Mobile app testing: tips and tricks

Mobile app testing: tips and tricks

Mobile apps are a rapidly growing segment. They can be installed on tablets and smartphones, the quality of work depends on adaptation to a specific interface. Testing mobile applications has its own characteristics, the basic principles differ significantly from desktop ones. If a competitor’s program performs better than yours, the user will go to him. So you need to invest in development, testing, and application improvements.

Features of mobile apps

Mobile apps have a number of differences from PC apps and should be taken into account when testing. A mobile device is devoid of powerful productive filling, so it will not work like a PC. In order for the phone or tablet not to slow down, the application must be functional and lightweight at the same time. The abundance of visuals contributes to the long run time of the application.

Mobile devices can have different resolutions, and the screen size is always small. Also, after launch, the application should not interfere with the functions of calls (receiving, making calls). Operating systems of phones are quickly becoming obsolete – the task of the developer is to create such software that will work without failures and bugs for more than one year.

Another difficulty in the operation of mobile applications is associated with the constant search for the network by the device, and the data transfer rate can be very different. It’s good if the basic mobile version will load correctly on ios and android, regardless of the internet speed.

Program types

Types of mobile applications that exist today:

Basic mobile – an analogue of a website, opened through a mobile browser on a smartphone or tablet. The development is simple, updates are not difficult, there are no problems with access. Installation on the device for this type of application is not required. There are also disadvantages – lack of support for stand-alone functions, limited functionality, difficulties with redistribution in the App Store and Google Play.

Native – that is, developed strictly for one mobile platform. Autonomous operation is possible, the full list of device functions is activated, the user interface is advanced. For the convenience of users, there are push notifications. The main disadvantage of the solution is the high price; you will also have to regularly invest in software maintenance.

Hybrid – a combined version of mobile and native software. We are talking about displaying site content in a mobile browser in the format of a regular application. Better profitability than native apps, built-in browser, easy distribution. The speed of work is average, the adaptability of graphics to operating systems is also worse than in the previous version.

Testing features

When the design of the application has already been developed, specialists move on to testing, which has a clear strategy. The check itself should be done on a smartphone or tablet – this will give the most accurate results. The order of choosing gadgets:

  1. Analyze market offers, assess customer demand.
  2. Choose top-end devices (in terms of popularity, not price), always with different operating systems.
  3. Pick up gadgets with different screen resolutions.
  4. Compare options for memory size, compatibility, connectivity, etc.
  5. Start testing.

When using a smartphone or tablet is inconvenient or simply impossible, they resort to using simulators. They simulate the functionality, behavior of gadgets, create conditions for the implementation of the full testing process, and allow you to find errors. The disadvantage of the emulator is that it does not copy hardware, it only allows you to configure similar environments. The accuracy of the results decreases.

You can test the performance and features of the application using cloud technologies. They are available, allow you to run programs on multiple systems at the same time, manage operations in the cloud. Scalability is excellent, there are technical capabilities for parallel runs. The security level is mediocre, the dependence on the connection speed is significant.

Although the resources are tested mostly in an automated mode, some manual work is still performed. Yes, they are energy-intensive, but they are as accurate and flexible as possible, and are quite profitable in the short term. Manual testing ideally simulates real user actions. Some operations cannot be performed this way, the checks themselves are slow.

Testing stages

How to test mobile apps in stages:

  1. Checking the documentation is a preparatory stage. Testers receive detailed navigation programs, device screen diagrams, and analyze data taking into account their inconsistency and completeness. Any discrepancies must be resolved prior to commencing development operations.
  2. Conduct functional testing – it is responsible for the operation of applications in accordance with the established requirements. You need to make sure that the program solves the assigned tasks and fully copes with the current functions prescribed in the specifications.
  3. Evaluate usability – that is, the convenience of the application for the user, the clarity of the interface, compliance with the applicable standards. First of all, look at efficiency, efficiency and convenience.
  4. Check the user interface to make sure it meets the specified specifications. We are talking about screen resolution, performance on different devices, correct placement of advertising windows (they should not cover important information).
  5. Calculate performance – a parameter that is responsible for the stability of the solution, indicators of resource consumption, maximum allowable loads.
  6. Ensure an adequate level of security – she is responsible for risks while providing a holistic approach to protecting applications from viruses, hackers, unauthorized access to personal information.
  7. Check the quality of recovery – that is, the ability of the software to recover from failures as a result of software errors, hardware, communication problems. Crash cycles are inevitable, the question is how well a particular program handles them.
  8. Test localization – that is, adaptation of the application to the requests, interests of a specific audience. We are talking about language support, correct translation, correct date format, the presence of separators in numbers.
  9. Check changes – after the initial corrections, the code will be corrected. You need to make sure that they are done correctly and in full.

When this is done, beta testing is performed. It’s about debugging and testing the beta version of the program. It is necessary to identify as many errors as possible in order to eliminate them further.

Certification testing is aimed at checking the compliance of the finished program with the requirements of different operating systems. There is a whole set of rules and regulations, all of them must be followed.

Before testing, you need to carefully study the application, analyze all its features. Do not forget about the differences between mobile and desktop versions, if possible, carry out checks on gadgets running under different operating systems. Emulators and simulators will also provide useful information, but they are just not enough. And the last thing – remember about the human factor, plus don’t automate absolutely everything.

Testing stages


For the mobile application to work correctly, you always need to do testing in order to avoid a number of errors, freezes and other problems. Above, we have already roughly sorted out what you need to pay attention to, but if you want your application to work without errors and bring you profit, and not a headache, you should contact the specialists. Our studio Lampa has been bringing the most complex projects to life for many years! Contact us for advice and we will develop a functional application of your dreams.
