web单元测试

1.测试项目初建

单元测试是项目不能缺少的模块，也是保障项目可以正常运行的重要依赖。下面就对　Gin 进行单元测试。
为了方便单元测试，我们首先要对我们的项目进行一下抽取，新建立一个文件夹叫做 initRouter

建立 go 文件 initRouter.go
package initRouter

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

func SetupRouter() *gin.Engine {
	router := gin.Default()
	// 添加 Get 请求路路由
	router.GET("/", func(context *gin.Context) {
		context.String(http.StatusOK, "hello gin")
	})
	return router
}
增加main.go
package main

import (
	"GinHello/initRouter"
)

func main() {
	router := initRouter.SetupRouter()
	_ = router.Run()
}
完成了项目测试的初步建立

2.创建单元测试

建立 test 目录, golang 的单元测试都是以 _test 结尾，建立 index_test.go 文件

package test

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

func TestIndexGetRouter(t *testing.T) {
	router := initRouter.SetupRouter()
	w := httptest.NewRecorder()
	req, _ := http.NewRequest(http.MethodGet, "/", nil)
	router.ServeHTTP(w, req)
	assert.Equal(t, http.StatusOK, w.Code)
	assert.Equal(t, "hello gin", w.Body.String())
}

通过 assert 进行断言，来判断返回状态码和返回值是否与代码中的值一致。
此时的项目目录为：

GinHello
|
|-initRouter
| |-initRouter.go
|
|-test
| |-index_test.go
|
|-main.go
|-go.mod
|-go.sum

3.运行单元测试

运行单元测试，控制台打印出单元测试结果。

PASS: TestIndexGetRouter (0.05s) PASS
