I don't understand what the question is asking for. I can call the "deduct" function. What is it talking about?
package com.teamtreehouse.vending;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
public class CreditorTest {
private Creditor creditor;
@Before
public void setUp() throws Exception {
creditor = new Creditor();
}
@Test
public void addingFundsIncrementsAvailableFunds() throws Exception {
creditor.addFunds(25);
creditor.addFunds(25);
assertEquals(50, creditor.getAvailableFunds());
}
@Test
public void refundingReturnsAllAvailableFunds() throws Exception {
creditor.addFunds(10);
int refund = creditor.refund();
assertEquals(10, refund);
}
@Test
public void refundingResetsAvailableFundsToZero() throws Exception {
creditor.addFunds(10);
creditor.refund();
assertEquals(0, creditor.getAvailableFunds());
}
@Test
public void happyPath() throws Exception {
creditor.deduct(10);

funds -= money;

return refund;

return funds;

2,739 PointsAh, I found it. Just needed to apply the (expected = ...) after @Test

2,739 PointsI don't understand the purpose of the "happy path" test. Is it not just to call the "deduct" function? What else is it asking for? Take a look at the deduct method in the Creditor class. Pay attention to the NotEnoughFundsException that is thrown.
Can you please write a happy path test for us in the CreditorTest fixture using the expected element (parameter) for the @Test annotation? Thanks!
