Top 5 React Native Testing Tools Booming in 2020–21
Today, more and more businesses are inclined towards react native due to the innumerable benefits it offers. React native apps have completely changed the mobile app development process but the performance of the app remains extraordinary as before.
Cross-platform app development with react native will save a huge amount of time and money.
With the increase in react native app users, it is crucial for the react native app developers to build an app without bugs.
But everything comes with their own set of challenges. React Native development services even face a few sets of challenges. And, to deal with those challenges there are react native testing tools available.
In this article, we will be talking about a few popular react native testing tools that will enhance your development process. But before that, let us first go through a few types of mobile testing that most of the react native app development companies follow.
Types of Mobile Testing
Unit Testing: A simple testing process which includes testing of javascript methods and objects.
Component Testing: Testing of each component of a project functionally as well as visually.
Integration Testing: Here, a bunch of units for a component are tested together as one entity.
Functional Testing: A kind of black-box testing that focuses on user interaction and requirements.
Best React Native Testing Tools
