Ruby Cucumber Training : Introduction to BDD and
Cucumber
What is BDD?
Ruby Cucumber Training : BDD stands for Behaviour-Driven Development.
BDD was conceived by Dan North in 2003
BDD uses natural language to describe the “desired behavior” of the system, that
can be understood by both the developer and the customer.
Gives us an opportunity to create test scripts from both the developer’s and the
customer’s prospective as well.

What is Cucumber?
Cucumber is a command-line tool. When you run it, it reads in your specifications
from plain-language text files called features, examines them for scenarios to test,
and runs the scenarios against your system. Each scenario is a list of steps for
Cucumber to work through. So that Cucumber can understand these feature files,
they must follow some basic syntax rules. The name for this set of rules is Gherkin.
Why Cucumber?
Cucumber supports Behavior Driven Development (BDD) framework. Cucumber
allows automation functional validation that is easily read and understood.
Cucumber was initially implemented in Ruby and then extended to Java framework.

Capybara
Introduction to Capybara
Capybara is an Acceptance test framework for web applications. It integrates with
Cucumber and hides the details of controlling a browser behind an API. It simulates
how a user would interact with a website.

Introduction to Poltegriest, PhantomJs and Gems
Poltergriest:
Poltergeist is another headless driver which integrates Capybara with PhantomJS.
After registering Poltergeist as the driver in Capybara we need not interact directly
with Poltergeist nor PhantomJS, only with the Capybara API.
PhantomJS:
It is a headless, full featured browser. It is based on WebKit and supports all
important web standards (CSS, JavaScript, …). It is ideally suited for automated
website tests.

Gems:
Ruby Gems is a package manager for the Ruby programming language that
provides a standard format for distributing Ruby programs and libraries. Each gem
has a name, version, and platform.
