Let's be honest: we've all written terrible tests. Tests that break when you rename a variable. Tests that pass when they should fail. Tests that take 30 seconds to run and test nothing meaningful.
The problem isn't that we don't know testing is important. The problem is that most of us learned testing by copying examples that were already bad, or by following tutorials that focused on the mechanics of testing frameworks rather than the art of writing good tests.
BadTests.com exists because sometimes the best way to learn is through negative examples. By seeing what not to do, we can develop better instincts for what to do.
The trick isn't avoiding bad tests entirely—it's recognizing them quickly and having the courage to delete or rewrite them. Good developers aren't the ones who never write bad code; they're the ones who can spot bad code and fix it.
"The best code is no code. The second best code is code that's easy to delete."
