Testing 测试

怎样编写 Gin 的测试用例

HTTP 测试首选 net/http/httptest 包。

package main

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")
}

上面这段代码的测试用例：

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())
}
