golang 对私有函数进行单元测试的实例

import (

 "testing"
)
var XXFunc = yourPrivateFunc
func TestXXFunc(t *testing.T) {
 ret, ... := XXFunc(...)
 assert.Equal(t, ret, ...)
}

go test -v  wechat_test.go wechat.go 

go test -v wechat_test.go -test.run TestRefreshAccessToken

package main 
import (
 "fmt"
 "testing"
)
 
func TestFmt1(t *testing.T) {//1 方法必须传入testing.T 2 方法名必须是以Test开头，驼峰命名
 fmt.Println("test1")
}
func TestFmt2(t *testing.T) {
 fmt.Println("test2")
}
