What is React Native?
React Native is an open-sourced JavaScript framework for writing real, natively rendering mobile applications for iOS and Android and it was launched by Facebook.
React Native, primarily used for building attractive user interfaces along with user experience that allows JavaScript developers to build native mobile apps and also hybrid apps that provide native-like feel.
Moreover, React Native is currently trending as a cross-platform mobile app development framework.
Reasons to Choose React Native for Mobile app Development?
Listed below are the top 6 powerful reasons that say react Native is the best one.
- It saves Time and Money and thus works under tight budget constraints.
- It uses same code for developing both Android and IOS applications and thus offers cross-platform mobile app development
- React native mobile app development allows you to perform tasks that are complex using simple codes, thus enabling Multiple outcomes and suppleness under one undemanding solution.
- The journey of the developer from transforming a web page to the mobile app is super easy and there is no need for any core developer team to keep accessing the app.
- With less usage of memory, the 3rd party plugins became much easier and it provides smoother run-time.
- React Native is purely focussed on UI design. Hence, it is greatly responsive and its rendering abilities are by far the best.
Different types of testing for React Native apps:
Below are the different types of testing that are carried out for React Native apps in order to achieve the goal of the app without any bugs and issues.
- Unit testing:
This is the very basic kind of testing followed for every mobile app. This includes testing JavaScript methods and objects which are present at the component level.
- Component testing:
Here, it is possible to test each of the react native components functionally or visually. Here, ReactTestUtils is used in order to test React components, that offers a simple framework.
- Integration testing:
The other testing is integration testing. In this testing, a bunch of different units are tested together as a single entity or component.
- Functional testing:
This is a type of black-box testing which mainly focuses on user interactions and requirements. This covers all the user interactions, underlying software the application as an one entity.
Here are Top 10 Best Tools for Testing the React Native Mobile Apps.
