Really? It seems like it's already been replaced. Can you link to where it's not quite deprecated yet? https://github.com/testing-library/react-testing-library/releases/tag/v13.1.0

How to test if a component is rendered with the right props when using react-testing-library?
expect(wrapper.find('FetchNextPageButton').props()).toMatchObject({ query: NEWS\_QUERY, path: "viewer.news"}) So I'm wondering what's the best approach to test it by using React testing library instead.

Next.js Setup | ESLint, Jest, React Testing Library, and Absolute Imports
^ jest for running the tests & @types/jest to help with IDE auto-complete when writing tests. @testing-library/react to render components in the testing environment & test them in a way that tries to mimic how users interact with them. @testing-library/jest-dom for additional DOM-related assertions.

Getting Started with React Cosmos
There are many ways to test component UIs and some testing frameworks help us achieve that, to mention but a few react-testing-library, where we write tests to check what a component has, for example, if we are testing a form component, we will write tests to check it a button is rendered, if there are input and/or select tags, etc and we usually see the results in our terminals but with React cosmos, we have a visual way to test our components (Visual TDD) which makes testing easier.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation
