False positives in test suites can lead to hidden bugs and unreliable applications. This post highlights several common patterns that result in false positives in Node.js tests, such as using loose equality assertions (`equal()` vs. `strictEqual()`), overly general assertions, shallow equality for deep comparisons, misunderstanding assertion behaviors, forgetting to call matchers, misusing mocks, incorrect use of regex, copy-paste errors, incorrect properties in configuration objects, and misusing snapshot tests. Careful attention to these pitfalls can improve the reliability of your tests.
