Read & Download · The RSpec Book: Behaviour Driven Development with RSpec, Cucumber, and Friends 105 Ails 3 applications and use companion tools such as Webrat and Selenium to express reuirements for web applications both in memory and in the browser And you'll learn to specify Rails views controllers and models each in complete isolation from the other Whether you're developing applications frameworks or the libraries that power them The RSpec Book will help you write better code better tests and deliver better software to happier user. I have mixed opinions on this book On the one hand there s a lot of solid theory here on the philosophy and practice of TDD and a lot of solid practical instruction in implementing Rspec in a Rails app However the book is so unbearably out of date that trying to follow along with their code is a challenge The early parts explaining Cucumber and Rspec in Ruby script were pretty straightforward with a couple of agonizing syntax differences that took hours of research to discover However toward the end of the book as they started diving into Rspec in an actual application the syntax and approach differed so wildly from the current version that I had to put the book down and follow tutorials on the internet to vaguely reproduce the results indicated Of course the publishers will tell you that you should simply use the same version of Rails and Rspec that the book uses but what good does it do me to learn how to run tests in a Rails app that old Basically solid theory but all of the specifics need to be updated and it s a shame that there isn t a recent book about Rspec

Read & Download · The RSpec Book: Behaviour Driven Development with RSpec, Cucumber, and Friends 105 Mber by developing a simple game using Cucumber to express high level reuirements in language your customer understands and RSpec to express granular reuirements that focus on the behavior of individual objects in the system You'll learn how to use test doubles mocks and stubs to control the environment and focus the RSpec examples on one object at a time and how to customize RSpec to speak in the language of your domain You'll develop R. BDD Behaviour Driven DevelopmentAcceptance Test Driven Planning is one of three practices of BDD Itis an extension of Acceptance Test Driven Development The difference between ATDP and ATDD is simple ATDD specifies thatwe write acceptance tests before we write code but it doesn t specifywhen we should write themATDP specifies that the acceptance tests are agreed on during or pos sibly before but no later than an iteration planning meeting This lets us consider the acceptance criteria in our estimates which improves our ability to plan iterations which is why it s called Acceptance Test Driven PlanningThe Scenario keyword is followed by a string and then a series of steps Each step begins with any of five keywords Given When Then And and ButGiven steps represent the state of the world before an event When steps represent the event Then steps represent the expected outcomes And and But steps take on the uality of the previous step In the start game scenario the And step is a second Then a second expected outcome111 Perhaps you re wondering why we d want to do exploratory testing if we ve already tested the app Well we haven t Remember that BDD isa design practice not a testing practice We re using executable exam ples of how we want the application to behave112 We were able to refactor with confidence because we ran the specs between each step so we always knew right away when we introduced a problem We looked at two structural refactorings in detail Extract Method and Extract Class We also talked about a few specific code smells Temporary Variable Long Method and Large Class121 You Can Always Roll BackThings don t always work out uite this cleanly Sometimes we ll try toexperiment like this and run into failure after failure after failureWhen that happens to you and it will don t let it go on too long before rolling back to the last point at which all examples were passing Then you can proceed forward again in smaller steps125 How Traditional Projects FailTraditional projects fail for all sorts of reasons A good way to identify the different failure modes is to ask your project manager what keeps them up at night It s nice to do this from time to time anyway it helps their self esteem It is likely your project manager will come up with a list of fears similar to ours127 Now because we are responsible adults we have a Testing phase where we test the software to make sure it does what it was supposed to do This phase contains activities with names like user acceptance testing or performance testing to emphasize that we are getting closer to the users now and the final delivery131 The Agile ManifestoWe are uncovering better ways of developing software by doing it andhelping others do it Through this work we have come to valueIndividuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a planThat is while there is value in the things on the right we value the things on the left 136 Getting software into formally controlled environments puts us at odds with the corporate governance structures But if we can t get into production freuently there is arguably little value in all the other stuff It may still be useful for the team s benefit but software doesn t start making money until it s in production Remember we want to be writing software that matters139 Three principles of BDD Enough is enough Up front planning analysis and design all havea diminishing return We shouldn t do less than we need to getstarted but any than that is wasted effort This also appliesto process automation Have an automated build and deploymentbut avoid trying to automate everything Deliver stakeholder value If you are doing something that isn t either delivering value or increasing your ability to deliver value stop doing it and do something else instead It s all behavior Whether at the code level the application level or beyond we can use the same thinking and the same linguistic constructs to describe behavior at any level of granularity144 Many people use the words feature and story interchangeablybut there is a subtle difference A feature is something thatdelivers cohesive value to a stakeholder A story is a piece ofdemonstrable functionality that shouldn t take than a fewdays to implement So the feature is useful from the pointof view of the stakeholder and the story is useful from thepoint of view of the team delivering the feature146 A story consists of a number of components A title so we know which story are we talking about A narrative that tells us what the story is about Acceptance criteria so we know when we are doneRegarding narrative the most common format for this is known as the Connextra format after the company where it was first used as a stakeholder I want feature so that benefit147 We use the slightly artificial structure of givens events and outcomes to describe these scenarios This doesn t mean that every scenario has exactly one Given When and Then in that order Rather it means that each step is either setting something up in a known state a given or exercising some behavior an event or verifying something happened an outcome Trying to do than one of these in a single step usually ends up in confusion

Read & Download · The RSpec Book: Behaviour Driven Development with RSpec, Cucumber, and Friends 105 Behaviour Driven Development BDD gives you the best of Test Driven Development Domain Driven Design and Acceptance Test Driven Planning techniues so you can create better software with self documenting executable tests that bring users and developers together with a common language Get the most out of BDD in Ruby with The RSpec Book written by the lead developer of RSpec David Chelimsky You'll get started right away with RSpec 2 and Cucu. Overall I liked this book However if you have worked with rspec before you re going to end up skimming a lot of this book as the basics are thoroughly covered Also if you don t have a strong background in TDD then I think some of the book s message is lost on you All in all then there s a niche here that limits the appeal of this book On top of that the material will age uickly the cucumber stuff already has and I suspect in a year or two s time the book s content will have some significant gaps or shortcomings Partly due to the nature of the project and partly because you can smell the bleeding edge of design hereThe prose has the characteristic PragProg hallmarks the editors are really good at PragProg I think in that it is simple direct and pleasant to read there s no feeling of being talked down to or suffering through the written euivalent of muzak the authors build through the concepts with some neat examples and give a good feel for the cycle of development that they re expounding There were tips and tricks I learnt as I followed along and the repetition helped cement the learningIn conclusion buy it now read it now or leave it forever is my advice
