What are some real-world examples of TDD and BDD?

Test-Driven Development (TDD) and Behavior-Driven Development (BDD) are widely used in software development. For TDD, a great example is the development of the Ruby on Rails framework, where tests are written before the actual code to ensure functionality. For BDD, a notable example is the use of Cucumber in projects where stakeholders define the behavior of the application in plain language, making it easier for developers to understand requirements.

Can you explain how TDD was used in the Ruby on Rails framework?

Certainly! In Ruby on Rails, TDD is implemented by writing tests for models, controllers, and views before writing the actual code. This approach helps developers focus on the requirements and ensures that the code meets the expected behavior from the start.

What about BDD? How does it differ from TDD?

BDD focuses on the behavior of the application from the user's perspective, using natural language to describe features. Unlike TDD, which emphasizes testing individual units of code, BDD encourages collaboration between developers, testers, and non-technical stakeholders to define how the application should behave.

Can you give me an example of a project that successfully used BDD?

A well-known example of BDD in action is the development of the online shopping platform, where teams used Cucumber to write user stories in plain language. This allowed everyone involved to understand the requirements and ensure that the final product met user expectations.
