How do you test code that uses java

Testing Java code can be accomplished using various frameworks and tools that allow developers to ensure their code functions as expected. A common approach is to use JUnit, a widely-used testing framework in the Java ecosystem, for writing and running repeatable automated tests.

Here's a basic example of how to write a simple unit test using JUnit:


        import org.junit.Assert;
        import org.junit.Test;

        public class CalculatorTest {
            @Test
            public void testAdd() {
                Calculator calculator = new Calculator();
                Assert.assertEquals(5, calculator.add(2, 3));
            }
        }
