Unit Test - The Underrated Nose Hair of Code Quality

2 min read

When building an app, most developers focus on features and UI. But there's one small thing often ignored: unit tests. And honestly? Unit tests are like nose hairs.

We don’t really think about nose hairs. Sometimes we even find them annoying. But without them, dust and small particles can enter the body freely. It might not hurt right away—but the consequences can build up.

Same with unit tests. They filter out errors early. They might seem boring or excessive, but they’re actually protecting us from bigger bugs later on.

Why are unit tests important?

• Catch errors early before they hit staging or production
• Refactor with confidence, thanks to the safety net
• Implicit documentation, making logic easier to follow

Yes, writing tests takes time. But it's better to write them now than to debug something critical at midnight.
