Question

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：

localhost:8080

所以我可能会点击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>"]}'上运行的应用程序：

http://www.coolsongssite.api

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

我应该重写client.Do(request)处理程序，以便隔离incomingRequestToOutgoingRequest中发生的事情吗？

我们赞赏任何正确方向的帮助/建议/要点。

我可以在这里测试package main import ( "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
...

测试Go（Golang）API传出请求而不实际触及第三方API
