JUnit -如何用不同的参数测试同一方法中的重复指令？

import org.junit.jupiter.api.Test;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class MyTest {

    @ParameterizedTest
    @CsvSource({"1, 2, 3", "4, 5, 9", "7, 8, 15"})
    public void testAddition(int a, int b, int expectedSum) {
        Calculator calculator = new Calculator();
        int result = calculator.add(a, b);
        assertEquals(expectedSum, result);
    }
}

class Calculator {
    public int add(int a, int b) {
        return a + b;
    }
}
