# Test-driven development (TDD) explained

**[CircleCI](https://daily.dev/sources/circle)** · 6 min read · 28 upvotes · 1 comments

## Summary

Test-driven development (TDD) is a software development process that involves writing tests for your code before you write the code. TDD enhances collaboration, leads to more robust applications, and improves design and architecture. It also reduces long-term costs and increases confidence in code changes. TDD aligns perfectly with the objectives of continuous integration/continuous delivery (CI/CD) by ensuring code quality, enabling early bug detection, and facilitating automated testing.
