What is TDD is best understood when quality and clarity matter from the start. The TDD approach works well when requirements are clear, logic is complex, and the system needs to be stable over time. Teams that clearly understand what is test driven development often choose it for projects where errors can be costly and long-term maintenance is expected. TDD development is the right choice when you want clean code, early bug detection, and confidence while making changes. The benefits of TDD include fewer defects, better design, and easier refactoring. Many teams also prefer it because the advantages of test driven development support faster feedback and safer releases. Conclusion: TDD is the right choice when code quality, reliability, and long-term maintainability are more important than quick, short-term delivery.
