? Exploring Test-Driven Development (TDD) has been an eye-opener! Writing tests before the code forces you to think through functionality and edge cases upfront. It’s a powerful way to build confidence in your code and ensure each feature works as expected before you even start coding.
The concept of writing tests before code might feel counterintuitive at first, but it offers some key benefits:
Recently, my mentor had us walk through some files with pre-written tests. Our goal was to draft functions that met the tests and think through the process and the best approach.
In this exercise, I noticed a pattern: each test had a step to validate the string input. Instead of rewriting the validation logic in every function, I created a simple helper function to handle the validation for all the tests. This not only made my code cleaner, but it also improved efficiency.
TDD opened my eyes not just to writing better code but to thinking more strategically about how I code. It really drives how you can be more efficient in your approach.
TDD follows a simple three-step process often referred to as Red-Green-Refactor:
