TDD Guarantees Good Code
Explore how test-driven development (TDD) assists in writing better code by providing immediate feedback on your design and logic choices. Understand that while TDD encourages thoughtful design and testing, it does not guarantee good code alone, leaving critical decisions and creativity to the developer.
We'll cover the following...
Just as there are often overly pessimistic objections to TDD, here is an opposite view:
TDD guarantees good code.
As TDD is a process, and it claims to improve code, it’s quite reasonable to assume that using TDD is all we need to guarantee good code. Unfortunately, that’s not at all correct. TDD helps developers write good code and it helps as feedback to show us where we have made mistakes in design and logic. It cannot guarantee good code, however.
