///     CompressionOptions compression: CompressionOptions.compressionDefault

/// Create a new WebSocket connection. The URL supplied in url must use the
/// scheme ws or wss.
/// The protocols argument is specifying the subprotocols the client is willing
/// to speak.
/// The headers argument is specifying additional HTTP headers for setting up
/// the connection. This would typically be the Origin header and potentially
/// cookies. The keys of the map are the header fields and the values are either
/// String or List.
/// If headers is provided, there are a number of headers which are controlled by
/// the WebSocket connection process. These headers are:
/// - connection
/// - sec-websocket-key
/// - sec-websocket-protocol
/// - sec-websocket-version
/// - upgrade
/// If any of these are passed in the headers map they will be ignored.
/// If the url contains user information this will be passed as basic
/// authentication when setting up the connection.
/// @description Checks that the static method WebSocket.connect creates a new
/// Future that will complete with WebSocket. Tests methods and properties of
/// created instance (error processing)
