测试

简单api测试示例

HTTP 测试首选 net/http/httptest 包。

main.go 文件

package main

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

func pingHandler(c *gin.Context) {
	c.String(200, "pong")
}

func setupRouter() *gin.Engine {
	router := gin.Default()
	router.GET("/ping", pingHandler)

	return router
}

func main() {
	r := setupRouter()

	err := r.Run("127.0.0.1:8000")
	if err != nil {
		fmt.Println(err)
		return
	}
}

main_test.go 文件

package main

import (
	"github.com/stretchr/testify/assert"
	"net/http"
	"net/http/httptest"
	"testing"
)

func TestPing(t *testing.T) {
	r := setupRouter()
	w := httptest.NewRecorder()
	req, _ := http.NewRequest("GET", "/ping", nil)
	r.ServeHTTP(w, req)

	assert.Equal(t, 200, w.Code)
	assert.Equal(t, "pong", w.Body.String())
}

处理依赖关系

go mod tidy

执行单元测试

go test -v .
