TDD: No Test? No Implementation.
If you can't write a test, you can't write the code. Test the Requirement First.
Most devs start coding with only a hazy idea of what “done” really means.
You assume requirements are clear.
You assume you understand the edge cases.
You assume QA will catch any gaps.
TDD forces you to confront assumptions before you touch the code.
It’s not about writing more tests.
It’s about clarity, assurance, and focus.
When you know you can test a requirement, you know exactly what success looks like.
And that changes everything — from how you design your interface to how you structure your implementation to how fast you can deliver working software.
⚡Can You Even Test the Requirement?
Before you write code, TDD forces you to ask:
Can I write a test for this requirement?
If you can’t, something’s wrong.
Maybe:
The requirement is vague.
There’s no concrete example.
Nobody knows what “done” really means.
And here’s the uncomfortable truth:
If you can’t construct an example to verify the requirement…
… you’re about to implement something blind.
You might push code that looks correct.
It might even pass code reviews.
And yet… it may fail silently in production.
TDD flips the script.
The first checkpoint isn’t your implementation.
It’s the requirement itself.
No test? No implementation.
That simple rule prevents hours (or days) of wasted effort, wasted code, and wasted frustration.
⚡TDD & ATDD
TDD is amazing at keeping your code correct, but it mostly protects your implementation.
ATDD (Acceptance Test–Driven Development) takes it one step further.
Instead of just asking:
“Can I write a test that proves my code works?”
ATDD asks:
“Can I write a test that proves the system behaves as the user expects?”
It shifts the focus from “my code works” to “the system works for everyone.”
Requirements become executable specifications.
Developers, QA, and Product Owners are all aligned on what “done” really means.
Regression bugs drop, because everyone agrees on the expected behavior before a single line of code is written.
Think of it this way:
TDD protects the code.
ATDD protects the behavior.
If you’re working on legacy systems or teams where QA keeps reporting regression bugs, ATDD can transform the process — turning vague requirements and tribal knowledge into tests that everyone trusts.
