Testing Lombok-based Classes in Java Lombok simplifies Java by auto-generating boilerplate like getters, setters, and constructors. But how do you **test** classes that use Lombok annotations? Here's a practical guide to unit testing Lombok-powered classes — and when you might want to go beyond relying on Lombok alone. ✅ Lombok Class Example Let’s use this simple class as our example: import lombok.Data; @Data public class User { private String name; private int age; } Lombok generates getName() , setName() , getAge() , setAge() , equals() , hashCode() , and toString() . 🔍 Should You Test Getters and Setters?
