golang 프레임워크를 사용하여 단위 테스트를 수행하는 방법은 무엇입니까?

import "testing"

func TestSomething(t *testing.T) {
    // 你的测试代码
}

func Add(a, b int) int {
    return a + b
}

        {3, 4, 7},
        {-1, 10, 9},
    }

            t.Errorf("Add(%d, %d) = %d, expected %d", tt.a, tt.b, result, tt.expected)
        }
    }
}
