-"Of course, I test my apps! I didn't wait for you to tell me that!" 😏
-"Yeah, but..."

Next.js is a framework so powerful, embodying so many different strategies
to fetch data and interact with them, server-side and client-side, that it makes
it the most difficult technology to test in the world.
That's the price of fame!


Of course, you certainly use testing tools like Jest, Vitest, Storybook, Cypress, or Playwright.
This is already covered by Next.js documentation.
But the difficulty lies in using them efficiently.

What to expect from this course?

This Pattern will be dedicated to properly testing Next.js applications., with the new App Router architecture and React Server Components.

  • Learning what strategy is the best for each part of the application you want to test.
  • Learning how to optimize your development process to facilitate quality assurance.
  • Learning efficient debugging patterns for React Server Components.

This course is a collection of best practices for efficient testing and quality assurance of Next.js application based on the App Router architecture and React Server Components.

Each developer on StackOverflow will propose their own little trick to test apps, but they don't explain properly which solution should be used in each specific situations.

Try it out!

Each pattern is an article focused on solving a specific problem.
It includes an interactive code demonstration.
For those who want to practice, each pattern comes with an optional exercise with
a live preview in a web container.
