Test Driven Development Lab Assignment
For each of the following iterations, write just enough code to pass the test while meeting the principles of TDD. Include the code for each iteration and indicate if it 1) compiles and 2) passes the test

Iteration 1 - Example
public void testPrimeNumber(){
    MyNumber n = new MyNumber();
}

//You include this after every iteration.
import static org.junit.Assert.*;
import junit.framework.TestCase;
import org.junit.*;

public class MyNumber extends TestCase {
}
COMPILES AND PASSES (You include this after every iteration.)

Iteration 2
public void testPrimeNumber (){
MyNumber n = new MyNumber();
n.setValue(7);
assertEquals(0, n.isPrime());
}

Iteration 3
public void testPrimeNumber (){
MyNumber n = new MyNumber();
n.setValue(7);
assertEquals(0, n.isPrime());
n.setValue(10);
assertEquals(-1, n.isPrime());
}

Iteration 4
public void testPrimeNumber (){
MyNumber n = new MyNumber();
n.setValue(7);
assertEquals(0, n.isPrime());
n.setValue(10);
assertEquals(-1, n.isPrime());
assertEquals(“10 is not Prime”, n.printPrime());
}

Iteration 5
public void testEvenNumber (){
MyNumber n = new MyNumber();
n.setValue(3);
assertEquals(-1, n.isEven());
n.setValue(2);
assertEquals(0, n.isEven());
assertEquals(“2 is Even”, n.printEven());
}

Final Step
Write a JUnit test case for printing the factors of a number, and then write the code to pass the test.
