package com.teamtreehouse.vending;
import org.junit.Test;
import static org.junit.Assert.*;
public class CreditorTest {
@Test
public void addingFundsIncrementAvailableFunds() throws Exception{
Creditor creditor = new Creditor();
creditor.addFunds(25);
creditor.addFunds(25);
assertEquals(50,creditor.getAvailableFunds() );
}
@Test
public void refundingReturnsAllAvailableFinds() throws Exception{
Creditor creditor = new Creditor();
creditor.addFunds(10);
int refund = creditor.refund();
assertEquals(10, refund);
assertEquals(0, creditor.getAvailableFunds());
}
