Golang之单元测试

文件名必须以_test.go结尾
使用go test 执行单元测试

例

package main

func add(a, b int) int {
    return a + b
}
func sub(a, b int) int {
    return a - b
}

calc.go

package main

import (
    "testing"
)

func TestAdd(t *testing.T) {
    r := add(, )
    if r !=  {
        t.Fatalf("add(2,4) error,expect:%d,actual:%d", , r)

    }
    t.Logf("test add succ")
}
func TestSub(t *testing.T) {
    r := sub(, )
    if r != - {
        t.Fatalf("sub(2,4) error,expect:%d,actual:%d", , r)
    }
    t.Logf("test sub succ")
}

calc_test.go

package main

main.go

运行：

E:\project\src\go_dev\day8\test>go test -v
