Test-driven development guides — write tests first, ship fewer bugs, and design better software.
Testing
Test-driven development has a reputation as a coding technique. Write a failing test. Write the code to make it pass. Refactor. Repeat. That loop is real and valuable, but it starts too late. By the time a developer opens their editor, the most expensive design decisions have already been
Testing
The traditional software testing model was sequential: developers wrote code, then testers found bugs, then developers fixed them. Bugs discovered at the end of a development cycle are expensive — studies consistently show that a defect found in production costs 10 to 100 times more to fix than one caught during
Testing Strategy
Red. Green. Refactor. Three words that, practiced consistently, produce code that is better designed, better tested, and easier to change than almost any other development approach. The debate isn't whether TDD works — it's whether the discipline is worth it for your situation. Key Takeaways TDD produces
