Mobile Application Testing – Essentials to Effectiveness

As the reign of mobile applications and mobile devices continue, we, as part of this revolutionary trend, have to keep ourselves updated about everything latest in the mobile world, don’t we? Of course we do. We also have to be aware of everything we need to in this regard. I’m talking about mobile applications and their making. Continuing my endeavour to make you guys acquainted about the many processes and resources that go into making a mobile application, here I’m going to give you some more information on mobile application testing.
In one of my previous articles, A winning mobile testing strategy: The Way to Go, I had explained the various steps involved in the process of testing and the article, and Mobile Application Testing: Challenges and the Solution had the major challenges faced by testers.
Now, for those of you who read through the testing process, in case you are wondering “what other kinds of testing are there?”….

Here is a list of the most commonly used kinds of mobile application testing. Do keep in mind that all of these tests are conducted to perfect different aspects of an application. Hence, ideally a combination of some of these would probably be the best way to go.

• Functionality testing – This is actually the most basic kind of testing for any application, as it ensures that the basic functions of the app work as intended. As is the case with any user interface based application, mobile applications work on the basis of several human interactions as well. All of these functions need to be tested for their accuracy. Considering the challenges faced by testers, like the wide range of mobile devices for example, functionality testing is usually a time-consuming and intensive process if it is done manually. However, there are various automation tools available in the market for functional testing as well.
• Usability testing – This is conducted in order to ensure that the mobile app is easy to use and provides a good user experience to the customers. It basically tests the app from three angles:
  Satisfactory user experience – The user acceptability level or comfort level of the application and also others affected by its use.
  Effectiveness – The level of benefits achieved through the app in comparison to the level of resources expended for it.
  Efficiency – The accuracy of the application in terms of its ability to achieve specific goals in specific environments.
• Performance testing – This covers testing of performance of the application from the client side, server side as well as network. The client side will focus more on things like, responsiveness of the application, user interface elements etc. It also involves testing with different types of data connections, WIFI, levels of battery consumption etc. There are again a number of tools available to carry out testing in these areas.
• Compatibility testing – This is conducted to see whether the application works as intended in different devices, Operating systems and their different versions, browsers and screen sizes.
• Security testing – This is carried out to test whether the application is capable of storing and protecting information.
• Memory testing – This is important to ensure that the application maintains optimum memory usage throughout its life. Mobile devices usually tend to have very limited memory and the operating systems also have a tendency to stop applications that use too much memory, which might lead to problems with user experience.
• Regression testing – This is done in order to bring to light any bugs or errors that may exist in already built modules of a project after making changes such as improvements, enhancements or configuration changes and the like.

There are also other kinds of testing, like services testing, user interfaces testing, operational testing etc. which are also done in some cases depending on the kind of mobile application. Apart from that, the most commonly used tests are listed above. As a general rule, functional testing is often conducted first followed by performance testing and the rest. Like i said before, not all of these tests might always be conducted in order. It all depends on the application. The basic point is that testing is a huge and significant part of mobile application development, and at no cost can this be avoided.
