1. Mobile Trends
2. Mobile Platforms
3. Mobile Development Platforms
4. Mobile Apps Testing
5. Practical case sharing

3. Feature phone
• Contains a fixed set of functions
beyond voice calling and text
messaging
• Not as extensive as a smartphone.
• For example,
– offer Web browsing and e-mail, but
generally cannot download apps from an
online marketplace, such as Whatsapp

4. Smartphone
• With built-in applications and
Internet access.
• Advanced application
programming interfaces (APIs)
• Able to run different kinds of
free and paid third-party
applications to have better
integration with the phone's OS
and hardware

21. • Developing multiple mobile apps with single
source code
• Some tools use web standards for development
while some need to use proprietary
programming languages.
• For development tools using web standards,
they work in two approaches.
– generate the codes as embedded web content
within the mobile app (e.g. PhoneGap)
– recompile the web codes into native codes (e.g.
Titanium Mobile)
Cross-Platform Development Tools

22. These tools have some common limitations:
• Most of the tools cannot support all common
mobile OS platforms.
• Although web standards are used by some of
these tools, some advanced features like AJAX
are not supported by tools like MotherApp.
• Performance of mobile apps developed by
these tools may not as good as those
developed by native programming language.
• Most of the tools do not provide API for
interfacing with Bluetooth and video capture.

27. Mobile Testing

28. Mobile App Diversity

29. • Integration with existing Systems
• Accelerated Development
• Performance & Security
• Backward Compatibility
Challenges

30. • Quick swipe (user experience, quit app
scenarios)
• Orientation
• Different devices (resolutions, compatibility)
• No network scenario
• Features Test (esp. cross app cases)
• Stress Test (including server side)

32. Components of Mobile Testing

33. • Mobile emulator provides an easy way for testing
the application without the needs of actual device.
• Emulator cannot perform some hardware related
testing
– onboard camera
– GPS,
– sensors,
– multitouch,
– telephony,
– accelerometer feedback
• Testing with actual device must be conducted
before the application is released.

35. Tool Selection Criteria

36. Some Popular Mobile Testing Tools

37. Mobile Automation – Desktop Based
• Mobile test automation tools are installed on a desktop locally
• Interacts with the mobile devices Through USB connection or
Wi-Fi
• Mobile Apps can be installed & tested on both Emulators and
real devices

38. Mobile Automation - Image vs Object
Recognition

39. Comparison of Mobile Test Tools in Market

40. • Stable Automation Framework
useful across multiple
Platforms
• Use Emulators for Automation
early in the development
cycle
• Use Real device for
automation only to emulate
real time usage
When to plan Automation?

41. 1. Define the automation scope
2. Select the Test Automation Tool suitable for
your application and supports multiple Oss
3. Start by building automation scripts for
smoke testing
4. Gradually build a basic test suite for
regression testing that represents business
critical use cases
How to implement Automation
Tools?

42. • Supports Android applications for
Auotmation
• Robotium RC can be utilized to run
testscripts in a Test Lab setup
Robotium

43. Mobile Infrastructure - Emulators

44. Mobile Infrastructure – Real Devices

45. • Test Early and Often
• Create matrix of Platforms, Device, Network
Connections (2G, 3G, wi-fi, LTE, etc.), Carriers for
Testing (Including different OS versions)
• Test for Performance and Security
• Keep Target Audience in mind while testing
• Tool selection should take into account
emulator and real device support across
platforms

facilitate sharing of content
Setting

52. Map View (with GPS function)

53. • Clinics under the Hospital
Authority
• Clinics / Health Centres
under the Department of
Health
Clinic location

54. • Find the location of the clinic based on the
actual circumstances by the AR function
Augmented reality (AR) function

55. • Top right radar displays the
position and the number of
clinics within a specified range
• Range of the radar can be
adjusted by the bottom bar,
increasing or decreasing the
number of clinics
Augmented reality (AR) function

56. • Different clinic information can be shared
with friends and relatives via Facebook
