我使用大猩猩Web套接字框架,并使用以下客户端在本地运行Web套接字并对其进行调试
https://github.com/gorilla/websocket
ws = new WebSocket("ws://localhost:8080/mypath") ws.onmessage = function(ev) { console.log(ev.data) } ws.send("hello")
当我在chrome控制台中使用它时此方法有效,但是我的问题是是否有一种方法可以进行一些单元测试并避免使用chrome控制台?
使用net / http / httptest软件包创建一个测试服务器。使用Gorilla客户端连接到该服务器。读取和写入消息以测试连接。
package main import ( "net/http" "net/http/httptest" "strings" "testing" "github.com/gorilla/websocket" ) var upgrader = websocket.Upgrader{} func echo(w http.ResponseWriter, r *http.Request) { c, err := upgrader.Upgrade(w, r, nil) if err != nil { return } defer c.Close() for { mt, message, err := c.ReadMessage() if err != nil { break } err = c.WriteMessage(mt, message) if err != nil { break } } } func TestExample(t *testing.T) { // Create test server with the echo handler. s := httptest.NewServer(http.HandlerFunc(echo)) defer s.Close() // Convert http://127.0.0.1 to ws://127.0.0. u := "ws" + strings.TrimPrefix(s.URL, "http") // Connect to the server ws, _, err := websocket.DefaultDialer.Dial(u, nil) if err != nil { t.Fatalf("%v", err) } defer ws.Close() // Send message to server, read response and check to see if it's what we expect. for i := 0; i < 10; i++ { if err := ws.WriteMessage(websocket.TextMessage, []byte("hello")); err != nil { t.Fatalf("%v", err) } _, p, err := ws.ReadMessage() if err != nil { t.Fatalf("%v", err) } if string(p) != "hello" { t.Fatalf("bad message") } } }
