How to use or fix problem when I test unit-testing below trpc-go

Question

Additional Information

My unit-testing code

package service

import (
	"context"
	"flag"
	"testing"

	pb "code.teamsun.com/global_pb/intelligent_assistance.git/intelligent_assistance"
	"teamsun.com/intelligent_assistance/intelligent_assistance/internal/config"
	"teamsun.com/intelligent_assistance/intelligent_assistance/internal/dao"
	"teamsun.com/intelligent_assistance/intelligent_assistance/internal/model"
	"trpc.group/trpc-go/trpc-go"

	_ "trpc.group/trpc-go/trpc-filter/debuglog"
	_ "trpc.group/trpc-go/trpc-filter/recovery"
)

func init() {
	flag.String("config", "../../config/trpc_go.yaml", "")
	flag.String("test.run", "", "")
	s := trpc.NewServer()
	config.InitServerConfig()
	dao.New()
	pb.RegisterIntelligentAssistanceService(s.Service("intelligent_assistance.trpc"),
		&IntelligentAssistanceImpl{})
	go s.Serve()

	print("init server config success")
}

func TestEndCall(t *testing.T) {
	endCall(context.Background(), "1009", &model.CallInfo{
		Staff:        "staff",
		EnterpriseId: "1658884c2f644cdfbb647cfdb1689041",
	})
}

got:

init server config success/root/code/intelligent_assistance/internal/service/__debug_bin1147665774 flag redefined: test.run
panic: /root/code/intelligent_assistance/internal/service/__debug_bin1147665774 flag redefined: test.run

	/usr/local/go/src/flag/flag.go:899 +0x65
testing.Init()
	/usr/local/go/src/testing/testing.go:428 +0x28b

When I delete extra code. Like this:

func init() {
	trpc.NewServer()
	config.InitServerConfig()
	dao.New()

	print("init server config success")
}

got:

2024/07/01 16:23:10 maxprocs: Leaving GOMAXPROCS=4: CPU quota undefined
flag provided but not defined: -test.run
Usage of /root/code/intelligent_assistance/internal/service/__debug_bin862289461:
  -conf string
    	server config path (default "./trpc_go.yaml")

Or how to use unit tests below trpc-go?
Thank you in advance for your help
