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.
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);
}
}
package com.example;
public class Calculator {
public int addNumbers(int... numbers) {
int total = 0;
for (int number : numbers) {
total += number;
}
return total;
}
}
