"I have a confession to make.
I don‘t write unit tests for every function I create. I don‘t always follow TDD. And honestly? I don‘t think my code needs it.
Before you come at me with pitchforks — let me explain."
1. Not Every Project Needs a Full Test Suite
If you‘re building a simple calculator, a to-do list, or a small script — do you really need 100 tests?
Testing adds complexity. Sometimes it slows you down for zero benefit.
For small projects, I‘d rather just run the code and fix what‘s broken. It‘s faster.
2. Tests Can Give You False Confidence
You write tests. They all pass. You feel safe. You deploy.
And then it breaks. Why? Because you didn‘t test edge cases. Or you tested the wrong thing. Or your tests were too specific to the implementation.
Tests don‘t guarantee quality. They just prove your tests pass.
3. Integration Over Unit Tests
Unit tests check tiny pieces of code. That‘s fine. But real bugs happen when pieces talk to each other.
I focus more on manual testing, integration testing, and real-world use cases.
I‘d rather test the whole system than 100 isolated functions.
4. Time Is Limited
When you‘re a student, or a junior developer, your time is precious.
I could spend 4 hours writing perfect tests. Or I could spend 4 hours building features and learning new things.
I choose the second option.
5. I Still Write Tests — Just Not For Everything
Let me be clear: I‘m not against testing.
I write tests for critical parts — payment logic, authentication, core algorithms.
But I don‘t test every single function, every edge case, every possible input.
I test what matters.
"I know this article will trigger some developers. And that‘s okay.
Testing is a tool. But it‘s not the only tool. And sometimes, it‘s not the right tool.
If you want to write tests for everything, go ahead. I won‘t stop you.
Just don‘t tell me my code is 'wrong' because I don‘t follow your dogma."
What About You?
"Do you write tests for everything? Or do you pick and choose?
Tell me in the comments — I want to hear your side."
"If this article made you think (or get angry), leave a tip or a like — it keeps me writing honest opinions."
