Question

Does test3() need an assert statement? Why or why not?

public class Test {

private List list;

@Before public void setUp() {

list = new ArrayList();

}

@Test public void test1() {

list.add ("empanadas");

assertEquals ("[empanadas]", list.toString());

}

@Test public void test2() {

list.add ("dumpling");

list.add ("gnocci");

assertEquals ("[burrito, gnocci]", list.toString());

}

@Test (expected = NullPointerException.class)

public void test3() {

Min.min (list); // min() returns the min element

}

Answer : Yes, we would require assert statement.

Explanation:

@Test(expected = NullPointerException.class)

It means that the function inside the test3 can return null pointer exception for which the test should not fail .

Min.min is the function inside test class for which we should add assert statement if the function correctly returned the min element.

So we need assert statement for it.
