Java Unit Testing in Java How to Test Single Assertions Make For Better Tests

im getting two annoying errors that I cant figure how to correct

./com/teamtreehouse/vending/CreditorTest.java:39: error: reached end of file while parsing } ^ ./com/teamtreehouse/vending/CreditorTest.java:38: error: cannot find symbol assertEquals(0, creditor.GetAvailibleFunds());

com/teamtreehouse/vending/CreditorTest.java
package com.teamtreehouse.vending;

import org.junit.Test;

import static org.junit.Assert.*;

public class CreditorTest {

    @Test
    public void addingFundsIncrementsAvailableFunds() throws Exception {
        Creditor creditor = new Creditor();

        creditor.addFunds(25);
        creditor.addFunds(25);

        assertEquals(50, creditor.getAvailableFunds());
    }

    @Test
    public void refundingReturnsAllAvailableFunds() throws Exception {
        Creditor creditor = new Creditor();
        creditor.addFunds(10);

        int refund = creditor.refund();

        assertEquals(10, refund);
        assertEquals(0, creditor.getAvailableFunds());
    }

        assertEquals(10, refund);
        assertEquals(0, creditor.GetAvailibleFunds());
    }

    private int funds;

    public Creditor() {
        funds = 0;
    }

    public void addFunds(int money) {
        funds += money;
    }

    public void deduct(int money) throws NotEnoughFundsException {
        if (money > funds) {
            throw new NotEnoughFundsException();
        }
        funds -= money;
    }

    public int refund() {
        int refund = funds;
        funds = 0;
        return refund;
    }

    public int getAvailableFunds() {
        return funds;
    }

}

Hi Brandon,

  • That "reached end of file while parsing" error is because there is a need for one more '}' at the end of CreditorTest.java, so that the CreditorTest class is properly closed out and contained.

  • The second error is slightly more complicated on the surface, though the solution in this case is also quite simple, fortunately!

"./com/teamtreehouse/vending/CreditorTest.java:38: error: cannot find symbol assertEquals(0, creditor.GetAvailibleFunds()); ^ symbol: method GetAvailibleFunds() location: variable creditor of type Creditor 1 error"

Looking at those notes about symbol and location, what the Treehouse compiler is telling us is that it cannot find a method called 'GetAvailibleFunds' for creditor. The reason for this is a typo (the method's name is getAvailableFunds.)

Thus, the final three lines of CreditorTest.java will be:

        assertEquals(0, creditor.getAvailableFunds());
    }
}

Hope this helps!

I put in the lowercase but nothings changed
