Cucumber Framework: A Complete Guide to BDD Testing Tool for Automation Great 2025

 📌What is Cucumber Framework?

Cucumber Framework: Cucumber is an open-source testing tool that supports Behavior Driven Development (BDD). It allows teams to write test cases in a plain English-like language that is understandable to all stakeholders — including business analysts, product owners, developers, and testers.

Originally developed in Ruby, Cucumber now supports multiple languages such as Java, Scala, Groovy, and more. It bridges the communication gap between technical and non-technical members by promoting collaboration and clarity in software development.

📌 How Cucumber BDD Works in Automation

Cucumber Framework: Let’s consider an example to understand how BDD testing works in Cucumber. Suppose you are developing a Funds Transfer module in a Net Banking application. Below are a few scenarios:

• ✅ Fund transfer should succeed if the source account has sufficient balance
  
• ✅ Transfer should happen only if the destination account details are valid
  
• ✅ Security credentials (e.g., RSA code, password) should be validated
  
• ✅ Transfers should process even during bank holidays
  
• ✅ Fund transfer must allow scheduling for future dates
  

In traditional testing, developers write code first and then test it later, often under time constraints. This can result in poorly tested features.

With Cucumber BDD, test cases are written before the code using a specific structure:
Given – When – Then.
This method simplifies the test creation process and ensures better test coverage and understanding.

📌 Example of BDD Syntax in Cucumber

Feature: Fund Transfer

Scenario: Successful transfer with valid details

  Given User has sufficient balance

  And valid destination account

  And correct RSA code

  When User initiates the fund transfer

  Then Transaction should be successful

This structure serves as both a test case and live documentation, ensuring everyone understands what the application is expected to do.

📌 Why Use Cucumber Framework?

Cucumber Framework: Cucumber is ideal for Agile and DevOps teams that follow Shift Left Testing practices. It reduces ambiguity in requirements, promotes collaboration, and improves the quality of deliverables by aligning code development with business expectations from the start.
