vs code debuging go tests not passing flags-CodePudding

I`m trying to config a debugger on vs-code to some tests in go. I have to pass some flags to it, but it's not working well.

main.go

package main

import (
    "flag"
    "fmt"
)

func DoTheThing() {
    flag1Ptr := flag.Bool("flag1", false, "flag1 is a flag")
    flag.Parse()
    fmt.Println(*flag1Ptr)
    fmt.Println("Hello, world")
}

func main() {
    DoTheThing()
}

main_test.go

package main

import "testing"

func TestDoTheThing(t *testing.T) {
    DoTheThing()
}

launch.json

{
    "name": "Launch app",
    "type": "go",
    "request": "launch",
    "mode": "auto",
    "program": "${workspaceFolder}",
    "args": [
        "-flag1"
    ]
},
{
    "name": "Run Tests",
    "type": "go",
    "request": "launch",
    "mode": "test",
    "program": "${workspaceFolder}",
    "args": [
        "--", "-flag1"
    ]
}

if I run it with Launch app config it pass the value in the right way, but using the test one it do not set the parameter

output using Launch app config

true
Hello, world

output using Run Tests config

false
Hello, world
