Constructor Details

#initialize ⇒ Socket

Create a new test socket. This will also instantiate a new Net::SSH::Test::Script and seed it with the necessary events to power the initialization of the connection.

def port
  @port
end

#script ⇒ Object (readonly)

The Net::SSH::Test::Script object in use by this socket. This is the canonical script instance that should be used for any test depending on this socket instance.

Instance Method Details

#getpeername ⇒ Object

Returns a sockaddr struct for the port and host that were used when the socket was instantiated.

# File 'lib/net/ssh/test/socket.rb', line 49

def getpeername
  ::Socket.sockaddr_in(port, host)
end

#open(host, port) ⇒ Object

Allows the socket to also mimic a socket factory, simply returning self.

def open(host, port)
  @host, @port = host, port
  self
end

#recv(n) ⇒ Object

Alias to #read, but never returns nil (returns an empty string instead).

# File 'lib/net/ssh/test/socket.rb', line 54

def recv(n)
  read(n) || ""
end

#write(data) ⇒ Object

This doesn’t actually do anything, since we don’t really care what gets written.
