Test-driven development encourages writing tests before code, leading to more reliable and maintainable software.

Principles of Test-Driven Development

The TDD cycle consists of writing a failing test, producing code to pass it, then refactoring.

This approach builds confidence in code correctness from the start.

Benefits for Teams and Projects

TDD reduces bugs, facilitates safe refactoring, and improves design clarity.

Teams experience faster feedback loops and lower defect rates.

Getting Started with TDD

Begin with small, well-defined units and gradually expand coverage.

Pair programming and code reviews help adopt best practices effectively.

Common Challenges and How to Overcome Them

Initial productivity dips are common but pay off with improved long-term stability.

Emphasizing education and incremental adoption eases the transition.
