EVM Tests for Telos EVM

REQUIREMENTS

This template requires NodeJS & NPM installed on your machine and a wallet address on the Telos EVM Testnet Network.

Commands used below work on recent Linux or Windows versions but have not been verified for Mac

INSTALL

• Install the repository on your machine
• Enter the directory of the project on your machine and install its dependencies by running npm install

TEST

• Use npx hardhat test to build and launch the tests

OPTIONAL:

Run local evm node & autodeploy contract at tevmc/contracts/eosio.evm

Requirements:

• Docker
• Python 3.9+ (probably works with 3.7+ but haven't tested in a while)
• Linux (for now)

Quickstart:

# from repo root:

# create virtualenv and activate
python3 -m venv venv
source venv/bin/activate

# install requirements
pip install -r tevmc/requirements.txt

# run deploy script, will wait for user input for teardown
pytest tevmc/test_deploy.py

# on another terminal run js evm tests
npx hardhat test --network tevmc

evm-tests's Issues

Add getStorageAt test

Run a getStorageAt test against tevm 1.5 an erigon node

Add estimateGas max value balance test

Description

Setting the maximum amount of a sender in value returns an error. We need a test for it to reproduce:

Hi there!
Could you help me guys with fee calculation?
I see if I send to RPC eth_estimatedGas (for send tx) it returns const value despite amount value I set. But if I send maximum amount for address, api returns error. What amount should we use to get estimatedGas for transaction?

Figure out why the provider isn't stopping the gas estimation call for Telos

Description

Test revealed that on gas estimation with a gas fee specified but no balance in the wallet, the call reverts with The sender address has a zero balance on Telos but Sepolia gives a provider error 'insufficient funds for intrinsic transaction cost' and doesn't even make the call.

Task

• Figure out why the provider isn't stopping the call for Telos.

Add getLogs tests

Description

Make sure our getLogs response is the same as Erigon's

Following was reported by a partner

When querying logs on the RPC, topic filters seem to not be working when an array with multiple values is passed as filter parameter. Then eth_getLogs simply returns nothing anymore. Setting the filter as single value works, but passing multiple values, which should create an or, does not work.

e.g.:

{
  'topics': ['0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef',
     [
       '0x000000000000000000000000905caae1627856529bed7b9572f02af5e5ac6ca7', 
       '0x0000000000000000000000000000000000000000000000000000000000000000'
     ]
  ]
} 

does not work, while

{
  'topics': ['0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef',
    ['0x0000000000000000000000000000000000000000000000000000000000000000']
  ]
} 

works. Difference is the second element in the array.

Add test for estimateGas success & failures

Description

We should add tests for estimateGas success & failure (contract revert, lack of gas fee funds) to behave like Goerli

Add test for internal call failing but the transaction continues

Description

Add test for internal call failing but the transaction continues

We should see how to force an out of gas failure as well, and do that in these tests too. The original create2 internal transaction contract deployment failure was due to out of gas, which might have a different response than a contract revert

Setup diff tester between tEVM and Sepolia responses

Description

We need to capture responses from a sepolia node and compare them to our responses using different calls & situations such as eth_call, eth_estimateGas and trace_transaction

Add test for factories deploying a contract and that contract fails

Description

We need a test for factories deploying a contract and that contract fails

We should see how to force an out of gas failure as well, and do that in these tests too. The original create2 internal transaction contract deployment failure was due to out of gas, which might have a different response than a contract revert
