PyTest Integration

The true power of mapping smart contracts onto native Python is leveraging the thousands of mature industry-grade open source developer tools already established.

You can natively test your PyVax EVM transpilation using pytest without spinning up Hardhat, Foundry, or local Ganache EVM instances.

Bootstrapping a Local Environment

PyVax exposes an isolated in-memory testing RPC MockChain() that correctly simulates EVM Opcodes and reverts without requiring background node synchronization.

python

# test_vault.py
import pytest
from pyvax import MockChain, AgentWallet
from src.vault import AgentVault

@pytest.fixture
def chain():
    # Instantiates the zero-latency PyVax EVM Simulator
    env = MockChain()
    return env

@pytest.fixture
def accounts(chain):
    # Generates 3 funded testing wallets mapping 10.0 AVAX 
    return chain.generate_wallets(3, balance=10.0)

def test_autonomous_deposit(chain, accounts):
    human, agent_1, _ = accounts
    
    # Simulate a true deployment
    contract = chain.deploy(AgentVault)
    
    amount = 5.0
    
    # 1. Human safely executes deposit externally
    tx_1 = human.execute(contract, "deposit", [amount])
    assert tx_1.status == "SUCCESS"
    assert contract.balance(human) == 5.0
    
    # 2. Agent successfully validates its `@agent_action`
    tx_2 = agent_1.execute(contract, "autonomous_rebalance", [])
    assert tx_2.status == "SUCCESS"
    
    # 3. Simulate adversarial human attempting Agent-Only access
    with pytest.raises(chain.TransactionRevertedError):
        human.execute(contract, "autonomous_rebalance", [])

Running the Matrix

bash

$ pytest test_vault.py -v

# test_vault.py::test_autonomous_deposit PASSED [100%]

A Note on CI/CD

Because MockChain does not require complex Docker architectures or Docker-Compose sidecars running actual Avalanche nodes, your GitHub Actions run lightning fast natively executing Python code.
