Might be some syntax error I'm not seeing but it looks fine
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 {
Calculator calculator = new Calculator();
}
@Test
public void addingMultipleNumbersProducesResult() throws Exception {
int answer = calculator.addNumbers(1 ,2, 3);
assertEquals(6, answer);
}
@Test
public void addingSingleNumberTotalsAppropriately() throws Exception {
int answer = calculator.addNumbers(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;
}
}
