Summary
In this chapter, we covered testing for React applications using the React Testing Library in combination with Jest. Both packages are a great resource for any developer that wants to add test scripts to their application, and they work very well with React. The advantages of having tests for your application were discussed in this chapter, and hopefully, you now know how to add test scripts to any project. The differences between unit tests and integration tests were shown, and you've also learned how to write end-to-end tests with Cypress.
Since the application that was tested in this chapter has the same structure as the applications from previous chapters, the same testing principles can be applied to any of the applications we've built in this book.
The next chapter will combine a lot of the patterns and libraries we've already used in this book, as we'll be creating a full-stack e-commerce store with React, GraphQL, and Apollo.
