Nowadays, there is a wide variety of popular mobile devices, but to attract the maximum audience, manufacturers need to be smart about which applications to use in gadgets. Therefore, the primary task here is to present them on many different mobile platforms.

Although native applications have excellent interactivity and are compatible with all devices, they are slowly fading into the background. The reason for this is that it takes a lot of time, effort, and financial costs to create several high-quality products at the same time.

Cross-platform mobile application development, on the contrary, is gaining popularity. This can be explained by the fact that in this case, several platforms use a single code base to create apps. In addition, the final products are almost identical in quality to native applications due to the evolving technical process. But at the same time, the financial costs of creating a project are lower.

Mobile development tools

Now the market for cross-platform application development is rapidly developing. Therefore, the variety of tools is increasing, which allows developers to select the best options to achieve their goals. The list of the most popular tools includes:

1. React Native. The main feature of this tool by Facebook is its open-source code. According to reviews, it surpasses in its capabilities many other popular tools that are used in the development of cross-platform mobile applications and occupies a leading position among them. This structure makes it possible to develop applications that are as similar as possible to native ones for Android and iOS. However, it requires knowledge of React.js and JavaScript to work.
2. Flutter. Although this tool from Google appeared relatively recently, it is already very popular among programmers. According to its creators, the tool is great for developing custom applications for desktop, mobile, and web platforms. Flutter runs on Dart, while fully supporting Java, Swift, and some other programming languages.

What is testing and what is it used for?

Regardless of the tool used to develop cross-platform mobile applications, the final product requires testing. It is necessary to eliminate errors and possible technical difficulties. Its main purpose is to customize the application and ensure its efficiency and uninterrupted use.

It should be noted that testing is a time-consuming and important process. However, today it is possible to automate it using special tools, which can significantly save time and effort to do the work. But even in this case, personal control is required, since this method cannot find all the problems.

Testing usually finds problems with interface consistency and with user expectations. The developed applications should run smoothly on any platform, be user-friendly and fully meet the needs of users.
