Beyond Legacy Code

What I Created

In this little example, I created four classes: PersonTest, which I used to drive the creation of the Person class as well as the two exception classes, AgeBelowMinimumException and AgeAboveMaximumException.

The Java source code for this Eclipse project is available for download at the Pragmatic Programmers web page for this book.^[47]

Here’s the PersonTest class:

PersonExample/tst/person/PersonTest.java

package person;

import static org.junit.Assert.*;
import org.junit.Test;

public class PersonTest {
        String personName = "Bob";
        int personAge = 21;

        @Test
        public void testCreatePersonWithNameAndAge() {
                Person p = new Person(personName, personAge);
                assertEquals(personName, p.getName());
