You could actually make a stress test inside a main_test.go with a
benchmark for example, run that locally and see.
It works over here btw.
package main_test
import (
"net/http"
"net/http/httptest"
"testing"
"github.com/gorilla/mux"
"github.com/stretchr/testify/assert"
)
func pingServer(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("pong"))
}
func Router() *mux.Router {
router := mux.NewRouter()
router.HandleFunc("/ping", pingServer).Methods("GET")
return router
}
func Test_Ping(t *testing.T) {
r, _ := http.NewRequest("GET", "/ping", nil)
w := httptest.NewRecorder()
Router().ServeHTTP(w, r)
assert.Equal(t, 200, w.Code, "OK response is expected")
}
func Benchmark_Ping(b *testing.B) {
r, _ := http.NewRequest("GET", "/ping", nil)
w := httptest.NewRecorder()
b.ResetTimer()
for i := 0; i < b.N; i++ { // use b.N for looping
Router().ServeHTTP(w, r)
assert.Equal(b, 200, w.Code, "OK response is expected")
}
}
