When developing any software product, the whole team strives to achieve the best result, but, as with any process, there may be certain difficulties or even some errors encountered. In order to detect and resolve them in time, the application is tested. This stage allows you to establish the occurrence of errors or inconsistencies early on, to make the product even better and improve it. In order not to miss anything, a checklist for testing mobile applications could come useful.
First of all, it is always necessary to test the main functions of the application - how it works. Functional testing makes it clear whether the application can handleits functions, whether all elements work together, whether there are errors and whether the basic requirements are being met. This is the most crucial type of testing, which should and is always carried out first, which is why you’ll see it in the checklist for testing mobile applications at number one.
In short, it is necessary to check satisfactory operation of all functions of the application. Here it is important to note that it is all the elements and interrelations of elements need to be evaluated, therefore functional testing is divided into four levels:
When the task is to test a mobile application, it is important to pay attention also to non-functional testing. One kind is compatibility testing. The fact is that mobile applications are most often used on a diverse range of devices, and it is very important that the application functions as intended on each of them, regardless of varying parameters. If compatibility testing fails or is not carried out at all (which also threatens the risk of errors and incorrect operation), you risk losing a substantial segment of your audience because they could not use the product from their device. Moreover, it threatens the reputation of your company.
Cross-platform testing is the most important subtype of compatibility testing, but it has its own specific features. It is essentially checking whether the application works just as correctly on different platforms: Android, iOS, Blackberry and so on. Of course, you only need to check those systems that are used by the target audience of your application, there’s no need to waste resources on checking irrelevant situations.
However, this subtype of testing does not apply to all applications. There are three types of applications: web applications, native and cross-platform (hybrid). Web applications run in browsers, so there is no need to check their compatibility with the platform, it is more important to pay attention to cross-browser compatibility. Native applications are designed specifically for one platform, tested exclusively on it, and do not require cross-platform testing because they are not intended for installation and use on other platforms. Cross-platform applications are created for several platforms at once, and here it is very important to pay attention to adequate testing.
It is necessary to check the correctness of the entire cycle of user interaction with the application: installation, opening, use according to various scenarios, removal and even re-installation.
On these grounds, it is important to pay attention to all other types of non-functional testing: the application must have access to the necessary device resources, provide the proper level of security, display correctly and demonstrate a sufficient level of performance regardless of the system.
Security is one of the most important factors for the user when deciding to use any software product. It is important that no user data is threatened and that the system cannot be hacked and used against itself by attackers.
When testing, often only the most important aspects are selected, and some steps or stages can be skipped to save time. Indeed, on small projects, careful verification of all levels and characteristics can take longer than the entire product development itself. Security testing, however, is not something that can be neglected.
To ensure complete security, when testing the application, pay attention to three key aspects:
Another stage of testing is checking the localization and globalization of the application. This type of testing is also not mandatory for all applications, as some are designed exclusively for a particular audience, whose membersare in one place and have no significant differences between each other. If your application is designed for a wider audience, however, or you claim to be global, you need to devote time to localization.
Each location, like its residents, has certain features that distinguish it from others and should be taken into account when developing the application:
Another significant aspect that needs to be tested regardless of the scale and characteristics of the application is its usability. The importance and impact of User Experience on the fate of the application is a topic that has been mentioned many times. However, in testing, this is a separate category that go unmentioned. The fact is that the user should easily and conveniently get used to the application and perform targeted actions smoothly, otherwise they will not use your product. Your task is to make sure that your audience can do what they installed the application for without spending hours figuring it out.
When speaking about the usability of an application, it is necessary to mention several points to check:
Another important criterion in the operation of the application is its performance. The corresponding type of testing checks how successfully the software product works under different types of load. Performance testing eliminates the risks that your application will not cope with an expected number of users or could crashif they become slightly too much. A simple example - Black Friday is a day of big sales and many purchases, and therefore masses of buyers. At this time, the number of users may increase so much that it is difficult for the server to process all incoming requests. Performance testing will help to prepare for this.
There are several important subtypes of performance testing that allow for the most comprehensive evaluation:
This subtype of load testing is used to see how your application will behave in a critical situation, as well as how quickly it can return to service when the load is reduced back to normal levels.
When conducting stress testing, it is important to pay attention to the maximum capabilities of the system for each type of performance:
With each of them, look that performance indicators return to normal if the load is returned to normal.
Mobile App Testing is a mandatory and completely necessary stage in application development if you want to achieve optimum results. Detection and correction of errors is not the only task of testing. It is necessary to pay sufficient attention to all functions, as well as non-functional characteristics of software products, then testing can provide an in-depth review..
To make sure that you have checked everything you need and did not miss anything, use a checklist, keeping in mind that testing mobile applications requires accuracy and care.
