What is the difference between TDD and BDD in Node.js?

What is the difference between TDD and BDD in Node.js?

TDD, or Test-Driven Development, focuses on writing tests before the code, while BDD, or Behavior-Driven Development, emphasizes collaboration and defining behavior through examples.

Can you give me an example of TDD in a Node.js application?

Sure! In TDD, you would first write a test for a function, say add(a, b), that checks if it returns the correct sum. Then, you would implement the function to pass that test.

How does BDD change the way I write tests?

In BDD, you write tests in a more human-readable format, often using tools like Cucumber. You describe the behavior of your application in terms of scenarios, making it easier for non-developers to understand.

Which approach is better for a new project?

It depends on your team's needs. TDD is great for ensuring code quality, while BDD is better for collaboration and understanding requirements. You might even combine both!
