b) [3 marks] Given the following code , write the results:

public static int add(int first, int second) {

return firstNumber + secondNumber; }

And

The test code:

@Before

public void setUp() {

math = new Math();

System.out.println("@Before - setUp");

}

@Test

public void add_TwoPlusTwo_ReturnsFour() {

final int expected = 4;

final int actual = math.add(2, 2);

Assert.assertEquals(actual, expected);

System.out.println("Test 1");

}

@Test

public void add_TwoPlusfour_ReturnssSix() {

final int expected = 6;

final int actual = math.add(2, 4);

Assert.assertEquals(actual, expected);

System.out.println("Test2");

}

@After

public void tearDown() {

math = null;

System.out.println("@After - tearDown");

}
