httptestはGoでhttp関係のテストをすることに使用します。

godoc

• NewServer(handler http.Handler)は*Serverを返す

• Server.URLはipとportだけのBase URL

Example

hrqのテストの例

package hrq

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

func TestGetRequest(t *testing.T) {
	server := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		v1 := r.URL.Query().Get("abc")
		if v1 != "def" {
			t.Errorf("v1 is wrong in TestGetRequest(). v1 is %v", v1)
		}
		v2 := r.URL.Query().Get("hij")
		if v2 != "klm" {
			t.Errorf("v2 is wrong in TestGetRequest(). v2 is %v", v2)
		}
		c1, _ := r.Cookie("c1")
		if c1.Value != "v1" {
			t.Errorf("c1 is wrong in TestGetRequest(). c1 is %v", c1)
		}
		c2, _ := r.Cookie("c2")
