Create mocked http session with scapy python

Question

How can i create a HTTP session and save the packets of it? i have got this code:

import logging logging.getLogger("scapy.runtime").setLevel(logging.ERROR)

from scapy.all import *

get='GET / HTTP/1.0\n\n'

ip=IP(dst="www.google.com")

port=RandNum(1024,65535)

SYN=ip/TCP(sport=port, dport=80, flags="S", seq=42)

SYNACK=sr1(SYN)

ACK=ip/TCP(sport=SYNACK.dport, dport=80, flags="A", seq=SYNACK.ack, ack=SYNACK.seq + 1) / get

reply,error=sr(ACK)

but in my code i don't want to send any packets just to get the answer(simulate the situation of the sending functions of SYNACK=sr1(SYN) and reply,error=sr(ACK) without really using them).. i want to simulate the session between two ips(with their ports) and with the payload and then save everything as packets as cap file.. how can i do this?

The jargon you're looking for is 'mocking'. Later versions of python unit testing have unittest.mock and there are also external libraries available that can pretend to be external sources like files, databases and websites that allow you to test your code.
