While writing good code is in itself an art, the process of writing code that can be efficiently tested requires extra efforts and commitment on the part of the developers to write clean code that can be repeatedly tested without any hassle.
It is true that practicing TDD improves code production and encourages writing good code that is robust and maintainable. Nevertheless, time spent doing TDD can be wasted and the technique's return on investment might not be obtained if developers involved in software projects write code that is untestable. This can usually be traced to the use ...
