To do this, we regularly garden our code as we enhance or add to existing areas of functionality.
We can think of Test-Driven Design (TDD) or specification driven approach because it changes our thought processes regarding how we write software compared to a test-after pattern.
Refactoring and TDD support an emergent approach to designing our software. So, although we still ...
