Fiddler 4 Classic. WebSocket test Generator

1. Register Custom Hotkey Alt+G.cs

// https://www.telerik.com/blogs/what-s-new-in-fiddler-2-4-4-5

public static void Main() {
  // ...
  FiddlerApplication.UI   
    .RegisterCustomHotkey(
      HotkeyModifiers.Alt,    
      Keys.G, 
      "Generate"
    );
  // ...
}

2. Handle command Generate.cs

public static bool OnExecAction(string[] sParams) {
  // ...  
  case "Generate":    
    doGenerateCode();    
    return true;
  // ...
}

3. Implement command Generate.cs

public static void doGenerateCode() {  
  var arrS = FiddlerApplication.UI.GetSelectedSessions();  
  for (int x = 0; x < arrS.Length; x++) {   
    var session = arrS[x];   
    if (session.isFlagSet(SessionFlags.IsWebSocketTunnel)) {    
      var headers = session.oRequest.headers;    
      if(    headers.Get("wsFrom")=="Client" 
          && headers.Get("wsFrameType")=="Text"
        //&& ...
        ) {
        // ... generation 
        // file.append("ws.send(\"" + headers.Get("wsPayload") + "\");" );
        // ... generation 
      } 
    } 
  } 
}
