What it really means

Quality is the ability of your product to be able to satisfy your users

What is Quality?

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.

Mobile Application Testing

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 Strategy1) 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
