)


var T = New("this is test")

func TestWrap(t *testing.T) {
    var e error
    e = errors.New("Error One")
    e = T.Wrap(e)
    e = e.(*Error).Wrap(e)
    e = Wrap(e)
    e = Wrap(e)
    e = Wrap(e)
    fmt.Printf("%+v\n", e)
    fmt.Printf("%s\n", e.Error())
    
    e2 := New("Error Two")
    e = e.(*Error).Wrap(e2)
    e = Wrap(e)
    e = Wrap(e)
    fmt.Printf("%+v", e)
