I would like to Unit Test my NFT code. Is there a way to mock interfaces of Conn, Set, Rule and expressions? I.e. I want to apply some rules to the chain and print out results so that it could be tested against expected rules.

In current implementation I encounter problem that UT must be executed using sudo as rules are applied directly to NFT: https://github.com/google/nftables/blob/main/nftables_test.go
