如何从Go中的字符串方法名称调用另一个包的方法

Question

Suppose I have two package like

-a

-b

a have some methods like this

 func TestOne() { //something }
 func TestTwo() { //something }

I need to call package a's methods from package b but by only string method name. Like i get the string "TestOne" and calls for the method TestOne(). How can i get that done.

Edit : I have Read about reflect. but reflect needs an struct and functions be a member of that struct. What if My functions are not member of a struct? just plain methods in a package. and the calling methods and called methods are in different package. Then?

NB. There could be some methods that have parameters as well.

You can try to use reflect in go. This link may be help you https://golang.org/pkg/reflect/ and http://mikespook.com/2012/07/function-call-by-name-in-golang/

func foo() {
    // bla...bla...bla...
}
func bar(a, b, c int) {
    // bla...bla...bla...
}
funcs := map[string]interface{}{"foo":foo, "bar":bar}
