Integration between nimbus-eth1 and Ethereum Hive test environment

This is a short manual to help you quickly setup and run Hive. For more detailed information please read the hive documentation.

Prerequisities

A Linux machine. Trust me, it does not work on Windows or MacOS.
Or Linux inside a VM (e.g. VirtualBox) on Windows or MacOS.
Docker installed and working in your Linux.
Go compiler installed in your Linux.
Go must be version 1.16 or later.

Practicalities

Practically, if using an Ubuntu Linux and you want to use the version of Go shipped with Ubuntu, you will need Ubuntu 21.04 or later. It's enough to run apt-get install golang.

If using Ubuntu 20.04 LTS (likely because it's the long-term stable version), the shipped Go isn't recent enough, and there will be build errors. You can either install a non-Ubuntu packaged version of Go (maybe from golang.org, or use a more recent Ubuntu.

If you want to run Hive in a Linux container, you will need Docker to work in the container because Hive calls Docker (a lot!). This is sometimes called "Docker in Docker". Inside LXD containers, Docker doesn't work by default, but usually this is remedied by setting the container flag lxc config set $CONTAINER_NAME security.nesting true, which takes effect immediately.

Building hive

First you will need a working Go installation, Go 1.16 or later. Then:

git clone https://github.com/ethereum/hive
cd ./hive
go build .

How to run hive

First copy the nimbus-eth1/hive_intgration/nimbus folder (from this repo) into the hive/clients folder (in the hive repo).

Then run this command:

./hive --sim <simulation> --client <client(s) you want to test against>

Examples:

./hive --sim ethereum/consensus --client nimbus

./hive --sim devp2p/discv4 --client go-ethereum,openethereum,nimbus

Available test suites / simulators

devp2p/eth
devp2p/discv4
ethereum/sync
ethereum/consensus
ethereum/rpc
ethereum/graphql

Current state of the tests

These Hive suites/simulators can be run:

ethereum/consensus
ethereum/graphql

These Hive suites/simulators don't work with nimbus-eth1 currently:

devp2p/discv4
devp2p/eth
ethereum/rpc
ethereum/sync

The number of passes and fails output at the time of writing (2021-04-26) is:

ethereum/consensus:  27353 pass,   892 fail, 28245 total
ethereum/graphql:       36 pass,    10 fail,    46 total
devp2p/discv4:           0 pass,    14 fail,    14 total
devp2p/eth:              0 pass,     1 fail,     1 total
ethereum/rpc:            3 pass,    35 fail,    38 total
ethereum/sync:           0 pass,     1 fail,     1 total
