QA in Mobile Apps

What it really means

Quality is the ability of your product
to be able to satisfy your users
Quality Assurance is the process that
demonstrates your product is able to
satisfy your users
What is
Quality
Assurance?

What is the aim of
Quality Assurance?
When good Quality Assurance is implemented there
should be improvement in usability and
performance and lessening rates of defects

Have you done Quality assurance in real life??

Every piece of software is created by passing
through the phases of

Quality Assurance Testing

What is
Quality Control?
Quality Control (QC) is the implementation of regular testing
procedures against your definitions of quality and more
specifically the refinement of these procedures
◦ Formal use of testing
◦ Acting on the results of your tests
◦ Requires planning, structured tests, good documentation
◦ Relates to output - Quality Circle

Quality Control makes sure the
results of what you've done are what
you expected.
Quality Assurance makes sure you
are doing the right things, the right
way.

Why Is Mobile Application Testing Important?
 App stores reduce the user feedback loop.
 User feedback is both early and frequent.
 Usability and quality is king, when users are quicker than ever to
abandon an application that doesn’t work the first time.
 Users can get updates rapidly and expect seamless updates and
integration.
 Mobile devices are changing quickly and constantly getting new
capabilities and features.

Types of Mobile Testing
 Hardware testing:
The device including the internal processors, internal hardware, screen sizes,
resolution, space or memory, camera, radio, Bluetooth, WIFI etc.
This is sometimes referred to as, simple “Mobile Testing”.
 Software or Application testing:
The applications that work on mobile devices and their functionality is tested.
It is called the “Mobile Application Testing” to differentiate it from the earlier
method.

Types of Mobile Applications
 Native apps: A native application is created for use on a platform like
mobile and tablets.
 Mobile web apps are server-side apps to access website/s on mobile using
different browsers like chrome, Firefox by connecting to a mobile network
or wireless network like WIFI.
 Hybrid apps are combinations of native app and web app. They run on
devices or offline and are written using web technologies like HTML5 and
CSS.

Testing applications on mobile devices is more challenging than testing web apps on desktop due to
 Different range of mobile devices
 Wide varieties of mobile devices
 Different mobile operating systems
 Different versions of operation system
 Different mobile network operators
 Frequent updates

Mobile Application Testing Strategy
1) Selection of the devices – Analyze the market and choose the devices that are widely used.
2) Emulators – The use of these is extremely useful in the initial stages of development, as they allow quick and efficient
checking of the app.
3) Move to test on the physical devices for a more real life scenarios based testing.
4) Consider cloud computing based testing.
Pros:
 Backup and recovery
 Clouds can be accessed from different devices and anywhere
 Cost efficient, easy to use, maintain and update
 Fast and quick deployment
 Web based interface
 Can run the same script on several devices in parallel
Cons
 Less control
 Internet connectivity issues
 Security and privacy Issues

5) Automation vs. Manual testing
 If the application contains new functionality, test it manually.
 If the application requires testing once or twice, do it manually.
 Automate the scripts for regression test cases. If regression tests are repeated, automated testing is perfect for that.
 Automate the scripts for complex scenarios which are time consuming if executed manually.
6) Validate the application on different networks like 2G, 3G, 4G or WIFI.
Mobile Application Testing Strategy Contd….

In addition to functionality based test cases, Mobile application testing requires special test cases which should cover following
scenarios.
 Battery usage
 Speed of the application
 Data requirements
 Memory requirement
 Functionality of the application
