when I run the minimal program below it errors about NOT knowing -data
flag:
go test -v -args -data=x
flag provided but not defined: -data
Usage of
/tmp/go-build454762170/github.com/phcurtis/flagexp/_test/flagexp.test:
-test.bench regexp .... blah blah,
if you change nfs=false ... and then it uses flag.Parse etc ... code runs
without issue
but I want to handle error cases in other code I'm working and use the
flag.NewFlagSet with go test ...
note the below code in either case works with go run but not with go test.
package main
import (
"flag"
"fmt"
"os"
"testing"
)
var data string
var test func(t *testing.T)
var datainit = "defValue"
var nfs = true
func init() {
if nfs {
flag3 := flag.NewFlagSet("nfs", flag.ContinueOnError)
flag3.StringVar(&data, "data", datainit, "data")
test = func(t *testing.T) {
fmt.Println("TP1")
err := flag3.Parse(os.Args)
fmt.Printf("data:%v err:%v\n", data, err)
}
return
}
flag.StringVar(&data, "data", datainit, "data")
test = func(t *testing.T) {
fmt.Println("TP2")
flag.Parse()
fmt.Printf("data:%v\n", data)
}
}
func Test_code(t *testing.T) {
test(t)
}

heres full output when nfs=true
