Challenge Task 1 of 1

Question

I've started the shell for the @Before fixture for these tests. See how the Arrange part is duplicated in both tests, can you help me fix that please?

Use the @Before method to instantiate a new Calculator and use that instance in each method.

com/example/CalculatorTest.java

package com.example;

import org.junit.Before;
import org.junit.Test;

import static org.junit.Assert.*;

public class CalculatorTest {

    @Before
    public void setUp() throws Exception {
        CalculatorTest = new CalculatorAddNumbers();
    }

    @Test
    public void addingMultipleNumbersProducesResult() throws Exception {

        int answer = Calculator(1 ,2, 3);

        assertEquals(6, answer);
    }

    @Test
    public void addingSingleNumberTotalsAppropriately() throws Exception {

        int answer = Calculator(1);

        assertEquals(1, answer);
    }
}

com/example/Calculator.java

package com.example;

public class Calculator {

    public int addNumbers(int... numbers) {
        int total = 0;
        for (int number : numbers) {
            total += number;
        }
        return total;
    }
}

You need to create a new Calculator object

    private Calculator calculator;

    @Before
    public void setUp() throws Exception {
        calculator = new Calculator();
    }
