# Understanding Tdd vs Bdd : A Guide For Developers

**[Community Picks](https://daily.dev/sources/community)** · 9 min read · 167 upvotes · 8 comments

## Summary

TDD (Test Driven Development) and BDD (Behavior Driven Development) are two development approaches that emphasize testing and collaboration but have distinct differences. TDD is developer-centric and focuses on code correctness, while BDD is user-centric and revolves around system behavior. TDD involves writing tests before code, whereas BDD involves writing behavior specifications before code. Both methodologies can be complementary, with TDD ensuring technical correctness and BDD ensuring the application meets user expectations. Examples and steps to implement each approach are provided.
