# 79-libnftnl.test -- libnftnl 1.2.6, the low-level nftables Netlink library.
#
# libnftnl ships no program of its own, so the only coverage that means anything is
# upstream's own tests/ tree -- the same 32 programs ptest-runner drives. Each one
# builds an nftables netlink message from a struct, parses the buffer back into a
# second struct, and compares it field by field, printing OK only when every field
# survived the round trip. They open no socket and read no /proc, so none of this
# needs nftables kernel support; what is under test is the serialisation and parsing
# code, which is the whole of what the library does.
