Go语言如何单元测试

package test

import (
"testing"
)

func TestSum(t *testing.T) {
numbers := []int{1, 2, 3, 4, 5}
expected := 17
//15
actual := Sum(numbers)

if actual != expected {
t.Errorf("Expected the sum of %v to be %d but instead got %d!", numbers, expected, actual)
}
}

package test

import (
)

func Sum(numbers []int) int {
sum := 0
for _, n := range numbers {
sum += n
}
return sum
}
