Questions and answers
- Isn’t it enough to have working code?
Sadly not. Code that meets user needs is an entry-level step with professional software. We also need code that we know works, and that the team can easily understand and modify.
- Users don’t see the code. Why does it matter to them?
This is true. However, users expect things to work reliably, and they expect our software to be updated and improved continuously. This is only possible when the developers can work safely with the existing code.
- Is it easier to write good code or bad code?
It is much harder to write good code, unfortunately. Good code does more than simply work correctly. It must also be easy to read, easy to change, and safe for our colleagues to work with. That’s why techniques such as TDD have an important role to play. We need all the help we can get to write clean code that helps our colleagues.
