API Testing and Development with Postman: A practical guide to creating, testing, and managing APIs for automated software testing

I really enjoyed reading this well-structured book about REST Assured API Testing, A complete road map to REST API automation using Java and TestNG. It's a great toolbox for everyone who wants to start his test automation journey with API. Lots of interesting examples suitable for all readers, they can adapt them to practice easily while reading the book which gives the reader, the feeling of "attending a workshop" rather than just "reading a book"Last but not least, well explained schema and images to explain the code of each concept plus the details in each step in the code "solving the why". It's direct to the point on each step that it is not easy for beginners in API, to understand them alone for the first time. Thanks for such an interesting book!

Paper quality is not good and have no color images

I have been programming for 30 years, the last six of which were building mobile apps. When I switched to creating APIs, Postman became an essential tool, and this an essential guide to getting the most out of it. The writing is clear, the examples are useful and overall this book is an essential guide to testing and development. Highly recommended.

Don't buy this book. The examples in the book are confusing and misleading, and do not seem to have been subject to any proofreading. The book is full of silly mistakes (saying "left" when "right" is clearly intended) and haphazard false claims ("JavaScript is built to be asynchronous by default"). Code samples are printed with a black background that looks terrible in print. The quality of the writing is poor. The author would benefit from a couple of semesters in a good freshman English course, assuming such courses may still be found. He constantly uses a general "this" without specifying the antecedent. At the start of chapters, he likes to take the reader on a whimsical journey that serves little purpose. In one chapter he tells us, "I rather enjoy the theory of automation." In the context, these musings are fairly ridiculous. I contacted the publisher about some of the errors, particularly in Chapter 3. They initially seemed willing to make some updates. At this point, however, they appear to have lost interest in the matter. The errors I mentioned were corrected in the PDF version, but not the online version. Worst of all, if you purchase the printed version you will get none of the corrections. This book is a book about quality made by people who have no commitment to quality whatsoever. I have purchased a lot of bad computer books over the years, but I think this book is the one. It is the worst computer book I have ever purchased. It is a completely cynical cash grab of a book. I do not think it unlikely that the author banged it out in three weeks, and that the technical reviewer never opened it. I can imagine them objecting to this statement, but really, what possible defense could they present? "Hey, we worked really hard on this book, we're just totally incompetent!" I mean, the evidence of what they did is sitting here before us. There is plenty of good online documentation for Postman, and reading it is much easier than plowing through all the mistakes in this book. I myself am taking this purchase as a lesson to first try to use the online documentation, and to never buy anything from Packt.
