func main() {
	// Start a server
	srv, address := startHttpServer()

	// Wait starting of server
	<-wait.ByAddress(address)

	// Testing
	resp, err := http.Get(address)
	if err != nil {
		fmt.Println("RESPONSE")
		panic(err)
	}
	fmt.Println("Server is run...")
	_ = resp.Body.Close()
	if err := srv.Shutdown(context.Background()); err != nil {

)

func startHttpServer() (*http.Server, string) {
	port := 8090
	address := fmt.Sprintf("http://127.0.0.1:%d", port)

	srv := &http.Server{Addr: fmt.Sprintf(":%d", port)}

	go func() {
		time.Sleep(5 * time.Millisecond)
		_ = srv.ListenAndServe()
	}()

	return srv, address
}

func main() {
	// Start a server
	srv, address := startHttpServer()

	// Wait starting of server
	<-wait.ByAddress(address)

	// Testing
	resp, err := http.Get(address)
	if err != nil {
		fmt.Println("RESPONSE")
		panic(err)
	}
	fmt.Println("Server is run...")
	_ = resp.Body.Close()
	if err := srv.Shutdown(context.Background()); err != nil {
		panic(err)
	}
