This is built on top of the testplan.common.utils.sockets.fix.server.Server class, which provides equivalent functionality and may be used outside of MultiTest.

NOTE: FixServer requires select.poll(), which is not implemented on all operating systems - typically it is available on POSIX systems but not on Windows.

Parameters:

• name (str) – Name of FixServer.

• msgclass (type) – Type used to send and receive FIX messages.

• codec (a Codec instance) – A Codec to use to encode and decode FIX messages.

• host (str) – Host name to bind to. Default: ‘localhost’

• port (int) – Port number to bind to. Default: 0 (Random port)

• version (Optional[TLSConfig]) – FIX version, defaults to “FIX.4.2”. This string is used as the contents of tag 8 (BeginString).

• tls_config – If provided the connection will be encrypted

Also inherits all Driver options.

receive(conn_name=(None, None), timeout=60)

Receive a FIX message from the given connection.

Parameters:

• conn_name (tuple of str and str) – Connection name (sender and target ids) to receive message from.

• timeout (int or NoneType) –

  timeout in seconds or None

  • Specifying None as timeout will turn receive into a non-blocking call. In such case, if no message is immediately available, None is returned and no exception is raised.

  • Specifying a numeric value will make receive a blocking call. If no message is received within the timeframe, a TimeoutException is raised.

Returns:

received FixMessage object
