From 31611cea8f0f45f0b803b010be47a37792ba58a8 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 19 Apr 2024 19:52:36 -0700 Subject: selftests: drv-net: add a TCP ping test case (and useful helpers) More complex tests often have to spawn a background process, like a server which will respond to requests or tcpdump. Add support for creating such processes using the with keyword: with bkg("my-daemon", ..): # my-daemon is alive in this block My initial thought was to add this support to cmd() directly but it runs the command in the constructor, so by the time we __enter__ it's too late to make sure we used "background=True". Second useful helper transplanted from net_helper.sh is wait_port_listen(). The test itself uses socat, which insists on v6 addresses being wrapped in [], it's not the only command which requires this format, so add the wrapped address to env. The hope is to save test code from checking if address is v6.
