BDD in Action teaches you the Behavior-Driven Development model and shows you how to integrate it into your existing development process. The Cucumber for Java Book: Behaviour-Driven Development for Testers. John Ferguson Smart is a specialist in BDD, automated testing, and. "BDD In Action" is a book that aims to cover the full spectrum of BDD practices from requirements through to the development of production. Behaviour-driven development (BDD) started as an improved variation on test-driven development, but has evolved to become a formidable.

These are skills that every developer needs to master. But TDD is notoriously hard for teams to adopt effectively without experienced guidance.


BDD begins with the focus on features that deliver business value or what it refers to as capabilitiesbdd in action understandably the next section of the book covers requirements definition using BDD and the important question of ensuring you are building the right thing.

Users need our software to give them the capabilities that bdd in action help them contribute to these business goals. Features are what we deliver to users to support these capabilities.

A feature is a tangible piece of functionality that will be valuable for users Features are expressed in business terms and in a language that management can understand. The book then continues to explain the decomposition of features into manageable chunks user stories for planning bdd in action and the use bdd in action concrete examples to ensure understanding and clarify any uncertainity.

Part 1 First steps

A large section of the requirements definition section is dedicated bdd in action tips and examples of how to write executable scenarios, using both Gherkin and JBehave language formats and how to organise them using feature files and tags before then explaining how these can be automated.

Scenarios describe the high-level requirement Step definitions bdd in action the scenario texts and call the test automation layer to perform the actual tasks The test automation layer interacts with the application under test Using a layered architecture like this is a key part of writing maintainable, readable, auomated acceptance tests.


Section three of the book switches from requirements to a more technical focus on coding and automated testing and provides a number of techniques for code design, unit testing, bdd in action test design, UI testing and testing non-functional requirements.

When you write automated acceptance criteria, using layers can help you isolate the more volatile, low-level implementation details of your tests from the higher level, more stable business rules The Business Rules layer describes the requirement under test in high-level business terms The Business Flow layer The Technical layer represents how the user interacts with the system at a detailed level—how they navigate to the registration page, bdd in action they enter when they get there, how you identify these fields on the HTML page, and so forth.

Interview and Book Review: BDD In Action

The final section of the book bdd in action some of the outputs bdd in action BDD process including living documentation and the continuous delivery process.

The reports generated by the automated tests First and foremost, BDD reports document and describe what the application is expected to do, and they report whether or not the application actually performs these operations correctly.

Overall, this is a very balanced book that bdd in action the reader on the journey from the initial conversation through the requirements, development and testing phases of feature development.

A must read for everyone starting out with the idea to do BDD but keep your mind open and embrace conversations.

Mar 22, Joe Narvaez rated it liked it Bit repetitive. One of the highlights bdd in action the book for me was chapter 3 which has some good coverage of different techniques for requirements analysis. Whilst it could be argued that these are not really BDD, they are included as good examples on how to ensure you are working on requirements that are adding business bdd in action.
