    One thought on “xUnit Test Patterns: Refactoring Test Code”

    1. I started with some interesting reading - but this was only Preface by Martin Fowler. I stopped reading at 200-th page because it gets too repetitive and makes no sense (just a catalogue with generic programming practices) If you want to learn testing - I would recommend (in order):Michael Feathers "Working Effectively with Legacy Code" (explains WHY to write test and how to achieve it)Roy Osherove "The Art of Unit Testing"Mark Seemann "Dependency Injection in "These guys knows what they are wri [...]

    2. This is a really good 300 page book in 800+ pages. Trying to teach myself unit testing, without a more experienced mentor helping me, I ran into a lot of cases where the suggestions in normal unit testing books and guides didn't seem to work. This book had good solutions for many of those problems.Unfortunately, this book is incredibly repetitive with an unbelievable amount of duplicated content. It was to the point where I could read a new chapter, and for several pages I would swear that I mus [...]

    3. Эта книга была написана автором в тесном сотрудничестве с Капитаном Очевидность. Вдвоем они руководствовались принципом "лишь повторенное трижды есть истина". Как результат книга полна воды, среди которой очень сложно отыскать крупицы полезной информации. Практически ка [...]

    4. Big. It will take you a while. But if you want to go from novice to expert in unit test writing -- and learn more about practical application of design patterns along the way -- then read nearly every page, from cover to cover. Periodically he seems to repeat himself, but it does serve a useful reinforcement purpose. Also seems to serve the purpose of further justifying the price. Along with no effort to prevent pages with three lines of text, these two function to add perhaps another 10% to the [...]

    5. Very solid guide about coding high-quality tests.Being a pattern catalog and a very extensive book, it's better using it as a reference guide or reading it in steps (maybe interleaving it with other books). One issue about being a big pattern catalog is the repetition of samples (and even text) from one pattern to another.But the major disappointment is not mentioning anything about using Builders for creating Test Data and even Test SUTs (I strongly advice reading about that).

    6. Amazing book! A deep dive into the world of Unit Tests and the Refactoring of Test Code. So many valuable principles and patterns that you can use in your daily practice.Every individual who calls themselves a 'Professional Developer' MUST read this book.

    7. This book makes me feel like this practice of cataloguing software patterns is getting out of hand. It started with Design Patterns, a brilliant book that catalogued 9 common software design patterns. It wasn't intended to be exhaustive, just a handful of some of the most useful patterns. Then other books started cataloguing other patterns, in various realms of software. This book catalogues patterns in unit testing, but not just a handful. I counted 68 patterns, including things such as using l [...]

    8. I know a lot about unit testing. I'm a big TDD advocate, and I've learned an awful lot of lessons about effective unit testing over the years. I could easily give a series of talks on the topic of unit testing.And yet, I don't think there's a single thing I know about unit testing that isn't covered in xUnit Test Patterns. This book is the bible of unit testing, unbelievably thorough. Nearly every aspect of unit testing is covered (at least that I know about), categorized into patterns and organ [...]

    9. My primary complaint with this book - it's too big. That's a shame - since there is some good stuff in here that needs to be read.I've seen first hand that 'bad xUnit tests can be worse than having no xUnit tests' - teams sink hours trying to keep their tests green, while the tests are like christmas lights flickering red n green on their own accord.Tests are code - the same rigor n quality procedures need to be applied for tests. If not the tests can cripple and impede development (instead of b [...]

    10. It's the Unit Testing Bible. It's highly informative, it covers almost everything a developer should know about Unit Testing. It's big, but it's a very good time investment if you want to become a great programmer.

    11. A huge tome on everything xUnit. Part 1, the Narratives, explains all the basics and I would recommend reading completely. It gives a great overview of both the test "smells" and the patterns in later sections. Part 2, the Test Smells I think of as Martin Fowler's Refactoring book, except dealing strictly with testing. It's organized very similarly to that classic book. Part 3, the Patterns, is like Fowler's Patterns of Enterprise Application Architecture, except again, only dealing with common [...]

    12. I thought this was a good book, particularly if you're new or somewhat new to automated testing. I was a bit disappointed personally though as I found that what other reviewers have said to be true: the book is about 3x longer than it needs to be.The book is fairly repetitious. You'll find a chapter discussing a subject. Then there will be a section describing that subject as a pattern. Then each of the variations of that pattern (which were already discussed) are discussed again as separate pat [...]

    13. This book is not meant to be read in its entirety, so I did not. The first 181 pages that I did read gave a nice coverage of unit testing with (surprise surprise) a particular focus on xUnit tools. The book moves along in a logical fashion, each chapter building on the previous ones which I consider to be very important. The contained illustrations I didn't care for too much; mostly I thought they were unnecessary for me personally but I can see that others might benefit more from them.After the [...]

    14. This book is definitely the "Unit Testing Bible". It's a great reference book and it covers everything you could imagine about unit tests, which is very valuable. Despite its focus on unit testing, much of the smells, patterns and techniques covered by the book are definitely applicable to automated tests in other levels, such as integration or UI.However, the book is VERY repetitive. If you want to read it in its entirety, be prepared to read the same things all over again for multiple times. I [...]

    15. A great reference book on patterns around testing, not so interesting to read from cover-to-cover. However, when you have a problem with your automated tests, then there is most likely a solution in this book. Many problems you run into with starting test automation are covered. I wish I had read this book years before and would not have needed to make the errors for myself. If you are testing your software with automated tests, then this book is a must-read. Don’t shy away because it has so m [...]

    16. Yes, I read the whole damn thing. There's quite a bit of repetition and a lot of very straightforward stuff, so it was quite quick to read for the most part. I make it a habit to spend 15 minutes at work every day reading a technical book and I could generally get through about 20 pages of this each time.There's a lot of good stuff in there and I've taken on board some of the advice. I'm also going to keep it handy as a reference.

    17. Very good, exHAUSTive overview of the xUnit test space. Meszaros names things that I don't think others name or would agree with his name of, but the distinction between the nuances of testware componentry is unique if nothing else. And he knows his stuff and makes you think, which is exactly what development-focused engineers need when thinking about the foreign land of testing. Well, I guess it's foreign no more :-D

    18. An amazing text on testing. I read the first 200 pages, the narrative, and skimmed the rest of the catalog of patterns. It does a great job of defining a vocabulary for unit testing and really nails down the terminology. The narrative format really brings the language to life, shows how all the terminology fit together very nicely. A must read for anyone doing unit testing with any of the xUnit frameworks.

    19. I got half-way through this on the first go.For me, this really serves as a reference piece instead of a book that you get something out by reading the prose.With as many times as this book is referenced in other pieces that I read though, I think it may become more important for me over time.

    20. Highly informative and reasonably readable. The organization was excellent; several introductory chapters and then a listing of patterns, with a glossary and appendices in the back. Plenty of motivating examples throughout.If you want to make sure your unit tests are as effective as you think they are, read this book!

    21. I reviewed this for IEEE Software. This is a great book for software developers/engineers in the often neglected unit test practice. This book starts with philosophy, principles, and then gets into foundations of unit tests and finally with the catalog of patterns. It also discusses smells and refactoring.

    22. After almost a year, finally i've finished reading this "bible of unit test". i called it bible since this books contains a tons of information on unit test, starting from the basic of it. I recommend this book for every one who want to learn how to write a unit test and also for anyone who want to start practice TDD.

    23. Definitely the best resource I've found to understanding the xUnit framework and how to apply it effectively. This book also has *tons* of information. It took me the better part of the year to get through it all (although I was reading it in 15 minute intervals).

    24. An exhaustive essay about unit testing.I really love this book because I learned so much,event if it's sometimes somewhat tiring to read due to many repetions because the book is desiged as a reference book.
