Enterprises are adopting mobility faster than ever

Numbers and types of devices are

changing dramatically

• 1 billion smartphones and 1.2 billion mobile workers by 2013

• Large enterprises expect to triple their smartphone user base by 2015

Mobility is driving the “consumerization” of

IT

• 46% of large enterprises supporting personally-owned devices2

• Billions of downloads from Apple App Store

Increasing demand for enterprise applications

• 20% of mobile workers are getting business apps from app stores today

• 50% of organizations plan to deploy mobile apps by 2012

When every industry is worried about recession, mobility is growing at a supersonic speed

The unique challenges in testing mobile applications

• Diversity in Device Management• Application Usage• UX Design• Network consideration• Application & Device security• Rapid Application Testing

Challenge 1 - Diversity in Device Management

• Different application platforms– Each platform has its own standards, application interface, Programming

languages– Needs to test applications on each platform for each features– Different certification process for different platforms– Increases time, cost, and effort

• Device factors– No standardization of device & form factors– New innovations creating more complexities– Following is a list of the factors that can affect your application behavior:

• Screen size • Android OS versions • CPU

Challenge 2 - Paradigm Shift in Application Usage

• Indoor use

• Application dependent

• Data entry through key-board

• Low or zero interruptions

• Low environmental input

• Information Processing through

normal funnel

• Anytime, Anywhere

• Context Sensitive

• Complex data entry process (key-

pad, touch, voice, etc.)

• High interruptions

• High environmental input

(Camera, voice, etc.)

• Information processing through

an inverted funnel

Challenge 3 – Evolving Usage Patterns and innovations are creating new testing challenges

• No established mobile software usability culture – different for different platforms

• Direct usage of usability principles used in PC based applications

• Impact of smaller form factors on usability • Handling interruptions• Interaction with other native and third party

applications (camera, voice, music players)• Complexity created by gestures, multi-touch and

screen rotation

Challenge 4 - Network Considerations

• Unlike the network landscape of the PC environment, the network landscape of a mobile device may have gateways

• Applications should be tested for their compatibility with WAP-enabled as well as HTTP-enabled devices

• Unpredictable network latency leading to inconsistent data transfer speeds.

• Gateways in a wireless network may act as data optimizers that may result in decreased performance for heavy traffic

Challenge 5 - Application and Device Security Risks that Need to be Tested

• Insecure Data Storage

• Improper Session Handling

• Weak Server Side Controls

• Security Decisions Via Untrusted Inputs

• Insufficient Transport Layer Protection

• Side Channel Data Leakage

• Client Side Injection

• Broken Cryptography

• Poor Authorization and Authentication

• Sensitive Information Disclosure

Challenge 6 – Rapid Application Testing

• In order to deliver the benefits of faster time to market, RAD environments are used for mobile application development.

• Since the time taken for development is reduced by the introduction of RAD tools, builds will be available for testing much earlier

• RAD methodology imposes an indirect pressure on testing teams to reduce the testing cycle time without compromising quality and coverage

• This pressure becomes more when applications are targeted for multiple platforms simultaneously

Test Execution• Use a Weighted Device Platform Matrix method to identify the most critical

hardware/ platform combination to test• Check the end-to-end functional flow in all possible platforms at least once.• Conduct performance testing, GUI testing, and compatibility testing using actual

devices. • Measure performance only in realistic conditions of wireless traffic and user load.• Select the right automation test tool

Suggested Guideline for Tool Selection

• Support for ALL object identification methods• Secure solution• Ability to test devices taken out of a retail store - No

Jailbreak/Rooting• Support for all device functionalities such as

gestures, security alerts, wake and reboot• Plugs-in to existing test environment• Same test should run on different devices
