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.

Cucumber benefits?

It is an Open Source Tool

Plugin in cucumber works faster

Cucumber supports other language as well beyond Ruby like Java, Groovy, .Net etc.

Involve business stakeholders who cannot easily read code

Cucumber focuses on end-user experience

Style of writing tests allow for easier reuse of code in the tests

Quick and easy set up and execution

Efficient tool for testing

Cucumber supports many

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.

Install Capybara

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:

RubyGems 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.
