Is it possible to get the current root of package structure as a string in golang test?

You can also use my method without C:

package mypackage

import (
    "path/filepath"
    "runtime"
    "fmt"
)

var (
    _, b, _, _ = runtime.Caller(0)
    basepath   = filepath.Dir(b)
)

func PrintMyPath() {
    fmt.Println(basepath)
}
