (Using an iTunes account)).
Apple cuts Amazon & Google by signing the music companies
