Add zombienet integration tests

[wirednkod]

This PR replaces the one that @pepoviola opened before - mainly for keeping the history clean

Hi @wirednkod, I updated the version of zombienet and the feature file to just run the 0002 test without matching the output.

Thanks!

I suppose that the numbers, such as 0001 and 0002 are a convention so that we easily know which file belongs to which test. However we call 0002-getHeaders from 0001-..., so I'd like to understand

Hi @tomaka/@wirednkod , I will clean the naming here and try to remove the sleep.
Thanks!

We seem to mix require and import here. Maybe decide on which one?

[tomaka]

Maybe name the file 0002-checkSync.js or something, and not placeholder?

[tomaka]

Would be good to merge for me after my two comments (provided it works obviously)

Hi @tomaka, can you give me some hints on this error:

We launch a relay-chain with 2 validator and a parachain with 2 collator:

• The parachain is producing blocks ok
• The relay-chain spec have 2 bootnodes
• The parachain spec have 1 bootnode.

Thanks!!

As always, I need debug logs.
Debug logs really should be always enabled by default for the ZombieNet tests.

[tomaka]

It seems that smoldot can't connect to the peer-to-peer network of the parachain, but also doesn't even try to connect. Are you sure that there are bootnodes in the parachain spec?

[pepoviola]

Thanks for the feedback @tomaka

I checked the logs and there is a pending connection to the parachain bootnode.

[tomaka]

Sorry, didn't realize that the search in GitHub's logs viewer stops after 100 lines without even telling you. 😮‍💨

[tomaka]

The problem is that you're passing --listen-addr on the relay chain side of the node, and not on its parachain side.
In other words /ip4/127.0.0.1/tcp/37227/ws/p2p/12D3KooWLj7rSyPHpVp4zBf8S9nu7LM5eep8iFpWT8eMKgrrNF29 would be appropriate for a relay chain bootnode but not a parachain bootnode.
