Overview of this book

Taking a complete journey through the most valuable design patterns in React, this book demonstrates how to apply design patterns and best practices in real-life situations, whether that’s for new or already existing projects. It will help you to make your applications more flexible, perform better, and easier to maintain – giving your workflow a huge boost when it comes to speed without reducing quality. We’ll begin by understanding the internals of React before gradually moving on to writing clean and maintainable code. We’ll build components that are reusable across the application, structure applications, and create forms that actually work. Then we’ll style React components and optimize them to make applications faster and more responsive. Finally, we’ll write tests effectively and you’ll learn how to contribute to React and its ecosystem. By the end of the book, you’ll be saved from a lot of trial and error and developmental headaches, and you will be on the road to becoming a React expert.

Common testing solutions

In this last section about testing, we will go through some common patterns that are useful to know when testing complex components.

Testing components should now be familiar to you, and you should have all the information to start writing tests for your applications. However, sometimes is not easy to figure out the best strategy to test, for example, Higher-Order Components.

Testing Higher-Order Components

As we have seen in previous chapters, we can use Higher-Order Components to share functionalities between different components across the application. HoCs are functions that take a component and return an enhanced version of it.

Testing this kind of component is not as intuitive as testing simple ones, so it is worth looking at some common solutions together.

Our target component is going to be the withData HoC created in Chapter 5Proper Data Fetching. We will only apply a small variation in the way data fetching is performed.

The withData function has the...
