tests: add regression tests for xtables-translate
This test suite is intended to detect regressions in the translation
infrastructure. The script checks if ip[6]tables-translate produces the
expected output, otherwise it prints the wrong translation and the
expected one.
** Arguments
--all # Show also passed tests
[test] # Run only the specified test file
** Test files structure
Test files are located under extensions directory. Every file contains
tests about specific extension translations. A test file name must end
with ".txlate".
Inside the files, every single test is defined by two consecutive lines:
ip[6]tables-translate command and expected result. One blank line is left
between tests by convention.
e.g.
$ cat extensions/libxt_cpu.txlate
iptables-translate -A INPUT -p tcp --dport 80 -m cpu --cpu 0 -j ACCEPT
nft add rule ip filter INPUT tcp dport 80 cpu 0 counter accept
iptables-translate -A INPUT -p tcp --dport 80 -m cpu ! --cpu 1 -j ACCEPT
nft add rule ip filter INPUT tcp dport 80 cpu != 1 counter accept
