Go语言如何单元测试

fun_test.go

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)
    }
}

fun.go

package test

import (
)

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

打开cmd，cd到两个文件夹所在目录,输入go test
