As an engineer, adopting effective development practices is crucial for delivering high-quality software. One of the most impactful methodologies you can embrace is Test-Driven Development (TDD). Here’s why TDD is essential:

Ensures Robust Code Quality

TDD requires you to write tests before writing the actual code, ensuring that every piece of functionality is verified from the start. This practice leads to cleaner, more reliable code. It reduces the chances of bugs and ensures that new features don’t break existing functionality.

Promotes Better Design

Writing tests first forces you to think about the design and requirements of your code upfront. This results in more modular and decoupled code, which is easier to understand, maintain, and extend. TDD naturally encourages you to follow solid design principles.

let’s make this complicated AF.

Early Bug Detection

With TDD, bugs are detected early in the development process. Writing tests first means you identify and fix issues before they propagate. This reduces the cost and time associated with debugging and reworking code later in the…
