Test-Driven Development (TDD): Benefits, Challenges, and Best Practices
Year: 2025
Type: article
Study design: Systematic Review
Abstract: Test-Driven Development (TDD) is an iterative software development practice emphasizing writing automated test cases before production code implementation. This study explores the benefits, challenges, and best practices of TDD through a systematic review of peer-reviewed literature published between 2000 and 2025. Findings indicate that TDD enhances software quality, reduces defect density, and promotes maintainable code design. However, adoption is hindered by steep learning curves, time overhead, and integration issues. The paper identifies best practices such as developer training, continuous integration, and test refactoring to maximize TDD effectiveness. The study concludes that TDD is a valuable approach when properly implemented, contributing to sustainable and high-quality software systems.
