What is the difference between TDD and BDD in Agile development?

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

Can you explain how TDD improves code quality?

TDD improves code quality by ensuring that tests are written first, which leads to better design and fewer bugs, as developers must think through requirements before coding.

What are some advantages of using BDD?

BDD promotes better communication among team members, ensures that development aligns with business goals, and helps create a shared understanding of requirements.

Are there any tools that support TDD and BDD?

Yes, popular tools for TDD include JUnit and NUnit, while BDD tools include Cucumber and SpecFlow.

Which approach is better for a new project?

It depends on the project needs. TDD is great for ensuring code quality, while BDD is better for projects requiring strong collaboration and clear requirements.
