HTTP Integration Tests

HTTP integratsion testlari

Bitta handler'ni emas, butun router (ServeMux)ni — turli yo'llar to'g'ri handler'larga yo'naltirilishini — birgalikda sinash "integratsion test" deyiladi. Jadval asosidagi test bilan bir nechta yo'lni bitta testda tekshirish mumkin.

example.go

package main

import (
	"net/http"
	"net/http/httptest"
	"testing"
)

func setupMux() *http.ServeMux {
	mux := http.NewServeMux()
	mux.HandleFunc("GET /status", func(w http.ResponseWriter, r *http.Request) {
		w.WriteHeader(http.StatusOK)
		w.Write([]byte("ishlayapti"))
	})
	mux.HandleFunc("GET /missing", func(w http.ResponseWriter, r *http.Request) {
		w.WriteHeader(http.StatusNotFound)
	})
	return mux
}

func TestRoutes(t *testing.T) {
	mux := setupMux()

	tests := []struct {
		name string
		path string
		want int
	}{
		{"mavjud yo'l", "/status", http.StatusOK},
		{"mavjud bo'lmagan yo'l", "/missing", http.StatusNotFound},
	}

	for _, tc := range tests {
		t.Run(tc.name, func(t *testing.T) {
			req := httptest.NewRequest("GET", tc.path, nil)
			rec := httptest.NewRecorder()
			mux.ServeHTTP(rec, req)
			if rec.Code != tc.want {
				t.Errorf("status = %d, kutilgan %d", rec.Code, tc.want)
			}
		})
	}
}

setupMux() — router'ni bir joyda quradi, uni ham asosiy dasturda, ham testda ishlatish mumkin. mux.ServeHTTP(rec, req) esa haqiqiy so'rovni router orqali o'tkazadi — xuddi haqiqiy server ichida bo'lgandek, faqat tarmoqsiz. Bu naqsh butun API'ning "yo'llar to'g'ri ulanganmi" degan savoliga javob beradi.

>_ Exercise

Ikkita yo'lli router'ni integratsion test bilan tekshiring.

•"/ok" 200, "/forbidden" 403 qaytaradigan router yozing
•jadval asosida ikkalasini ham t.Run bilan tekshiring

Key Takeaway

Key Takeaway:

Integratsion testlar butun router'ning (ko'plab yo'llarning birgalikda) to'g'ri ishlashini tekshiradi — alohida handler testlaridan bir qadam kattaroq ishonch beradi.
