Again: this is the kind of book that, after having read it, you understand why it is considered "a must".

I can only recommend it. I have never worked with Ruby, but that's not a problem for getting all its value.

On the other hand, I'm really happy that I read it now and not 5 or 10 years ago: I wouldn't have the experience I have now and most of it would have stayed just as "theory" on my mind.

The book contains great advices, reflections and insights about OO and testing. Which doesn't mean that I agree with every perspective, but even the "disagreements" were useful for me.

Than you very much to [a:Sandi Metz|5763434|Sandi Metz|https://s.gr-assets.com/assets/nophoto/user/u_50x66-632230dc9882b4352d753eedf9396530.png] for writing it!
And for the rest of you, just... read it!!! ^___^

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 www.growing-object-oriented-software.com/

To be honest, I didn't grab everything they explain. And after finishing, the imposter syndrome is devastating me: I think I know nothing 0_o '

But it was definitely worthy and I'm sure it has helped me to become a better developer :-)

Very shocking, funny and interesting real stories about the dangers of "not correctly" tested or monitored software systems :-)

Besides the tones of examples, I found very valuable advices to avoid them (e.g. names, dates, unicode, cultural and ethnic differences, etc).

GREAT book with lots of very good insights and advices.

I highly recommend it to anyone interested in facilitating any coding dojo :-)

AMAZING book.

A must for anyone willing to learn more about "Lean". Even if was already familiar with several concepts, this book explains exceptionally well how everything connects, with very interesting information and reflections about the "history" of the buzzy word.

And the "story" is very well written.

I can only highly recommend it :-)
