Hi, there!
As a mobile developer, I was always concerned about app quality, and the number of unit/component tests in your app will boost its stability.
To make things easier, I built up a repository (check it out) with jest initial configs, so our playground is ready to go. However, read all of the instructions below to fully get what’s going on.
- Testing Library
Jest is installed by default in new React Native applications, but I prefer to utilize the React Native Testing Library (the name speaks for itself). We need to take the following steps to use this library:
yarn add @testing-library/react-native -DAs we are going to use Jest, we need to add one more dev dependency
yarn add @testing-library/jest-native -DWe’ll also do some navigational testing, so we’ll need to take some extra measures.
Create a setup.js file inside jest folder in root, so we’ll have something like the code bellow inside jest/setup.js
