What is the difference between TDD and BDD?

What is the difference between TDD and BDD?

TDD, or Test-Driven Development, focuses on writing tests before code to ensure functionality. BDD, or Behavior-Driven Development, emphasizes collaboration between developers and non-developers to define how the software should behave.

Can you give me an example of TDD in action?

Sure! In TDD, you would start by writing a test for a function that adds two numbers. You run the test, see it fail, then write the minimal code to pass the test, and finally refactor the code while keeping the test passing.

What are the benefits of using BDD?

BDD promotes better communication among team members, ensures that the software meets user requirements, and helps in creating a shared understanding of the project.

How can I get started with TDD and BDD?

You can start by learning the principles of both methodologies, practicing with small projects, and using frameworks like JUnit for TDD and Cucumber for BDD.
