    • I think there's a lot of food for thought in this book. Personally, I can remember reading Martin Fowler's Mocks Aren't Stubs some time ago and concluding that I'd be a "classicist."Some time later, I started working with mocks as a way to isolate unit tests from "slow" dependencies, such as databases, trying to make them run more quickly. I didn't have much success, though, because I was still writing my tests in a classicist style.This book helped open my eyes to how the "mockist" style really [...]

    • Do not read this if you don't wanna know that you are writing your tests all wrong! Introduction is rather slow and uninteresting for someone already testing on day to day basis. Throughout half of the book there is a step by step introduction into the TDD - I did not care that much for this part. Especially in the end it was somehow hard to follow when the code base for the example grows - especially for a non-java programmer.But the last 100 pages with the examples of how to write more maintai [...]

    • A great read for anyone interested in automated testing and TDD. Pros:* Makes a strong case for testing: better design, faster feedback, user experience first, regression, and most importantly, the confidence to make changes quickly. * Includes a nice walk through of an iterative, test driven development process of a small app. * Lots of great examples of how "listening" to tests leads to better design (ie, what the "driven" really means in TDD). * I learned a lot from the discussion of how to m [...]

    • I didn't know what to expect when I picked up this book. In spite of its excellent reviews I feared it was going to be another redundant addition to the mountain of books harping on the virtues of Test-Driven Development (TDD), without adding anything significant to the standard sermon.Nothing could be further from the truth.I read a fair share of technical books, but this book is the only one in years that I immediately began to re-read again after finishing. It is easily one of the most import [...]

    • A definite must-read for professional developers, this book taught me a lot about incrementally building software that's constantly deployable and maintainable - not only the technical know-how required to do it, but also the mentality needed. Reading the book made me realize that my unit testing skills are woefully lacking in comparison, so I'm grateful that it provides extension tips, tricks, and examples that I can study for improvement. But this book covers much more than unit testing, which [...]

    • Even if the book describes some OO concepts, in order to get the most out of it I suggest reading a couple of OO related books beforehand and get a good grasp of things like encapsulation, polymorphism and specially objects collaboration. As the authors state it: one of their main focus when constructing OO software is to think about how objects will send messages to each other rather than their roles, in other words, drive the design from how the moving pieces would collaborate with each other. [...]

    • A must read for anyone willing to learn and understand how to write concise and maintainable tests, and how to grow a code base in an object oriented fashion. The techniques and principles shown in this book are pure gold: walking skeleton, depth of testing, async code testing, data test builders, mocking, single responsibility, only mock classes you own, hexagonal architecture, etc. If you're still in the fence about the advantages of TDD, this is for you. It displays how quick it is to add new [...]

    • OK so now I understand why this book became so popular :-)It's that kind of book that I feel I should reread immediately after finishing it. The part with the worked example is great, but personally I found specially interesting the chapters with insights about OOP design and sustainable TDD.The ideal way to get all the value of this book is to write yourself the worked code as they are doing it. If you don't do it, at least take a look to the code here growing-object-oriented-soTo be honest, I [...]

    • I did not realize how much I still have to learn about writing good object-oriented (OO) code, and about hewing to a tight test driven development (TDD) methodology, before I read Growing Object-Oriented Software, Guided By Tests. My education in OO and unit testing has been largely theoretical, with no time spent directly learning from experienced OO programmers; my best mentor was a COBOL coder. Books like Design Patterns: Elements of Reusable Object-Oriented Software, Patterns of Enterprise A [...]

    • Nejlepší kniha o testování (Unit testy, Integrační testy, Akceptační testy), kterou jsem četl. Autoři-praktici precizně popisují svůj přístup k vývoji a testování aplikací a nevyhýbají se na konci knihy ani doporučením, jak psát složitější testy, které zohledňují existenci více nezávislých threadů v aplikaci, nebo jak si poradit s testy, které testují metody závislé na aktuálním datu a čase, a nechybí ani příklady testů, které musí ověřit výsled [...]

    • Pretty cool book. I wish I had it 6 years ago. Learned quite a few of the lessons they talk about the hard way in those years. I really, really like the emphasis on growing and nurturing a software design. I've seen too many codebases that slowly but gradually went off the rail because of too much pragmatism or simply the lack of a big picture on what the software was supposed to do and how it actually did it. Software teams often don't fail delivering the first version of a software. They fail [...]

    • The person who handed me this book said it was "better than Lasse's book" (Test Driven.) I disagree. One can't compare the two books - Test Driven is meant for beginners and this book is meant for an advanced audience. If you have never written unit tests before, this book is very hard to follow. So put it down, get an intro book and come back. I really liked the emphasis on making the software responsive to change along with separating acceptance and unit tests. The book uses Junit 4.6 and ther [...]

    • It took me too long to finish the book. First part was quit interesting and promising. I enjoyed reading stories from the author's practice as consultants trying to adopt TDD and unit-testing doctrine in real life. It was interesting to read their props and cons particularly because I have seen myself in the same role at my daily job. I have seen or wished to see. So I tried to learn new tricks to convince colleagues and managers to accept unit-testing as necessary part of the development proces [...]

    • I would give 3,5 out of 5. This book has some good complementary concepts that I read on other books in the same topic. However, it lies between a technical and conceptual book, and his writing style is sometimes confusing due to that, because he wanted to avoid technical explanations about technologies he choose, and unless you already know them, it created an extra layer of difficult in the text, taking you out of the main point. And I personally got really bored following the construction of [...]

    • It started a bit slow so I was concerned, but it really kicked off. Wish I'd read this 4 years ago. The guided walkthrough is good but as with clean code would have been better as a screencast. The final chapters on testing are spectacular.Key takeaways:- Focus on the communication between objects.- Ports and adapters architecture to separate the domain.- Proper division between unit, integration and acceptance tests.- Use test builders for complex test setup.- Transactional tests are a hack bec [...]

    • This is the best guide to TDD and emergent design I've read. I have two copies, one of which is permanently loaned out to friends and colleagues.

    • While there was a lot to learn and take away you have to overlook the over architecting that took place in the code.

    • This is an amazing book. I've read some classic books about programming but they seems to be more targeted at beginner programmers. They don't offer so much for developers with some experience (even it is useful to read them to remind yourself about industry basics). On the other hand this book is better for advanced programmers. You will know most of described concepts at least from theory but this book shows useful practical usage. The main part of the book is an example of application develop [...]

    • An absolutely wonderful book on TDD. Really explains the process of writing tests before features both technically and pratically.In the middle of the book the authors develop a Auction Sniper application using Swing using the TDD method and bring the reader through the TDD process every step of the way which is a brilliant idea for a technical book as it explains the concept very well.Don't let the fact that it's a swing app deter you however as this could easily be a web framework or some othe [...]

    • This books does a great job explaining both test-driven and object-oriented development. I liked the emphasis on OOP best-practices - communication between objects, separation of concerns, etc. The books also shows that the overly-abused term "pattern" should not be discarder, because it's a great tool when used properly, with respect to the context and the problems at hand.The book uses Java as an example language, and since I don't use Java in my daily work I was impressed to see how even not- [...]

    • GOOS is one of my all time favourite software development books. It guides the reader towards building a software system through test-driven development. The authors discuss many important techniques such as Acceptance Testing, Encapsulation/Information Hiding, "Tell, Don't Ask", Listening to the Tests, and The Walking Skeleton just to name a few. These techniques are strung together with a real example of how they build an automated auction bidding app. The techniques help the authors build res [...]

    • It’s a nice book to improve your TDD and testing skills. Probably the one you need to read after TDD by Example by Kent Beck and before the xUnit Test Patterns.I’m giving 4 stars because at the time written was probably the best material on the topic. However, I think that now, there is better material about when to mock, testing schools, trade-offs, etc. I even disagree with some parts, such as starting with the end-to-end tests. I prefer to start to start with the Use Case (Interactors or [...]

    • Dit boek was me door heel veel mensen aangeraden en ze hadden gelijk. Het heeft echt mijn visie op softwareontwikkeling veranderd. Aanrader voor iedereen die in een OO taal werkt. Mijn enige verbeterpuntje zou zijn dat in de tekst zelf (het boek is verdeeld in een tekstgedeelte en een heel uitgebreid voorbeeld, wat een heel goed idee is) iets meer mini-voorbeeldjes toe te voegen om bv stellingen te illustreren. Dan hobbel je toch wat soepeler door de concepten heen.

    • Interesting book, but a bit too demanding for me, who lacks experience in both Java, JMock and Junit. A large chunk of the book is a worked-through example. It would have been easier to digest if I had more experience with the technology used. My currently used programming language lacks these tools, so I have to do things more manually.

    • Good book. Read about half of it. Didn't go through pt3: A worked example. Will do this at some later stage.

    • A decent book on why you should test your code and how to do it correctly. Though I didn't care much for the example it did show how test driven development is an iterative process.

    • Came recommended by Kent Beck. The authors wrote jMock. This books explains how they approach writing tests.Well worth the read, whether you're new to TDD or if you're a seasoned practitioner. Part I and II lay out how TDD works and the authors' philosophy with regard to writing software. Many other books describe TDD and the authors are candid when it comes to their personal practices. YMMV. Part III is a very comprehensive case study where they use the practices in anger, that is, trying to ac [...]

    • TDD is hardI finished Growing Object-Oriented Software Guided by Tests (GOOS) this afternoon. It’ a book that I sincerely hope I would have had the patience to read years ago. It answers one deceivingly simple question in software development that has bothered me for a long time: How to practice TDD (Test Driven Development)?When I first heard about the Golden Rule of TDD – “Never write new functionality without a failing test”, I was quite skeptical about it. But after several years bui [...]

    • Growing Object-Oriented Software shows the reader how TDD, done from the inception of a greenfield project, can have a dramatic effect on both the design and correctness of a piece of software. The book covers not only unit testing, but also integration, and end-to-end testing, demonstrating that TDD is effective at every level of granularity. In fact, the examples of integration testing are the strongest aspect of the book, and read like natural language while exercising multiple parts of the s [...]
