The Importance of Functional Testing for Web & Mobile Applications

Mobile devices have become one of the most important forms of communication in the world over the last few years. Their original goal was to simplify communication, but today they are devices with a wide range of uses. They are used for communication, work, entertainment, education, news, etc. Mobile devices used to be a matter of luxury, but today few people do not own one. They have evolved way beyond their primary function, becoming a small mobile computers with their own operating system, many different functions, and applications, and there is a lot of competition among all these applications. Numerous capabilities and the convenience of mobile devices have led to unstoppable growth in the development of mobile applications, and the application market has become one of the fastest-growing industries. The offer of applications is growing every day and today we can find an application for almost anything we want.

Given the fact that competition is high, the importance of apps performing in a good way is huge. This is why we will discuss the importance of their functional testing, in the rest of the article. But first, let’s explain this kind of testing a bit more in detail.

What is functional testing?

It’s a kind of testing that is used to check the correctness of the application, i.e. whether it is doing what it is supposed to do. It can be said that it checks “what the application does”. It is performed by making an action or entry in the application and comparing the result with the expected one. After that, it is assessed whether the result is equal to the expected one if there were any kind of errors in the process. Such testing can be performed as a black or white box, module testing, integration testing, system testing, or acceptability testing

Functional testing is performed having in mind how end users would utilize it. Test scenarios are written taking into account user behavior and their possible expectations of the application and do not include performance testing. Therefore, there is another type of testing, a non-functional one. To know more about how it works click this link here.

All this demand we’ve explained in the beginning has led to an increase in the importance of testing mobile applications. It is important to have an application that works flawlessly and that is better than competing applications, and this can only be ensured by constantly testing the application. Constant testing can be performed manually, but more and more people are moving toward test automation where tests are compiled that are constantly executed during all phases of the application development process and ensure its error-free operation.

There are more reasons why testing is so important…

Speaking of apps, regardless of whether they are designed for smartphones or the web, are just products. So, being what they are, testing is what needs to be done, just like with any other product. It should make sure the quality is according to the standards, and users will actually get what they paid for.

As every product, in the case of an app, aims to satisfy the end-user with its functionality, leaving a positive experience with its performance, anything that can jeopardize it has to be eliminated. What other way to do it, than test the functionality from different angles? So, testing aims for discovering all the flaws that can potentially cause a bad user experience.

By testing from different angles, we mean double checking if it works in different situations the target group will be using the app. For example, does it work while the user is hiking, how many devices can it synch with, etc. As for web apps, it is very important to test how they work on different browsers.

Why is the user’s experience so important?

We live in an era of sophisticated technology, and as we already mentioned, in a market overcrowded with different apps. This means that every user expects perfection, and has zero-tolerance for any bugs and crashes connected to an app. Some research, from GeekyAnts, has shown that almost 50% of people are less likely to use the app twice if they have experienced a crash or some other troubles in functionality. Hence the importance of having a satisfied customer. Because if otherwise, bad ratings given by unsatisfied people can result in fewer and fewer people wanting to use the app. If people do not use it, profit cannot be expected.

Another research has shown that approximately 15% of people will give the app a second chance if they have experienced a functionality error once. For this reason, testing should be done before the official launch, because once launched, if something doesn’t work, the image of the entire company can suffer.

There are a large number of app projects that, unfortunately, fail due to errors in some of the stages of their development. There are even many more projects that have failed than those that have been completed. It is probably because developers were rushing to launch, without understanding the importance of functionality, and how it affects the end-user.

It is clear that the process of ensuring the quality of software in general, and Web software in particular, requires a lot of effort, that there are resources and supporting elements of this process, which are numerous and flexible today. Therefore, the organization dealing with app development has to find a way, to choose the appropriate one from all software development methods, implement and adapt it, and then, in parallel with development, start applying quality standards and software development standards in general.

It is especially important to conduct the testing process from the beginning to the end of the project and at all levels of the designed app solution. The tester is in charge of understanding the functioning of the system as a whole, knowing the answers to questions, and, after all, keeping the balance and reminding that the application is used by ordinary people, who like reports and images, sorting and shortcuts.
