Behavior-Driven Development (BDD) for Testers: A Practical Guide

Behavior-Driven Development (BDD) has become a buzzword in modern software testing and development, and for good reason.

It bridges the gap between technical and non-technical team members, ensuring everyone understands the requirements and expected behavior of the system.

But as a tester, how do you fit into the BDD framework? Let’s break it down.

What is BDD?

At its core, BDD is an extension of Test-Driven Development (TDD) that emphasizes collaboration. It uses plain, natural language to describe the behavior of an application, making it easier for developers, testers, and business stakeholders to stay aligned.

In BDD, requirements are written in a Given-When-Then format:

• Given: The initial context or state.
• When: The action or event being performed.
• Then: The expected outcome or result.

Example:

Scenario: User logs in successfully
  Given the user is on the login page
  When the user enters valid credentials
  Then they should be redirected to the dashboard
