What Is Mobile Application Testing?

The number of consumer and enterprise mobile apps has grown exponentially over the last few years, leaving the end user with a humongous number of apps to choose from. But how does the user choose the app that will take up the precious space on their device? App quality is the key to any app’s success and it can only be achieved through mobile application testing.

App success can be measured by the number of downloads and the positive comments, as well as a rapid implementation of new features and bug fixes. Above all, not be underestimated, word of mouth. But how can you ensure any app success? That is with mobile application testing.

This practice allows you to deliver better software and helps your app to be successful by testing its functionality, usability and consistency, growing your user base.

Mobile application testing is the process every application developed for handheld devices has to go through. This, obviously, is to assure a certain level of quality before an application is released into the market place (app store/ play store). Mobile application development life cycle generally tends to be much shorter than others, hence, heavily depend on mobile application testing for their success. Applications get tested on the basis of security, their functionality, usability etc. This increases the general efficiency of the application on all fronts while also increasing the reliability factor amongst users.

Why is Mobile Application Testing Essentials?

Mobile application testing is very different from software testing and web testing. There are a few specifics that you should consider before performing mobile application testing:

  • website theme designing

    Screen resolution

  • website theme designing

    Turning on/off GPS

  • website theme designing

    Screen orientation (landscape, portrait)

  • website theme designing

    Different devices’ manufacturers

  • website theme designing

    OSs

  • website theme designing

    Type of mobile application

Key Challenges For Mobile Application Testing

  • website theme designing

    Must be downloadable

    The application must be obtainable for the particular platform, generally from an app store.

  • website theme designing

    Diversity in mobile platforms/OSes

    There are different mobile operating systems in the market. The major ones are Android, iOS, and Windows Phone. Each operating system has its own limitations.

  • website theme designing

    Device availability

    Access to the right set of devices when there is an ever-growing list of devices and operating system versions is a constant mobile application testing challenge. Access to devices can become even more challenging if testers are spread across different locations.

  • website theme designing

    Mobile network operators

    There are over 400 mobile network operators in the world some are CDMA, some GSM, and others use less common network standards like FOMA, and TD- SCDMA.

  • website theme designing

    Scripting

    The variety of devices makes executing a test script (scripting) a key challenge. As devices differ in keystrokes, input methods, menu structure and display properties single script does not function on every device.

  • website theme designing

    Test method

    There are two main ways of testing mobile applications: testing on real devices or testing on emulators. Emulators often miss issues that can only be caught by testing on real devices, but because of the multitude of different devices in the market, real devices can be expensive to purchase and time-consuming to use for testing.

  • website theme designing

    Compatibility

    It is necessary to test the compatibility; suppose an application can work on the high resolution and it doesn't work on the lower resolution

  • website theme designing

    Should be able to pick up the phone

    While executing the app application should be able to pick up a call.

  • website theme designing

    Variety of mobile devices

    Mobile devices differ in screen input methods (QWERTY, touch, normal) with different hardware capabilities.

Types of mobile application testing

 

Functional testing

Ensures that the application is working as per the requirements. Most of the tests conducted for this is driven by the user interface and call flow.

Laboratory testing

Usually carried out by network carriers, is done by simulating the complete wireless network. This test is performed to find out any glitches when a mobile application uses voice and/or data connection to perform some functions.

Performance testing

Is undertaken to check the performance and behavior of the application under certain conditions such as low battery, bad network coverage, low available memory, simultaneous access to the application's server by several users and other conditions. Performance of an application can be affected from two sides: the application's server side and client's side. Performance testing is carried out to check both.

Memory leakage testing

Memory leakage happens when a computer program or application is unable to manage the memory it is allocated resulting in poor performance of the application and the overall slowdown of the system. As mobile devices have significant constraints of available memory, memory leakage testing is crucial for the proper functioning of an application

Interrupt testing

An application while functioning may face several interruptions like incoming calls or network coverage outage and recovery. The different types of interruptions are:

  • website theme designing

    Incoming and outgoing SMS and MMS

  • website theme designing

    Incoming and outgoing calls

  • website theme designing

    Incoming notifications

  • website theme designing

    Battery removal

  • website theme designing

    Cable insertion and removal for data transfer

  • website theme designing

    Network outage and recovery

  • website theme designing

    Media player on/off

  • website theme designing

    Device power cycle

An application should be able to handle these interruptions by going into a suspended state and resuming afterwards.

  • website theme designing

    Usability testing

    Usability testing is carried out to verify if the application is achieving its goals and getting a favorable response from users. This is important as the usability of an application is its key to commercial success (it is nothing but user friendliness). Another important part of usability testing is to make sure that the user experience is uniform across all devices. This section of testing hopes to address the key challenges of the variety of mobile devices and the diversity in mobile platforms/OS, which is also called device fragmentation. One key portion of this type of usability testing is to be sure that there are no major errors in the functionality, placement, or sizing of the user interface on different devices.

    Installation testing

    Certain mobile applications come pre-installed on the device whereas others have to be installed by the store. Installation testing verifies that the installation process goes smoothly without the user having to face any difficulty. This testing process covers installation, updating and uninstalling of an application.

  • website theme designing

    Certification testing

    To get a certificate of compliance, each mobile device needs to be tested against the guidelines set by different mobile platforms.

  • website theme designing

    Security testing

    Security testing checks for vulnerabilities to hacking, authentication and authorization policies, data security, session management and other security standards

  • website theme designing

    Location testing

    Connectivity changes with network and location, but you can't mimic those fluctuating conditions in a lab. Only in Country non-automated testers can perform comprehensive usability and functionality testing.

  • website theme designing

    Outdated software testing

    Not everyone regularly updates their operating system. Some Android users might not even have access to the newest version. Professional testers can test outdated software.

  • website theme designing

    Load testing

    When many users all attempt to download, load, and use an app or game simultaneously, slow load times or crashes can occur causing many customers to abandon your app, game, or website. In-country human testing done manually is the most effective way to test load.

  • website theme designing

    Black box testing

    Black box testing doesn't include the internally coding logic of the application. The tester tests the application with functionality without peering with internally structure of the application. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.

  • website theme designing

    Crowdsourced testing

    In recent years, crowdsourced testing has become popular as companies can test mobile applications faster and cheaper using a global community of testers. Due to growing diversity of devices and operating systems as well as localization needs, it is difficult to comprehensively test mobile applications with small in-house testing teams. A global community of testers provides easy access to different devices and platforms. A globally distributed team can also test it in multiple locations and under different network conditions. Finally, localization issues can be tested by hiring testers in required geographies. Since real users using real devices test the application, this is more likely to find issues faced by users under real world conditions.

QAIT Lab provide you a facility of mobile testing so that you can get your mobile application tested in very cost effective manner under the supervision of highly experienced and qualified testers.
