If Your Tests Always Pass, You’re Testing the Wrong Thing I’ll admit it — I used to be that developer. I’d write my feature, realize we needed 80% coverage, and then: ✅ Write code ✅ Whip up some JUnit tests that “touch” the code flow ✅ Watch everything pass ✅ Feel good about it 🐛 Ship bugs anyway Looking back, I realize what went wrong. I wasn’t testing my functionality — I was testing to make the coverage report happy. And honestly, if that’s the goal, we might as well skip the tests. Over time, I’ve learned that good tests should be your code’s toughest critics — not its cheerleaders. They should try to break your logic, not just touch it. Now, here’s how I approach writing test cases: ▪️ Instead of asking, “How can I make this line get executed?”, I ask, “What scenario could make this function fail?” ▪️ I start with edge cases that break things, then adjust the code to make them pass. ▪️ I focus less on coverage percentage and more on confidence in shipping. Because the real goal isn’t just a green checkmark — it’s writing code that can survive the chaos of real-world use. Have you ever caught yourself writing “for-the-sake-of-coverage” tests?
