Cucumber Framework : Beginner's Tutorial (2025)

Introduction to BDD:

• Behavior-Driven Development (BDD) is a Software Development Methodology that focuses on the behavior of software applications from the perspective of end-users. 

• This means that BDD is primarily concerned with what the software does, rather than how it does it. 

• BDD aims to improve the collaboration between technical and non-technical team members by providing a common language for discussing the application's behavior.

To define the behavior of an application in BDD, we use scenarios. 

• Scenarios are written in a Natural language syntax that describes the behavior of the application from the user's perspective. 

• Scenarios are typically written in a format called Gherkin, which is a plain-text language that is easy to read and understand.

Here's an Example scenario written in Gherkin for a feature that allows users to add items to a shopping cart:

Feature: Shopping Cart
 
  As a customer
 
  I want to add items to my shopping cart
 
  So that I can purchase them later
 
 
 
  Scenario: Adding items to the shopping cart
 
    Given I am on the product page
 
    When I click on the "Add to Cart" button for the product
 
    Then the item should be added to my shopping cart

In this scenario, we describe the behavior of the shopping cart feature from the perspective of a customer. 

The scenario is divided into three steps: Given, When, and Then. 

• The Given step sets up the initial state of the system, 

• The When step describes the action being performed

• The Then step describes the expected result.

Explanation of the Above Scenario: 

• The Given step sets up the initial state by stating that the user is on the product page. 

• The When step describes the action being performed by stating that the user clicks on the "Add to Cart" button for the product. 

• Finally, the Then step describes the expected outcome by stating that the item should be added to the shopping cart.
