Serban Iorga dfc8e4696c Bridge zombienet tests refactoring (#3260 )

Related to https://github.com/paritytech/polkadot-sdk/issues/3242

Reorganizing the bridge zombienet tests in order to:
- separate the environment spawning from the actual tests
- offer better control over the tests and some possibility to
orchestrate them as opposed to running everything from the zndsl file

Only rewrote the asset transfer test using this new "framework". The old
logic and old tests weren't functionally modified or deleted. The plan
is to get feedback on this approach first and if this is agreed upon,
migrate the other 2 tests later in separate PRs and also do other
improvements later.

Bridge-hub Parachains

Bridge-hub Parachains

BridgeHub(s) are system parachains that will house trustless bridges from the local ecosystem to others. The current trustless bridges planned for the BridgeHub(s) are:

BridgeHubPolkadot system parachain:
1. Polkadot <-> Kusama bridge
2. Polkadot <-> Ethereum bridge (Snowbridge)
BridgeHubKusama system parachain:
1. Kusama <-> Polkadot bridge
2. Kusama <-> Ethereum bridge The high-level responsibilities of each bridge living on BridgeHub:
sync finality proofs between relay chains (or equivalent)
sync finality proofs between BridgeHub parachains
pass (XCM) messages between different BridgeHub parachains

Requirements for local run/testing

# Prepare empty directory for testing
mkdir -p ~/local_bridge_testing/bin
mkdir -p ~/local_bridge_testing/logs

---
# 1. Install zombienet
Go to: https://github.com/paritytech/zombienet/releases
Copy the apropriate binary (zombienet-linux) from the latest release to ~/local_bridge_testing/bin


---
# 2. Build polkadot binary

We need polkadot binary with "fast-runtime" feature:

cd <polkadot-sdk-git-repo-dir>
cargo build --release --features fast-runtime --bin polkadot
cp target/release/polkadot ~/local_bridge_testing/bin/polkadot

cargo build --release --features fast-runtime --bin polkadot-prepare-worker
cp target/release/polkadot-prepare-worker ~/local_bridge_testing/bin/polkadot-prepare-worker

cargo build --release --features fast-runtime --bin polkadot-execute-worker
cp target/release/polkadot-execute-worker ~/local_bridge_testing/bin/polkadot-execute-worker


---
# 3. Build substrate-relay binary
git clone https://github.com/paritytech/parity-bridges-common.git
cd parity-bridges-common

# checkout desired branch or use master:
# git checkout -b master --track origin/master
# `polkadot-staging` (recommended) is stabilized and compatible for Cumulus releases
# `master` is latest development
git checkout -b polkadot-staging --track origin/polkadot-staging

cargo build --release -p substrate-relay
cp target/release/substrate-relay ~/local_bridge_testing/bin/substrate-relay


---
# 4. Build cumulus polkadot-parachain binary
cd <polkadot-sdk-git-repo-dir>

cargo build --release -p polkadot-parachain-bin
cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain
cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain-asset-hub

How to test local Rococo <-> Westend bridge

Run Rococo/Westend chains with zombienet

cd <polkadot-sdk-git-repo-dir>

# Rococo + BridgeHubRococo + AssetHub for Rococo (mirroring Kusama)
POLKADOT_BINARY=~/local_bridge_testing/bin/polkadot \
POLKADOT_PARACHAIN_BINARY=~/local_bridge_testing/bin/polkadot-parachain \
	~/local_bridge_testing/bin/zombienet-linux --provider native spawn ./cumulus/zombienet/bridge-hubs/bridge_hub_rococo_local_network.toml

cd <polkadot-sdk-git-repo-dir>

# Westend + BridgeHubWestend + AssetHub for Westend (mirroring Polkadot)
POLKADOT_BINARY=~/local_bridge_testing/bin/polkadot \
POLKADOT_PARACHAIN_BINARY=~/local_bridge_testing/bin/polkadot-parachain \
	~/local_bridge_testing/bin/zombienet-linux --provider native spawn ./cumulus/zombienet/bridge-hubs/bridge_hub_westend_local_network.toml

Init bridge and run relayer between BridgeHubRococo and BridgeHubWestend

Accounts of BridgeHub parachains:

Bob is pallet owner of all bridge pallets

Run with script

cd <polkadot-sdk-git-repo-dir>

./cumulus/scripts/bridges_rococo_westend.sh run-relay

Check relay-chain headers relaying:

Rococo parachain: - https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A8943#/chainstate - Pallet: bridgeWestendGrandpa - Keys: bestFinalized()
Westend parachain: - https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A8945#/chainstate - Pallet: bridgeRococoGrandpa - Keys: bestFinalized()

Check parachain headers relaying:

Rococo parachain: - https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A8943#/chainstate - Pallet: bridgeWestendParachains - Keys: parasInfo(None)
Westend parachain: - https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A8945#/chainstate - Pallet: bridgeRococoParachains - Keys: parasInfo(None)

Initialize configuration for transfer asset over bridge (ROCs/WNDs)

This initialization does several things:

creates ForeignAssets for wrappedROCs/wrappedWNDs
drips SA for AssetHubRococo on AssetHubWestend (and vice versa) which holds reserved assets on source chains

cd <polkadot-sdk-git-repo-dir>

./cumulus/scripts/bridges_rococo_westend.sh init-asset-hub-rococo-local
./cumulus/scripts/bridges_rococo_westend.sh init-bridge-hub-rococo-local
./cumulus/scripts/bridges_rococo_westend.sh init-asset-hub-westend-local
./cumulus/scripts/bridges_rococo_westend.sh init-bridge-hub-westend-local

Send messages - transfer asset over bridge (ROCs/WNDs)

Do reserve-backed transfers:

cd <polkadot-sdk-git-repo-dir>

# ROCs from Rococo's Asset Hub to Westend's.
./cumulus/scripts/bridges_rococo_westend.sh reserve-transfer-assets-from-asset-hub-rococo-local

cd <polkadot-sdk-git-repo-dir>

# WNDs from Westend's Asset Hub to Rococo's.
./cumulus/scripts/bridges_rococo_westend.sh reserve-transfer-assets-from-asset-hub-westend-local

open explorers: (see zombienets)
- AssetHubRococo (see events xcmpQueue.XcmpMessageSent, polkadotXcm.Attempted) https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:9910#/explorer
- BridgeHubRococo (see bridgeWestendMessages.MessageAccepted) https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:8943#/explorer
- BridgeHubWestend (see bridgeRococoMessages.MessagesReceived, xcmpQueue.XcmpMessageSent) https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:8945#/explorer
- AssetHubWestend (see foreignAssets.Issued, xcmpQueue.Success) https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:9010#/explorer
- BridgeHubRocococ (see bridgeWestendMessages.MessagesDelivered) https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:8943#/explorer

Do reserve withdraw transfers: (when previous is finished)

cd <polkadot-sdk-git-repo-dir>

# wrappedWNDs from Rococo's Asset Hub to Westend's.
./cumulus/scripts/bridges_rococo_westend.sh withdraw-reserve-assets-from-asset-hub-rococo-local

cd <polkadot-sdk-git-repo-dir>

# wrappedROCs from Westend's Asset Hub to Rococo's.
./cumulus/scripts/bridges_rococo_westend.sh withdraw-reserve-assets-from-asset-hub-westend-local

Claim relayer's rewards on BridgeHubRococo and BridgeHubWestend

//Charlie is relayer account on BridgeHubRococo
//Charlie is relayer account on BridgeHubWestend

cd <polkadot-sdk-git-repo-dir>

# Claim rewards on BridgeHubWestend:
