The market is filling up with mobile applications more and more. According to Statista, in 2016, the number of app downloads was approximately 140 billion. In 2019 this number increased up to 204 billion and in 2020 this rate is keeping growing on. At the same time, competition among companies is growing too, and users raise their requirements for app quality. Poor quality products vanish from the market, and their owners go bust. That's why mobile app testing is so important because it allows us to predict failures and avoid losses.
So mobile app testing is a process of testing that is conducting in a simulated test environment to ensure its functionality, convenience, usability, and quality requirements.
There are some specific properties of mobile app testing that you should consider and remember:
Various screen sizes can complicate testing
Lack of storage capacity on some devices can lead to an inability to install an app.
Voice control, tapping, pulling, swiping, pinching and various other interaction make up challenges for testers.
Mobile apps can be developed for mobile browsers, as hybrid or native applications, and it's important to design test cases for each kind of app.
Apps can work with and without an internet connection, while for example, desktop apps work only with the connection.
Mobile app testing services provide many helpful techniques. One of them is performance app testing, which testers prefer to skip in time lack condition. But even when you haven't time and resources, you shouldn't avoid this method, because you won't save a budget or time, you rather lose it.
