go ：gin 編寫測試代碼

背景：
本文實驗 gin框架下 測試代碼的編寫
功能代碼

package main

import (
	"github.com/gin-gonic/gin"
)

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")
}

測試代碼

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())
}

這裏需要注意的是測試代碼文件的命名 必須以 *_test.go 格式 ， 我當前的是 main_test.go
執行測試代碼
go test -v main_test.go
