测试Go(Golang)API传出请求而不实际触及第三方API

概述我正在开发一个Go API,它在内部后端和几个第三方API之间进行转换.我试图了解如何在不实际使用外部API的情况下测试其功能. 例如,这是一个处理传入请求以制作新歌曲的服务器,并将请求发送给第三方API： package mainimport ( "bytes" "encoding/json" "fmt" "net/http" 我正在开发一个Go API,它在内部后端和几个第三方API之间进行转换.我试图了解如何在不实际使用外部API的情况下测试其功能.

例如,这是一个处理传入请求以制作新歌曲的服务器,并将请求发送给第三方API：

package mainimport (        "bytes"        "enCoding/Json"        "fmt"        "net/http")var ThirdPartyAPI = "http://www.coolsongssite.API"type IncomingRequest struct {        username string         `Json:"username"`        password string         `Json:"password"`        songs    []IncomingSong `Json:"songs"`}type OutgoingRequest struct {        username string         `Json:"username"`        password string         `Json:"password"`        songs    []OutgoingSong `Json:"songs"`}type IncomingSong struct {        artist string `Json:"artist"`        album  string `Json:"album"`        Title  string `Json:"Title"`}type OutgoingSong struct {        musician string `Json:"musician"`        record   string `Json:"record"`        name     string `Json:"name"`}func main() {        http.HandleFunc("/songs/create",createSong)        http.ListenAndServe(":8080",nil)}func createSong(rw http.ResponseWriter,req *http.Request) {         decoder := Json.NewDecoder(req.Body)         var incomingRequest IncomingRequest         decoder.Decode(&incomingRequest)         outgoingRequest := incomingRequestToOutgoingRequest(incomingRequest)         r,_ := Json.Marshal(outgoingRequest)         request,_ := http.NewRequest("POST",ThirdPartyAPI,bytes.NewBuffer(r))         request.header.Set("Content-Type","application/Json")         clIEnt := http.ClIEnt{}         response,_ := clIEnt.Do(request)         fmt.Fprintln(rw,response)}func incomingRequestToOutgoingRequest(inc IncomingRequest) OutgoingRequest {        outgoingRequest := OutgoingRequest{                username: inc.username,password: inc.password,}        for _,s := range inc.songs {                outgoingRequest.songs = append(                        outgoingRequest.songs,OutgoingSong{                                musician: s.artist,record:   s.album,name:     s.Title,},)        }        return outgoingRequest}

所以我可能会点击在localhost：8080上运行的应用程序：

curl -X POST http://localhost:8080/songs/new --data \'{"username": "<my-username>","password": "<my-password>","songs": \["artist": "<song-artist>","Title": "<song-Title>","album": "<song-album>"]}'

我的问题是：
如何编写测试来测试发出的请求(在本例中为http：//www.coolsongssite.API)是否正确,而不实际发送？

我应该重写createSong处理程序,以便我可以隔离clIEnt.Do(请求)中发生的事情吗？

任何有关正确方向的帮助/建议/要点都会受到赞赏.

在这里我可以像这样测试incomingRequestToOutgoingRequest：

package mainimport (        "testing")func TestincomingRequestToOutgoingRequest(t *testing.T) {        incomingRequest := IncomingRequest{                username: "myuser",password: "mypassword",}        var songs []IncomingSong        songs = append(                songs,IncomingSong{                artist: "White Rabbits",album:  "Milk Famous",Title:  "I'm Not Me",)        outgoingRequest := incomingRequestToOutgoingRequest(incomingRequest)        if outgoingRequest.songs[0].musician != "White Rabbits" {                t.Error("Expected musican name to be 'White Rabbits'. Got: ",outgoingRequest.songs[0].musician)        }}

您可以像这样使用net / http / httptest.NewServer：

ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter,r *http.Request) {    w.Write([]byte(`desired response here`))}))defer ts.Close()ThirdPartyAPI = ts.URL...your test here
