Recommended with reservations.

I came to Test Driven React, Second Edition already comfortable with React, Jest, and Vitest, hoping to sharpen my approach to testing components that interact with authentication systems or data stores – situations common in applications built on platforms like Firebase. I can already test purely presentational components; what I wanted was guidance on designing components to be testable, mocking external interactions, and handling asynchronous flows in realistic applications.

That isn’t the book this turned out to be.

Burnham structures the material around a commit by commit TDD narrative, which is one of the book’s strengths. The progression is clear, and newcomers will likely appreciate seeing the incremental evolution of a component. Unfortunately, every commit message is adorned with gitmoji. While this may be a stylistic flourish for some, the repetition undermines the professionalism of the presentation and distracts from what could have been a clean pedagogical device.

The central example – a carousel component – lands on the toy side of the spectrum. Carousels certainly exist in real applications, but most teams consume them rather than build them from scratch. The more common testing challenge is verifying that such a component behaves correctly when fed data from an external source. The book doesn’t explore that space. Beyond a few mentions of asynchronous behavior, there is no meaningful discussion of mocking strategies, testability patterns, or how to approach components that depend on authentication or remote data.

What the book does spend time on is tooling. ESLint, Prettier, Wallaby, and other parts of the surrounding ecosystem receive substantial attention. These are useful tools, but the emphasis feels mismatched with the title and stated focus. In a book positioning itself around test driven design, I expected these tools to appear as brief contextual mentions, not as major chapters. The inclusion of Wallaby – a commercial tool – felt particularly out of place in a book not dedicated to it. Tooling also ages quickly, which shortens the practical lifespan of material that isn’t core to the book’s theme.

If I were titling the book based on its actual content, something like A Cross Cutting Toolchain for React Component Development would be more accurate.

For beginners in the JavaScript or TypeScript ecosystems, especially those who have never written unit tests before, this book offers a gentle introduction and a coherent toolchain. It’s a solid individual primer. But for developers who already have experience with Jest or Vitest, or who are looking to improve their testing of components that interact with real data or authentication flows, the book will feel thin. Once you strip away the tooling chapters, the actual testing content is quite short.

I read the ePub edition on a Kindle Oasis and encountered no formatting issues. The book is easy to get through – quick, even – but that brevity reinforces the sense that the testing depth is limited.

ACCU readers should come away with a clear expectation:

If you already test React components, you won’t gain much here. If you’re new to React, you’ll learn several complementary tools and how to assemble them, but not how to test the kinds of components that dominate real world applications.
