In the practice of software projects and software developers there are great misunderstandings about test-driven development (TDD). Most developers do not see or know the difference between JUnit testing and TDD. They believe that TDD is a theoretical, time-consuming testing approach.
TDD is more then testing:
- Proof that your code does the expected thing
- Safety net for (your ongoing) refactorings
- Helps you to separate concerns in your code
- Last but IMHO most important, TDD is the spec of your code
PS: If you think you have to spend more time for the TDD, try it without.
