我编写了一个将数据保存到redis数据库服务器的函数。挑战在于我想测试这些功能,而不知道如何测试它。
我只是以某种方式开始
功能
package sessrage
/*
* Save data into redis database. In the common case,
* the data will be only valid during a request. Use
* hash datatype in redis.
*/
import (
"../context"
"github.com/garyburd/redigo/redis"
"net/http"
)
const (
protocol string = "tcp"
port string = ":6379"
)
func connectAndCloseRedis(connectCall func(con redis.Conn)) {
c, err := redis.Dial("tcp", ":6379")
defer c.Close()
if err != nil {
panic(err.Error())
}
connectCall(c)
}
func PostSessionData(r *http.Request, key, value string) {
go connectAndCloseRedis(func(con redis.Conn) {
sessionId := context.Get(r, context.JwtId).(string)
con.Do("HMSET", sessionId, key, value)
})
}
func GetSessionData(r *http.Request, key string) interface{} {
var result interface{}
sessionId := context.Get(r, context.JwtId).(string)
reply, _ := redis.Values(c.Do("HMGET", sessionId, key))
redis.Scan(reply, &result)
return result
}
和测试文件
package sessrage
import (
//"fmt"
"../context"
. "github.com/smartystreets/goconvey/convey"
"github.com/stretchr/testify/assert"
"net/http"
"net/http/httptest"
"testing"
"time"
)
var server *httptest.Server
var glrw http.ResponseWriter
var glr *http.Request
func init() {
server = httptest.NewServer(http.HandlerFunc(func(rw http.ResponseWriter, r *http.Request) {
glrw = rw
glr = r
context.Set(glr, context.JwtId, "TestId")
}))
}
func TestPostAndGetSession(t *testing.T) {
Convey("POST and GET data on redis.", t, func() {
PostSessionData(glr, "key1", "value1")
time.Sleep(time.Second * 10)
v := GetSessionData(glr, "key1")
assert.Equal(t, "value1", v)
})
}
当我尝试运行测试时,我已经
了an't load package: ......./sessrage.go:10:2: local import "../context" in non-local package
,上下文包看起来像
package context
import (
"github.com/gorilla/context"
"net/http"
)
type contextKey int
const (
LanguageId contextKey = iota
JwtId
)
func Get(r *http.Request, key interface{}) interface{} {
return context.Get(r, key)
}
func Set(r *http.Request, key, val interface{}) {
context.Set(r, key, val)
}
我错了什么?
这是我第一次和http一起测试代码。这似乎很难测试。
答案 0 :(得分:1)
有一些问题:
如果调用链中的多路复用器或更高级别的内容在goroutine之前清除Gorilla上下文,则对PostSessionData匿名函数中的sessionId:= context.Get(r,context.JwtId)。(string)的调用可能会失败运行。这样做:
func PostSessionData(r *http.Request, key, value string) {
c := pool.Get()
defer c.Close()
sessionId := context.Get(r, context.JwtId).(string)
if err := c.Do("HMSET", sessionId, key, value); err != nil {
// handle error
}
}
