react-testing-library VS Next.js

React Testing Library

After searching for a workaround, I found this issue thread on the React-testing-library Github page, which gave me a clear solution.

yeeeesss and as an advice use testID in most of matcher cases. also do not rely only on detox matcher try https://github.com/testing-library/react-testing-library

React Testing Library: This library provides simple and complete React DOM testing utilities that encourage good testing practices. It helps you write tests that are more focused on the behavior of your components rather than the implementation details. https://github.com/testing-library/react-testing-library

I've had a number of issues since the upgrate to React 18, notably this one.

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

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.

^ 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.

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.

Until the time of writing, there is no official example of how to enable runtime environmental variables in a Dockerized Next.js app, as utilizing unstable_noStore would only dynamically evaluate variables on the server (node.js runtime). There is also an interesting discussion regarding this topic on GitHub.

next.js is a very popular React framework. remix-adonisjs includes more functionality through the AdonisJS backend ecosystem, and should be easier to self-host and self-manage.

Remember to start the Next.js server with pnpm dev.

We want to share with you the best testing setup we've experienced - and this includes using Playwright and NextJS. It's a setup we've come up with for Infinite React DataGrid, which is a complex component, with lots of things to test, but this configuration has helped us ship with more confidence and speed.

If you're acquainted with NextJs, the directives will come as no surprise.

Deploying a full-stack Next.js web app can seem complex, but with the right tools, it's straightforward. This tutorial will cover the essentials to get your app up and running quickly:
