Behavior Driven Development (BDD) is a synthesis and refinement of practices stemming from Test Driven Development
(TDD) and Acceptance Test Driven Development (ATDD). BDD augments TDD and ATDD with the following tactics:
• Apply the “Five Why’s” principle to each proposed user story, so that its purpose is clearly related
to business outcomes.
• Thinking “from the outside in” — in other words, implement only those behaviors which contribute
most directly to these business outcomes to minimize waste.
• Describe behaviors in a single notation which is directly
accessible to domain experts, testers,
and developers to improve communication.
• Apply these techniques all the way down to the lowest levels
of abstraction of the software, paying particular attention to the
distribution of behavior, so that evolution remains cheap.

In Gherkin, each line that isn't blank has to start with a
Gherkin keyword, followed by any text you like.
The main keywords are:
• Feature
• Scenario
• Given, When, Then, And, But (Steps)
• Background (Pre-requisites to avoid repetition
across scenarios)
• Scenario Outline
• Examples
Gherkin Primer/101

There are a few extra keywords as well:
• """ (Doc Strings)
• | (Data Tables)
• @ (Tags)
• # (Comments)

Differences Between BDD, TDD, and ATDD
• TDD is rather a paradigm than a process. It describes the cycle of
writing a test first, and application code afterwards – followed by
an optional refactoring.
• TDD doesn’t make any statements about: Where do I begin to
develop? What exactly should I test? How should tests be
structured and named?
• BDD always start with the piece of functionality that’s most
important to your user.
• TDD and BDD have language differences. BDD tests are written in
an English-like language.
• BDD is customer-focused while ATDD leans towards the
developer-focused side of things like [Unit] TDD does. This allows
much easier collaboration with non-techie stakeholders than TDD.
• BDD gives a clearer understanding as to what the system should
do from the perspective of the developer and the customer.
• BDD focuses on the behavioral aspect of the system, unlike TDD
which focuses on the implementation aspect of the system.
• ATDD focuses on capturing requirements in acceptance tests and
uses them to drive the development. (Does the system do what it
is required to do?)
• TDD tools and techniques are usually much more techie in nature,
requiring that you become familiar with the detailed object model
(or in fact create the object model in the process, if doing true
test-first canonical TDD).
• TDD allows a good and robust design. Still, your tests can be very
far away from the users' requirements. BDD is a way to ensure
consistency between requirements and the developer tests.
