2. • Why Mobile Testing is Important
• Key Challenges
• App Types
• Test Environment
• Testing Challenges
• Tools
Topics

3. • The Degree of meeting or exceeding the expectation.
• The process concerned with evaluation of software products to:
• Determine if the product satisfy specified requirements.
• Fit for purpose.
• Detect defects.
• Testing Measure Quality.
“ There are a million ways to do something wrong but only one way to do it right.”
Quality & Testing

4. • Software Failures Cost up to
$60 Billion to US economy
• 16.2% completed on time and
on budget
• 31.1% of projects are
cancelled before they ever
get completed.
• 52.7% of projects will cost
189% of their original
estimates

Quality & Testing

5. • A project is said to have failed when :
• Unable to complete in the allotted budget and resources.
• Delivers later than it was decided.
• Unable to meet the requirements.
• Failed projects could be of the following 4 Kinds:
• Failure caused by bad management
• Failure caused by poor team effort
• Failure caused by poor end product
• Failure caused by errors that could have been caught

7. Dumb Phone
•Voice calling and text messaging
Feature Phone
•Additional functions
•Limited or no web access
•Limited ability to run 3rd app

•Advanced computing capability and
connectivity
•Combined mobile phone with PDA
Evolution

8. Penetration

9. • Smartphones are rapidly becoming the primary method of
interaction for consumers and businesses worldwide.
• International Data Corporation (IDC) predicts that 182.7 billion
mobile apps will be downloaded by 2015.
• That’s a 1600%
increase from
the 10.7 billion
apps downloaded
in 2010.
Penetration

10. • Loss of Time & Money
• Damage to business reputation
• Injury or death
• Word-of-mouth
• Mobile testing services should drive 20% - 40% reduction in costs
while improving speed to market, productivity and quality.

Overall Testing Costs

11. • Cost of Quality divided into 2 categories:
• Cost of Achieving Quality :
• Cost of prevention
• Cost of detection
• Cost of Poor Quality:
• Cost of internal failure
• Cost of external failure
Cost of Quality
• A portion of the testing budget is a cost of detection and internal failure
which is typically well below the cost of external failure which is 10 –
1000 times.

18. • CTQs are the internal critical quality parameters that relate to the
wants and needs of the customer.
• CTCs are what is important to the customer.
• What’s CTQ to ensure the things that are CTC.
User Expectation

19. Performance According to a recent study, 60% of mobile users will abandon your
app or site if it doesn’t load within three seconds. Three seconds!
OS & device Having an app available on some devices and not others is a death
sentence in the mobile world.
Security Personal data to remain personal – user expect their apps to be
100% free of viruses, malware and other threats.
Connection
speed
Does your app run the same on 3G, 4G and Wi-Fi coverage.
Data usage Users are wising up to the fact that some apps drain battery faster
than others.
Installation
& launch
Is your application easy to install and launch?
User Expectation - CTCs

21. • Native app
• An app build purely using the components build
using the underlying platform
• Runs on device OS and firmware
• Calendar , Calculator , Camera
• Web app
• Browser app, web capable mobile devices
• It’s a web site which run on Mobile phones
• HTML, java script
• M.facebook.com
• Hybrid app
• Combination of Native and Web apps
• Has cross platform compatibility
• LinkedIN , Facebook

Test Device

26. • Testing on real devices is not feasible and very expensive.
• Mobile emulators and simulators can help developers test their
apps on different devices without having to actually have them on
hand.
• These technologies serve as virtual pieces of hardware that
operate on a PC or laptop.

30. Sourcing
Strategies
• In-House Testing
• Outsourcing Testing
• Beta Testing
• Crowd-sourced Testing
Sourcing Strategies

31. • In-House:
• Pros:
• In-house team makes communication easier
• Professional testers who are tightly integrated into SDLC
• Cons:
• Capacity constraints
• Testing may not match user demographics
• Maintaining adequate collection of mobile devices is
prohibitively expensive
Sourcing Strategies

32. • Outsourced Testing
• Pros:
• Professional testers on demand
• Access to range of devices
• More test types
• Cons:
• Hidden costs
• Not easily scalable
• Challenges in communication and time zone
• Still lab-based testing
Sourcing Strategies

33. • Beta Testing
• Pros:
• No direct costs
• Lives outside the test lab environment
• Range of mobile devices, carriers, OS, locations
• Cons:
• Users are not professional testers
• Provide subjective feedback which cost for the company
• Puts unfinished product in front of customers
Sourcing Strategies

34. • Crowd-sourced Testing
• Pros:
• Lives outside the test lab across real devices, carriers, OS
and locations
• Professional testers who mirror end users
• Access to range of mobile devices & connections
• Cons:
• Direct cost
• Requires communication efforts between testers &
developers
