The net/http/httptest package is preferable way for HTTP testing.

    1. package main
    3. func setupRouter() *gin.Engine {
    4.     r := gin.Default()
    5.     r.GET("/ping", func(c *gin.Context) {
    6.         c.String(200, "pong")
    7.     })
    8.     return r
    9. }
    11. func main() {
    12.     r := setupRouter()
    13.     r.Run(":8080")
    14. }
    1. package main
    3. import (
    4.     "net/http"
    5.     "net/http/httptest"
    6.     "testing"
    8.     "github.com/stretchr/testify/assert"
    9. )
    11. func TestPingRoute(t *testing.T) {
    12.     router := setupRouter()
    14.     w := httptest.NewRecorder()
    15.     req, _ := http.NewRequest("GET", "/ping", nil)
    16.     router.ServeHTTP(w, req)
    18.     assert.Equal(t, 200, w.Code)
    19.     assert.Equal(t, "pong", w.Body.String())
    20. }
