Multi-Chain Registration & Cross-Site Synchronization

Objective

Test the new multi-chain capabilities across the live system where:

  1. One single node instance hosts multiple independent chains (ait-devnet, ait-testnet, ait-healthchain)
  2. Nodes across aitbc and aitbc1 correctly synchronize independent chains using their chain_id

Automated Test Execution

Using the Testing Skill

# Execute multi-chain tests using the testing skill
skill test

# Run specific multi-chain test scenarios
python -m pytest tests/integration/test_multichain.py -v

# Run all tests including multi-chain scenarios
./scripts/testing/run_all_tests.sh

Using CLI for Testing

# Test CLI connectivity to multi-chain endpoints
cd /home/oib/windsurf/aitbc/cli
source venv/bin/activate

# Test health endpoint
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key health

# Test multi-chain status
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain chains

Test Phase 1: Multi-Chain Live Verification

1.1 Check Multi-Chain Status on aitbc

# Verify multiple chains are active on aitbc node
curl -s "http://127.0.0.1:8000/v1/health" | jq .supported_chains

# Expected response:
# [
#   "ait-devnet",
#   "ait-testnet",
#   "ait-healthchain"
# ]

# Alternative using CLI
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain chains

1.2 Verify Independent Genesis Blocks

# Get genesis for devnet
curl -s "http://127.0.0.1:8082/rpc/blocks/0?chain_id=ait-devnet" | jq .hash

# Get genesis for testnet (should be different from devnet)
curl -s "http://127.0.0.1:8082/rpc/blocks/0?chain_id=ait-testnet" | jq .hash

# Get genesis for healthchain (should be different from others)
curl -s "http://127.0.0.1:8082/rpc/blocks/0?chain_id=ait-healthchain" | jq .hash

# Alternative using CLI
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain genesis --chain-id ait-devnet
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain genesis --chain-id ait-testnet
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain genesis --chain-id ait-healthchain

Test Phase 2: Isolated Transaction Processing

2.1 Submit Transaction to Specific Chain

# Submit TX to healthchain
curl -s -X POST "http://127.0.0.1:8082/rpc/sendTx?chain_id=ait-healthchain" \
  -H "Content-Type: application/json" \
  -d '{"sender":"alice","recipient":"bob","payload":{"data":"medical_record"},"nonce":1,"fee":0,"type":"TRANSFER"}'

# Expected response:
# {
#   "tx_hash": "0x..."
# }

# Alternative using CLI
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain send \
  --chain-id ait-healthchain \
  --from alice \
  --to bob \
  --data "medical_record" \
  --nonce 1

2.2 Verify Chain Isolation

# Check mempool on healthchain (should have 1 tx)
curl -s "http://127.0.0.1:8082/rpc/mempool?chain_id=ait-healthchain"

# Check mempool on devnet (should have 0 tx)
curl -s "http://127.0.0.1:8082/rpc/mempool?chain_id=ait-devnet"

# Alternative using CLI
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain mempool --chain-id ait-healthchain
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain mempool --chain-id ait-devnet

Test Phase 3: Cross-Site Multi-Chain Synchronization

3.1 Verify Sync to aitbc1

# Wait for block proposal (interval is 2s)
sleep 5

# Check block on aitbc (Primary)
curl -s "http://127.0.0.1:8082/rpc/head?chain_id=ait-healthchain" | jq .

# Check block on aitbc1 (Secondary) - Should match exactly
ssh aitbc1-cascade "curl -s \"http://127.0.0.1:8082/rpc/head?chain_id=ait-healthchain\"" | jq .

# Alternative using CLI
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key blockchain head --chain-id ait-healthchain

Test Phase 4: Automated Test Suite Execution

4.1 Run Complete Test Suite

# Execute all tests including multi-chain scenarios
./scripts/testing/run_all_tests.sh

# Run specific multi-chain integration tests
python -m pytest tests/integration/test_multichain.py -v

# Run CLI tests with multi-chain support
python -m pytest tests/cli/test_cli_integration.py -v

4.2 Test Result Validation

# Generate test coverage report
python -m pytest tests/ --cov=. --cov-report=html

# View test results
open htmlcov/index.html

# Check specific test results
python -m pytest tests/integration/test_multichain.py::TestMultiChain::test_chain_isolation -v

Integration with Test Framework

Test Configuration

The multi-chain tests integrate with the main test framework through:

  • conftest.py: Shared test fixtures and configuration
  • test_cli_integration.py: CLI integration testing
  • test_integration/: Service integration tests
  • run_all_tests.sh: Comprehensive test execution

Environment Setup

# Set up test environment for multi-chain testing
export PYTHONPATH="/home/oib/windsurf/aitbc/cli:/home/oib/windsurf/aitbc/packages/py/aitbc-core/src:/home/oib/windsurf/aitbc/packages/py/aitbc-crypto/src:/home/oib/windsurf/aitbc/packages/py/aitbc-sdk/src:/home/oib/windsurf/aitbc/apps/coordinator-api/src:$PYTHONPATH"
export TEST_MODE=true
export TEST_DATABASE_URL="sqlite:///:memory:"
export _AITBC_NO_RICH=1

Mock Services

The test framework provides comprehensive mocking for:

  • HTTP Clients: httpx.Client mocking for API calls
  • Blockchain Services: Mock blockchain responses
  • Multi-Chain Coordination: Mock chain synchronization
  • Cross-Site Communication: Mock P2P gossip

Troubleshooting

Common Issues

  • Connection Refused: Check if coordinator API is running
  • Chain Not Found: Verify chain configuration
  • Sync Failures: Check P2P network connectivity
  • Test Failures: Review test logs and configuration

Debug Mode

python -m pytest tests/integration/test_multichain.py -v -s --tb=long

# Run specific test with debugging
python -m pytest tests/integration/test_multichain.py::TestMultiChain::test_chain_isolation -v -s --pdb

Service Status

# Check coordinator API status
curl -s "http://127.0.0.1:8000/v1/health"

# Check blockchain node status
curl -s "http://127.0.0.1:8082/rpc/status"

# Check CLI connectivity
python -m aitbc_cli --url http://127.0.0.1:8000 --api-key test-key health
