What are some examples of TDD and BDD?

Can you explain the difference between TDD and BDD with examples?

Sure! TDD stands for Test-Driven Development, where tests are written before the code. For example, if you're developing a function to add two numbers, you would first write a test that checks if the function returns the correct sum.

What about BDD? How does it differ from TDD?

BDD, or Behavior-Driven Development, focuses on the behavior of the application from the user's perspective. For instance, instead of just testing if a function works, you might write a scenario like 'Given I have a shopping cart, when I add an item, then the cart should show the item count as 1.'

Can you give me a specific example of TDD and BDD in a project?

Absolutely! In a TDD approach, you might start with a test for a login function, ensuring it rejects invalid credentials. In BDD, you would describe the user story: 'As a user, I want to log in so that I can access my account.' Then, you would write scenarios to validate that behavior.

Which approach is better for software development?

It depends on the project! TDD is great for ensuring code quality, while BDD helps align development with user needs. Many teams use both.
