ARTS-S golang函数作为参数传递

函数作为参数传递在单元测试的时候非常有用，看下面的例子。

package main

import "fmt"

func output(f func(string, string, string), fileName string,
	got string, right string) {
	f(fileName, got, right)
}

func funcA(fileName, got, right string) {
	if got == right {
		fmt.Println("right")
	} else {
		fmt.Println("wrong")
	}
}

func funcB(fileName, got, right string) {
	if got == right {
		fmt.Println("right")
	} else {
		fmt.Println("wrong")
	}
}

func main() {
	output(funcA, "aaa", "c", "bbb")
	output(funcB, "aaa", "bbb", "bbb")
}
