##### 怎样编写 Gin 的测试用例 HTTP 测试首选 `net/http/httptest` 包。 {{<highlight go>}} package main func setupRouter() *gin.Engine { r := gin.Default() r.GET("/ping", func(c *gin.Context) { c.String(200, "pong") }) return r } func main() { r := setupRouter() r.Run(":8080") } {{</highlight>}} 上面这段代码的测试用例： ```go package main import ( "net/http" "net/http/httptest" "testing" "github.com/stretchr/testify/assert" ) func TestPingRoute(t *testing.T) { router := setupRouter() w := httptest.NewRecorder() req, _ := http.NewRequest("GET", "/ping", nil) router.ServeHTTP(w, req) assert.Equal(t, 200, w.Code) assert.Equal(t, "pong", w.Body.String()) } ```
