What is the difference between TDD and BDD?

Question

Accepted Answer

TDD focuses on testing the functionality of individual units of code, while BDD focuses on testing the behavior of the system as a whole.

TDD stands for Test-Driven Development, where tests are written before the code is implemented to drive the development process.
BDD stands for Behavior-Driven Development, where tests are written in a human-readable format to describe the behavior of the system.
TDD is more focused on the technical aspects of the code, ensuring that individual units work correctly.
BDD is more focused on the business requirements and user behavior, ensuring that the system behaves as expected.
In TDD, tests are typically written using testing frameworks like JUnit or NUnit.
In BDD, tests are typically written using tools like Cucumber or SpecFlow, using a Given-When-Then format to describe scenarios.
