He book systematically addresses challenges that development teams encounter with TDD from integrating TDD into your processes to testing your most difficult features Coverage includes Implementing TDD effectively getting started and maintaining your momentum throughout the project Creating cleaner expressive sustainable code Using tests to stay relentlessly focused on sustaining uality Understanding how TDD Mock Objects and Object Oriented Design come together in the context of a real software development project Using Mock Objects to guide object oriented designs Succeeding where TDD is difficult managing complex test data and testing persistence and concurren. It took me too long to finish the book First part was uit 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 processBut as soon as I reached actual examples I have lost my interest in reading I found basic examples are already obvious to me More complicated examples over explained and sometimes too difficult to follow the code over and over again Since authors tried to show step by step code transformations it leads to the several blocks of code which are almost the same except minor details To see the difference one would need to proceed reading for the explanation and then go back to the code or scan the code line by line interrupting readingLast two chapter that were mostly about discussing integration testing and advanced topics helped me to finally finish the bookOverall I would recommend this book to anyone who is interested in the art of unit testing in the first place

Foreword by Kent Beck The authors of this book have led a revolution in the craft of programming by controlling the environment in which software grows Ward Cunningham At last a book suffused with code that exposes the deep symbiosis between TDD and OOD This one's a keeper Robert C Martin If you want to be an expert in the state of the art in TDD you need to understand the ideas in this book Michael Feathers Test Driven Development TDD is now an established techniue for delivering better software faster TDD is based on a simple idea Write tests for your code before you write the code itself However this simple idea takes skill and judgment to do well Now there's. 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 uickly 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 make tests readable and maintainable Cons The book is 100% Java How do these lessons apply to other OO languages The authors spend too much time selling the jMock framework The app they develop iteratively is a Java swing app full of distracting details like the way Swing manages threads It was a bit boring at times and the code was verbose so it was easy to lose focus Fun uotesWhat if software wasn t made like we make a paper airplane finish folding it and fly it away What if instead we treated software like a valuable productive plant to be nurtured pruned harvested fertilized and watered Traditional farmers know how to keep plants productive for decades or even centuries How would software development be different if we treated our programs the same wayAs John Gall wrote in Gall03 A complex system that works is invariably found to have evolved from a simple system that works In our work we apply feedback cycles at every level of development organizing projects as a system of nested loops ranging from seconds to months such as pair programming unit tests acceptance tests daily meetings iterations releases and so on Each loop exposes the team s output to empirical feedback so that the team can discover and correct any errors or misconceptionsOne lesson that we ve learned repeatedly is that nothing forces us to understand a process better than trying to automate it Our experience is that when code is difficult to test the most likely cause is that our design needs improving The same structure that makes the code difficult to test now will make it difficult to change in the futureWhen composing objects into a new type we want the new type to exhibit simpler behavior than all of its component parts considered together The composite object s API must hide the existence of its component parts and the interactions between them and expose a simpler abstraction to its peersIn most systems we build we end up writing a runtime exception called something like Defect or perhaps StupidProgrammerMistakeException We throw this when the code reaches a condition that could only be caused by a programming error rather than a failure in the runtime environmentBy repeatedly fixing local problems in the code we find we can explore the design safely never straying than a few minutes from working code Usually this is enough to lead us towards a better design and we can always backtrack and take another path if it doesn t work out One way to think of this is the rock climbing rule of three point contact Trained climbers only move one limb at a time a hand or a foot to minimize the risk of falling off Each move is minimal and safe but combining enough of them will get you to the top of the route

A practical guide to TDD that takes you beyond the basic concepts Drawing on a decade of experience building real world systems two TDD pioneers show how to let tests guide your development and grow software that is coherent reliable and maintainable Steve Freeman and Nat Pryce describe the processes they use the design principles they strive to achieve and some of the tools that help them get the job done Through an extended worked example you'll learn how TDD works at multiple levels using tests to drive the features and the object oriented structure of the code and using Mock Objects to discover and then describe relationships between objects Along the way t. One of best books about software design and TDD and tests in general

    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 foll

    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 classicistSome 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 uickly

    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 wor

    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 reuired to do it but a

    Before reading this book it would be wise to set your worldly affairs in order and prepare your psyche for a transformation which may move you in entirely new and unanticipated directions Not only does GOOS offer a collection of solid practices for any software engineer to follow it also describes a mechanism for design through disciplined planning and execution Many have scribbled on the topic of software dev

    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 spectacularKey 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 buil
