Pcap_check_zero_window.py what is this file checking?

I am failing this unit test. Please let me know which milestone the file is related to.

Hey @17ucc018 Zero Window is something to investigate. TCP Zero Window is when the Window size in a machine remains at zero for a specified amount of time. This means that a client is not able to receive further information at the moment, and the TCP transmission is halted until it can process the information in its receive buffer.

and you can see this into tcp_issue1.pcap file by opening into the wireshark and also you can apply filter to check this out.

it is related zero_window_details file
