Nowadays, smartphones have become an integral part of our lives. Literally every day, «hardware» is improved and so is the software itself. Mobile application development requirements are growing rapidly and developers have no choice but to satisfy the whims of the user.
Before release (launch), the mobile application must meet all the standards and criteria that were previously set, have full functionality, as well as high quality so that the product can compete with other similar applications. This is the purpose of testing and is to ensure product quality.
The article will describe the most common defects that occur in mobile applications during testing.
- If the program does not start within 5-10 seconds after the tap – you need to start writing a bug report. Today's users are very demanding and not always a mobile application can meet their expectations.
- Problems with supporting different versions of OS and devices – the most common bug. The application, designed for a wide audience, should work on both new and old versions of the operating system, as well as perform well on various devices.
- The program does not follow the principles of security and, for example, requests access to the log of calls, messages, photo gallery. This may alarm the user, especially if the application's functionality does not involve the use of personal data.
- Device resource consumption is too high. «Heavy» applications very often «eat» the battery of the device in a matter of hours, which leads to the removal of the application by the user.
- Often applications are not optimized for different types of connections (Wi-Fi, 4G, LTE). In the movement, the quality of communication may change, which affects the performance of the application used, which does not satisfy the user.
- Another part of the application, where you can often observe problems – registration and login forms. According to statistics, in 76% of mobile applications, the main disadvantage is the dangerous storage of personal data.
- Screen resolution is a very important factor, but due to the variety of mobile devices, it can be a problem. A lot of elements of the program interface can break after switching to «landscape» mode.
- Error messages are incomprehensible to the user. For example, due to a bad connection to the server or problems with the device itself, an error code appears. In such cases it is unclear what it means and what to do to restore the application.
- Localization. A lot of applications are designed for the usage on the international markets. In addition to translation, difficulties may arise after changing a time zone. Also, some features of the application that are available for use in the East may be missing in the Western part of the world and vice versa.
Developing and improving mobile applications, it is important to comply with all requirements, be aware of new technologies and experience the product in practice. Testing itself helps to find and fix all the flaws of the program, so that in the end the user is satisfied.
