Testing library: @testing-library/react-native

Has anyone recently done unit tests in RN using jest and https://callstack.github.io/react-native-testing-library/. I’m struggling to mock all the libraries. The example given in testing-library seems to doesn’t need to mock all the libraries but in my case it throws error. I’ve also added ‘transformIgnorePatterns’ in package.json. Any help or repo would be helpful.

This article offers an overview of React Native testing, but there’s so much more to learn! I encourage you to explore other testing techniques and tools, like Snapshot Testing, Detox, and React Native Testing Library. Choose the ones that work best for your project, and keep learning!

Introducing a new tool means introducing a new workflow. This can lead to lower adoption, as developers need to to get familiar with it in the first place. To prevent that from happening, we've based Reassure on https://callstack.github.io/react-native-testing-library/ API as something React Native developers should be familiar with.

Tests with Jest and React Native Testing Library.

The standard is React Native Testing Library for unit and integration tests, and Detox for E2E tests.

Using our experience from developing the React Native Testing Library, we created Reassure—a performance regression testing companion for React and React Native components. We developed it in partnership with Entain – one of the world’s largest sports betting and gaming groups.

I'm building a React Native application with TypeScript. I'm using React Native Testing Library for my component tests.

I faced the following issue https://github.com/callstack/react-native-testing-library/issues/955. Production build is failed and error points to the library from devDependencies.

In this tutorial, we'll be using react native testing library and the main philosophy of this library is focusing on testing how your application works, instead of its implementation.

Visit the Node.js website and download the latest version of Node.js for your operating system.

Basic knowledge of Node.js and its environment setup. If you don't have Node.js installed on your system, make sure you download and install it from the official Node.js website.

Node.js can be easily installed from its official website. Depending on your operating system, you can choose the Windows, macOS, or Linux version. Node.js packages come with npm (Node Package Manager), which is essential for managing dependencies in your projects.

To get started with Node.js 22.0.0, you can download the latest version from the official Node.js website. For those upgrading from an older version, it is recommended to test your existing applications for compatibility with the new release, particularly if you are using native modules or rely heavily on third-party npm packages.

Node.js (version 10 or higher)

Before we start, ensure that you have Node.js installed on your computer. This is necessary because we will use Node's package manager (npm) to create our Next.js project. If you need to install Node.js, you can download it from the official Node.js website.

Before starting a new project in react, you need to make sure that you have NodeJS install on your system. You can download the latest version of node at https://nodejs.org. Follow the instructions on the node website to do the installation.

Installing Node.js: Download and install Node.js from nodejs.org. Choose the version recommended for most users, unless you have specific needs that require the latest features or earlier compatibility.

You should have Nodejs installed on your laptop and if not, check the Node.js official website, and download/ install the latest and stable release.
