Pre-requisites

• node 8
• npm

Installation

1. NPM Scripts

npm install

This pulls some dependency repos, such as the contracts repo and the chainspec generator.

npm run compile

This compiles the contracts with a local truffle in order to obtain their ABI.

2. Test Accounts

Since these tests run on a live chain, some unlocked accounts with ethers are needed for testing.

The tests expect the test accounts to be in the accounts/testaccounts.json file. Use the template snippet below to paste your private keys and place it there. Important:

• This file must not be commited.
• You need to add at least 3 addresses.
• The first two addresses must be VALIDATOR_NETOPS and COMMUNITY_FUND multisig contract owners. These accounts also need to be funded before the tests can be executed.
• This means that the VALIDATOR_NETOPS and COMMUNITY_FUND multisig must to have a confirmation threshold of 2 to run the tests successfully.
• The third address can be an address of your choosing.

accounts/testaccounts.json template:

[
    {
        "privateKey": "0xaddhere",
        "address": "0xaddhere"
    },
    {
        "privateKey": "0xaddhere",
        "address": "0xaddhere"
    },
    {
        "privateKey": "0xaddhere",
        "address": "0xaddhere"
    }
]

3. Run Local Client

Download an EWF chain spec file, e.g. for Volta and run:

parity --chain ./Volta.json --jsonrpc-apis=all --jsonrpc-cors=all --ipc-apis=all --ws-apis=all --ws-origins=all --no-persistent-txqueue --no-warp --pruning=archive

Important: leave the rpc and ws interfaces at their default setting: local. The default ports 8545 for rpc and 8546 for ws are used by the tests.

Test Execution

To run the tests, execute:

npm test

Important: Do not stop the tests before they are completed. Stopping the tests may lead to an unclean state which needs to be cleand manually.

Guidelines

• Scripts: the folder utils contains useful Python scripts
• Sanity (integration) tests: Mocha tests (inspired by the unit tests)
• Security tests: Mocha tests
