[PATCH v3] tests: tests for libnftables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Makefile and tests files for libnftables.

In this patch, I create a initial object 'a' and I set a testing values. Then,
I convert this object in a Netlink message.

>From this Netlink message, I parse that (through nft_table_nlmsg_parse
function) in 'b' objetc.

Thus, we make sure that object transformations are correct.
---

v2: fix writing erorres in messages that I unintentionally added in v1 that
were spotted by Phil Oester.

Fix a multiline comment error. The nft-ruleset-test is not included
in this patch, also, I delete it in the tests/test-script.sh. Those errors were 
spotted by Arturo Borrero.

v3: I fix some initialization errors, I remove unnecessary comments and I
include a copyright notice. Those errors were spotted by Artulo Borreo.
