[raydac]

what is the absolute path to folder with tests? and what is the OS?

[bogdanpredescu]

D:\workspace\mymavenparentproject\myproject\src\program
in case you suspect the path's length, the actual project names are shorter.

Windows 7

It's a very basic project following the example available here on the site (math.go)

In the "program" folder there are two files:

program. go

and

program_test.go which has this content (it actually doesn't test anything from the other file) :

package main

import (
"testing"
)

func TestHelloWorld(t *testing.T) {
str := HelloWorld("xxx")
if str != "xxx" {
t.Fail()
}

}
